a7fa18c203 py/builtinimport: Refactor module importing.
Simplify and document/comment the handling of builtin import for:
- already-loaded modules
- built-in modules
- built-in umodules (formerly weak links)
- filesystem modules

Retains existing functionality with smaller code size but should also
facilitate potential new features (built-in packages, controlling the
frozen path).

Also makes the (unix-only) -m behavior a bit more obvious and configurable.

Initial broadcom port for Raspberry Pi
This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.

There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
  themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
  mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
  and unnecessary for the vast majority of builds.

Fixes #4314

e2ca8ab8fc py/runtime: Allow types to use both .attr and .locals_dict.
Make it possible to proceed to a regular lookup in locals_dict if the
custom type->attr fails.  This allows type->attr to extend rather than
completely replace the lookup in locals_dict.

This is useful for custom builtin classes that have mostly regular methods
but just a few special attributes/properties.  This way, type->attr needs
to deal with the special cases only and the default lookup will be used for
generic methods.

a8614a61dc ParallelImageCapture: Add continuous capture on espressif
By having a pair of buffers, the capture hardware can fill one buffer while
Python code (including displayio, etc) operates on the other buffer.  This
increases the responsiveness of camera-using code.

On the Kaluga it makes the following improvements:
 * 320x240 viewfinder at 30fps instead of 15fps using directio
 * 240x240 animated gif capture at 10fps instead of 7.5fps

As discussed at length on Discord, the "usual end user" code will look like
this:

    camera = ...

    with camera.continuous_capture(buffer1, buffer2) as capture:
        for frame in capture:
            # Do something with frame

However, rather than presenting a context manager, the core code consists of
three new functions to start & stop continuous capture, and to get the next
frame.  The reason is twofold.  First, it's simply easier to implement the
context manager object in pure Python.  Second, for more advanced usage, the
context manager may be too limiting, and it's easier to iterate on the right
design in Python code.  In particular, I noticed that adapting the
JPEG-capturing programs to use continuous capture mode needed a change in
program structure.

The camera app was structured as
```python
while True:
    if shutter button was just pressed:
        capture a jpeg frame
    else:
        update the viewfinder
```

However, "capture a jpeg frame" needs to (A) switch the camera settings and (B)
capture into a different, larger buffer then (C) return to the earlier
settings. This can't be done during continuous capture mode. So just
restructuring it as follows isn't going to work:

```python
with camera.continuous_capture(buffer1, buffer2) as capture:
    for frame in capture:
        if shutter button was just pressed:
            capture a jpeg frame, without disturbing continuous capture mode
        else:
            update the viewfinder
```

The continuous mode is only implemented in the espressif port; others
will throw an exception if the associated methods are invoked.  It's not
impossible to implement there, just not a priority, since these micros don't
have enough RAM for two framebuffer copies at any resonable sizes.

The capture code, including single-shot capture, now take mp_obj_t in the
common-hal layer, instead of a buffer & length.  This was done for the
continuous capture mode because it has to identify & return to the user the
proper Python object representing the original buffer.  In the Espressif port,
it was convenient to implement single capture in terms of a multi-capture,
which is why I changed the singleshot routine's signature too.

694af3dd23 main: redesign boot_out.txt writing
New design:
 * capture output to a vstr
 * compare the complete vstr to boot_out.txt
 * rewrite if not a complete match

This is resilient against future changes to the automatic
text written to boot_out.txt.

This also fixes rewriting boot_out.txt in the case where
boot.py prints something.

Perhaps it also saves a bit of code space. Some tricks:
 * no need to close a file in read mode
 * no need to switch on/off USB write access, going down to the
   oofatfs layer doesn't check it anyway

fe120484b6 py/gc: Add hook to run code during time consuming GC operations.
This makes it possible for cooperative multitasking systems to keep running
event loops during garbage collector operations.

For example, this can be used to ensure that a motor control loop runs
approximately each 5 ms.  Without this hook, the loop time can jump to
about 15 ms.

