Switch all ports to auto-growing split heap
This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.

On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.

This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.

Fixes #8512. Fixes #7334.

Angus Gratton 3e8aed9fcc py/gc: Add "max new split" value in result of gc.mem_free