Addresses #3475.

c34b6f757f Implement gifio.GifWriter
This involves:
 * Adding a new "L8" colorspace for colorconverters
 * factoring out displayio_colorconverter_convert_pixel
 * Making a minimal "colorspace only" version of displayio for the
   unix port (testing purposes)
 * fixing an error message

I only tested writing B&W animated images, with the following script:
```python
import displayio
import gifio

with gifio.GifWriter("foo.gif", 64, 64, displayio.Colorspace.L8) as g:
    for i in range(0, 256, 14):
        data = bytes([i, 255-i] * 32 + [255-i, i] * 32) * 32
        print("add_frame")
        g.add_frame(data)

# expected to raise an error, buffer is not big enough
with gifio.GifWriter("/dev/null", 64, 64, displayio.Colorspace.L8) as g:
    g.add_frame(bytes([3,3,3]))

74457d81f2 str_modulo_format: Make error better match standard python
Before this, "%c" % 3.14 would raise the error `integer required`
even though python3 uses `%c requires int or char`, just like both
already did for "%c" % "ab".

This gets rid of a string to translate, and makes behavior match
python3 better.

F-strings, new machine.I2S class, ESP32-C3 support and LEGO_HUB_NO6 board

This release of MicroPython adds support for f-strings (PEP-498), with a
few limitations compared to normal Python.  F-strings are essentially
syntactic sugar for "".format() and make formatting strings a lot more
convenient.  Other improvements to the core runtime include pretty printing
OSError when it has two arguments (an errno code and a string), scheduling
of KeyboardInterrupt on the main thread, and support for a single argument
to the optimised form of StopIteration.

In the machine module a new I2S class has been added, with support for
esp32 and stm32 ports.  This provides a consistent API for transmit and
receive of audio data in blocking, non-blocking and asyncio-based
operation.  Also, the json module has support for the "separators" argument
in the dump and dumps functions, and framebuf now includes a way to blit
between frame buffers of different formats using a palette.  A new,
portable machine.bitstream function is also added which can output a stream
of bits with configurable timing, and is used as the basis for driving
WS2812 LEDs in a common way across ports.

There has been some restructuring of the repository directory layout, with
all third-party code now in the lib/ directory.  And a new top-level
directory shared/ has been added with first-party code that was previously
in lib/ moved there.

The docs have seen further improvement with enhancements and additions to
the rp2 parts, as well as a new quick reference for the zephyr port.
The terms master/slave have been replaced with controller/peripheral,
mainly relating to I2C and SPI usage.  And u-module references have been
replaced with just the module name without the u-prefix to help clear up
the intended usage of modules in MicroPython.

For the esp8266 and esp32 ports, hidden networks are now included in WLAN
scan results.  On the esp32 the RMT class is enhanced with idle_level and
write_pulses modes.  There is initial support for ESP32-C3 chips with
GENERIC_C3 and GENERIC_C3_USB boards.

The javascript port has had its Makefile and garbage collector
implementation reworked so it compiles and runs with latest the Emscripten
using asyncify.

The mimxrt port sees the addition of hardware I2C and SPI support, as well
as some additional methods to the machine module.  There is also support
for Hyperflash chips.

The nrf port now has full VFS storage support, enables source-line on
traceback, and has .mpy features consistent with other ports.

For the rp2 port there is now more configurability for boards, and more
boards added.

The stm32 port has a new LEGO_HUB_NO6 board definition with detailed
information how to get this LEGO Hub running stock MicroPython.  There is
also now support to change the CPU frequency on STM32WB MCUs.  And USBD_xxx
descriptor options have been renamed to MICROPY_HW_USB_xxx.

b326edf68c all: Remove MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
This commit removes all parts of code associated with the existing
MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE optimisation option, including the
-mcache-lookup-bc option to mpy-cross.

This feature originally provided a significant performance boost for Unix,
but wasn't able to be enabled for MCU targets (due to frozen bytecode), and
added significant extra complexity to generating and distributing .mpy
files.

The equivalent performance gain is now provided by the combination of
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE (which has
been enabled on the unix port in the previous commit).

It's hard to provide precise performance numbers, but tests have been run
on a wide variety of architectures (x86-64, ARM Cortex, Aarch64, RISC-V,
xtensa) and they all generally agree on the qualitative improvements seen
by the combination of MICROPY_OPT_LOAD_ATTR_FAST_PATH and
MICROPY_OPT_MAP_LOOKUP_CACHE.

For example, on a "quiet" Linux x64 environment (i3-5010U @ 2.10GHz) the
change from CACHE_MAP_LOOKUP_IN_BYTECODE, to LOAD_ATTR_FAST_PATH combined
with MAP_LOOKUP_CACHE is:

diff of scores (higher is better)
N=2000 M=2000       bccache -> attrmapcache      diff      diff% (error%)
bm_chaos.py        13742.56 ->   13905.67 :   +163.11 =  +1.187% (+/-3.75%)
bm_fannkuch.py        60.13 ->      61.34 :     +1.21 =  +2.012% (+/-2.11%)
bm_fft.py         113083.20 ->  114793.68 :  +1710.48 =  +1.513% (+/-1.57%)

bm_nqueens.py     197544.25 ->  217713.12 : +20168.87 = +10.210% (+/-3.01%)
bm_pidigits.py      8072.98 ->    8198.75 :   +125.77 =  +1.558% (+/-3.22%)
misc_aes.py        17283.45 ->   16480.52 :   -802.93 =  -4.646% (+/-0.82%)
misc_mandel.py     99083.99 ->  128939.84 : +29855.85 = +30.132% (+/-5.88%)
misc_pystone.py    83860.10 ->   82592.56 :  -1267.54 =  -1.511% (+/-2.27%)
misc_raytrace.py   21490.40 ->   22227.23 :   +736.83 =  +3.429% (+/-1.88%)

This shows that the new optimisations are at least as good as the existing
inline-bytecode-caching, and are sometimes much better (because the new
ones apply caching to a wider variety of map lookups).

The new optimisations can also benefit code generated by the native
emitter, because they apply to the runtime rather than the generated code.
The improvement for the native emitter when LOAD_ATTR_FAST_PATH and
MAP_LOOKUP_CACHE are enabled is (same Linux environment as above):

diff of scores (higher is better)
N=2000 M=2000        native -> nat-attrmapcache  diff      diff% (error%)
bm_chaos.py        14130.62 ->   15464.68 :  +1334.06 =  +9.441% (+/-7.11%)
bm_fannkuch.py        74.96 ->      76.16 :     +1.20 =  +1.601% (+/-1.80%)
bm_fft.py         166682.99 ->  168221.86 :  +1538.87 =  +0.923% (+/-4.20%)
bm_float.py       233415.23 ->  265524.90 : +32109.67 = +13.756% (+/-2.57%)
bm_hexiom.py         628.59 ->     734.17 :   +105.58 = +16.796% (+/-1.39%)
bm_nqueens.py     225418.44 ->  232926.45 :  +7508.01 =  +3.331% (+/-3.10%)
bm_pidigits.py      6322.00 ->    6379.52 :    +57.52 =  +0.910% (+/-5.62%)
misc_aes.py        20670.10 ->   27223.18 :  +6553.08 = +31.703% (+/-1.56%)
misc_mandel.py    138221.11 ->  152014.01 : +13792.90 =  +9.979% (+/-2.46%)
misc_pystone.py    85032.14 ->  105681.44 : +20649.30 = +24.284% (+/-2.25%)
misc_raytrace.py   19800.01 ->   23350.73 :  +3550.72 = +17.933% (+/-2.79%)

In summary, compared to MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE, the new
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE options:
- are simpler;
- take less code size;
- are faster (generally);
- work with code generated by the native emitter;
- can be used on embedded targets with a small and constant RAM overhead;
- allow the same .mpy bytecode to run on all targets.

See #7680 for further discussion.  And see also #7653 for a discussion
about simplifying mpy-cross options.

11ef8f22fe py/map: Add an optional cache of (map+index) to speed up map lookups.
The existing inline bytecode caching optimisation, selected by
MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE, reserves an extra byte in the
bytecode after certain opcodes, which at runtime stores a map index of the
likely location of this field when looking up the qstr.  This scheme is
incompatible with bytecode-in-ROM, and doesn't work with native generated
code.  It also stores bytecode in .mpy files which is of a different format
to when the feature is disabled, making generation of .mpy files more
complex.

This commit provides an alternative optimisation via an approach that adds
a global cache for map offsets, then all mp_map_lookup operations use it.
It's less precise than bytecode caching, but allows the cache to be
independent and external to the bytecode that is executing.  It also works
for the native emitter and adds a similar performance boost on top of the
gain already provided by the native emitter.

7b89ad8dbf py/vm: Add a fast path for LOAD_ATTR on instance types.
When the LOAD_ATTR opcode is executed there are quite a few different cases
that have to be handled, but the common case is accessing a member on an
instance type.  Typically, built-in types provide methods which is why this
is common.

Fortunately, for this specific case, if the member is found in the member
map then there's no further processing.

This optimisation does a relatively cheap check (type is instance) and then
forwards directly to the member map lookup, falling back to the regular
path if necessary.

01374d941f py/mpconfig.h: Define initial templates for "feature levels".
This is the beginning of a set of changes to simplify enabling/disabling
features.  The goals are:
- Remove redundancy from mpconfigport.h (never set a value to the default
  -- make it clear exactly what's being enabled).
- Improve consistency between ports.  All "similar" ports (i.e. approx same
  flash size) should get the same features.
- Simplify mpconfigport.h -- just get default/sensible options for the size
  of the port.
- Make it easy for defining constrained boards (e.g. STM32F0/L0), they can
  just set a lower level.

This commit makes a step towards this and defines the "core" level as the
current default feature set, and a "minimal" level to turn off everything.
And a few placeholder levels are added for where the other ports will
roughly land.

This is a no-op change for all ports.

e6850838cd py/parse: Simplify parse nodes representing a list.
This commit simplifies and optimises the parse tree in-memory
representation of lists of expressions, for tuples and lists, and when
tuples are used on the left-hand-side of assignments and within del
statements.  This reduces memory usage of the parse tree when such code is
compiled, and also reduces the size of the compiler.

For example, (1,) was previously the following parse tree:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=2)
          int(1)
          testlist_comp_3b(149) (n=1)
            NULL
      NULL

and with this commit is now:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=1)
          int(1)
      NULL

Similarly, (1, 2, 3) was previously:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=2)
          int(1)
          testlist_comp_3c(150) (n=2)
            int(2)
            int(3)
      NULL

and is now:

    expr_stmt(5) (n=2)
      atom_paren(45) (n=1)
        testlist_comp(146) (n=3)
          int(1)

adding boot counter to main.c
The boot counter is a uint8_t single-byte counter stored in the first NVM byte position (`micrcontroller.nvm[0]`). The counter increments by 1 each time the board boots, regardless if it's a hard or soft reset. 

Enable the boot counter by adding `#define CIRCUITPY_BOOT_COUNTER 1` to your board's mpconfigboard.h file. Note that an error will be thrown during the build if `CIRCUITPY_INTERNAL_NVM_SIZE` is not also set within mpconfigboard.h.

266b6a1dd9 mkrules: Fix warning preprocessing C++ files
Messages like 'command-line option is [not valid] for C++' can result
from the way the preprocessor is invoked by `genlast`.  Instead, cause
the files to be preprocessed as though their content is "C".  This
should generally be OK, as they'll eventually be _compiled_ as C++.
When preprocessed as C, the file simply needs to generate all the same
QSTRS and TRANSLATEs.

692d36d779 py: Implement partial PEP-498 (f-string) support.
This implements (most of) the PEP-498 spec for f-strings and is based on
https://github.com/micropython/micropython/pull/4998 by @klardotsh.

It is implemented in the lexer as a syntax translation to `str.format`:
  f"{a}" --> "{}".format(a)

It also supports:
  f"{a=}" --> "a={}".format(a)

This is done by extracting the arguments into a temporary vstr buffer,
then after the string has been tokenized, the lexer input queue is saved
and the contents of the temporary vstr buffer are injected into the lexer
instead.

There are four main limitations:
- raw f-strings (`fr` or `rf` prefixes) are not supported and will raise
  `SyntaxError: raw f-strings are not supported`.

- literal concatenation of f-strings with adjacent strings will fail
    "{}" f"{a}" --> "{}{}".format(a)    (str.format will incorrectly use
                                         the braces from the non-f-string)
    f"{a}" f"{a}" --> "{}".format(a) "{}".format(a) (cannot concatenate)

- PEP-498 requires the full parser to understand the interpolated
  argument, however because this entirely runs in the lexer it cannot
  resolve nested braces in expressions like
    f"{'}'}"

- The !r, !s, and !a conversions are not supported.

Includes tests and cpydiffs.

d59a28db97 Compress word offset table
By storing "count of words by length", the long `wends` table can be
replaced with a short `wlencount` table.  This saves flash storage space.

Extend the range of string lengths that can be in the dictionary.
Originally it was to 2 to 9; at one point it was changed to 3 to 9.
Putting the lower bound back at 2 has a positive impact on the French
translation (a bunch of them, such as "ch", "\r\n", "%q", are used).
Increasing the maximum length gets 'mpossible', ' doit être ',
and 'CircuitPyth' at the long end.  This adds a bit of processing time
to makeqstrdata. The specific 2/11 values are again empirical based on
the French translation on the adafruit_proxlight_trinkey_m0.

78718fffb1 py/mkrules: Automatically build mpy-cross if it doesn't exist.
Commit 4173950658 removed automatic building
of mpy-cross, which rebuilt it whenever any of its dependent source files
changed.

But needing to build mpy-cross, and not knowing how, is a frequent issue.
This commit aims to help by automatically building mpy-cross only if it
doesn't exist.  For Makefiles it uses an order-only prerequisite, while
for CMake it uses a custom command.

If MICROPY_MPYCROSS (which is what makemanifest.py uses to locate the
mpy-cross executable) is defined in the environment then automatic build
will not be attempted, allowing a way to prevent this auto-build if needed.

Thanks to Trammell Hudson aka @osresearch for the original idea; see #5760.

8836198ff1 TextSplitter: don't mutate 'words'
I was puzzled by why the dictionary words were sorted by length.
It was because TextSplitter sorted its parameter, instead of a copy.

This doesn't affect encoding size, but does affect the encoding NUMBER
of the found words.  We'll deliberately restore sorting by length next,
for other reasons, but not by spooky action.

2997113e73 obj.h: Make mp_obj_is_type work between full & non-full types
By comparing the address of the initial 'name' field instead of the
addresses of the objects themselves, a small amount of type safety is
added back, vs just casting to void.

In the event that some other kind of object is passed in as 't',
which happens to have a 'name' field of the right type, the construct
would be (undesirably) accepted but it would almost certainly evaluate
to false at runtime.

08e0e065f4 py/makeqstrdefs.py: Don't include .h files explicitly in preprocessing.
Only include .c and .cpp files explicitly in the list of files passed to
the preprocessor for QSTR extraction.  All relevant .h files will be
included in this process by "#include" from the .c(pp) files.  In
particular for moduledefs.h, this is included by py/objmodule.c (and
doesn't actually contain any extractable MP_QSTR_xxx, but rather defines
macros with MP_QSTR_xxx's in them which are then part of py/objmodule.c).

The main reason for this change is to simplify the preprocessing step on
the javascript port, which tries to compile .h files as C++ precompiled
headers if they are passed with -E to clang.

Testing was done on an amd64 Debian Buster system using gcc-8.3 and these
settings:

    CFLAGS += -g3 -Og -fsanitize=undefined
    LDFLAGS += -fsanitize=undefined

The introduced TASK_PAIRHEAP macro's conditional (x ? &x->i : NULL)
assembles (under amd64 gcc 8.3 -Os) to the same as &x->i, since i is the
initial field of the struct.  However, for the purposes of undefined
behavior analysis the conditional is needed.

259d9b69fe py/mpstate: Schedule KeyboardInterrupt on main thread.
This introduces a new macro to get the main thread and uses it to ensure
that asynchronous exceptions such as KeyboardInterrupt (CTRL+C) are only
scheduled on the main thread. This is more deterministic than being
scheduled on a random thread and is more in line with CPython that only
allow signal handlers to run on the main thread.

a70a4e6688 py/emitglue: Always flush caches when assigning native ARM code.
Prior to this commit, cache flushing for ARM native code was done only in
the assembler code asm_thumb_end_pass()/asm_arm_end_pass(), at the last
pass of the assembler.  But this misses flushing the cache when loading
native code from an .mpy file, ie in persistentcode.c.

The change here makes sure the cache is always flushed/cleaned/invalidated
when assigning native code on ARM architectures.

This problem was found running tests/micropython/import_mpy_native_gc.py on
the mimxrt port.

ca74f282fd modmath: Remove stray "pragma GCC diagnostic pop"
This caused an error when building on macos:

```
../../py/modmath.c:247:36: error: pragma diagnostic pop could not pop, no matching push [-Werror,-Wunknown-pragmas]
            #pragma GCC diagnostic pop
                                   ^
1 error generated.
```

The pragma was half-removed during the merge of micropython.

b6b39bff47 py/gc: Make gc_lock_depth have a count per thread.
This commit makes gc_lock_depth have one counter per thread, instead of one
global counter.  This makes threads properly independent with respect to
the GC, in particular threads can now independently lock the GC for
themselves without locking it for other threads.  It also means a given
thread can run a hard IRQ without temporarily locking the GC for all other
threads and potentially making them have MemoryError exceptions at random
locations (this really only occurs on MCUs with multiple cores and no GIL,
eg on the rp2 port).

The commit also removes protection of the GC lock/unlock functions, which
is no longer needed when the counter is per thread (and this also fixes the
cas where a hard IRQ calling gc_lock() may stall waiting for the mutex).

It also puts the check for `gc_lock_depth > 0` outside the GC mutex in
gc_alloc, gc_realloc and gc_free, to potentially prevent a hard IRQ from
waiting on a mutex if it does attempt to allocate heap memory (and putting
the check outside the GC mutex is now safe now that there is a
gc_lock_depth per thread).

aca9d5bc40 Fix up all natmod examples
* modframebuf: _mp_framebuf_p_t is not "really" a protocol, but the
   QSTR assignment caused problems when building as a dynamic module
 * modure: str_index_to_ptr is not in the natmod API, disable URE match
   spans when dynamic.  mp_obj_len() is a bugfix, we should throw here
   if the object is not string-like
 * moduzlib: Correct paths to uzlib headers & sources.  this relative
   path (from moduzlib.c to the referenced file) works in all cases,
   the other only worked from ports/PORTNAME.
 * dynruntime: Handle 2-arg m_malloc, assert_native_inited, add a
   micropythonish mp_arg_check_num_mp, fix mp_raise_msg to use dumb
   strings, add mp_raise_arg1
 * nativeglue: ad assert_native_inited
 * translate: MP_ERROR_TEXT evaluates to its argument for DYNRUNTIME
 * mpy-tool: A straggling magic number change
 * mpy_ld: Have to renumber manually after dynruntime change
 * import_mpy_native_gc.py: Update copy of features0 baked into this test
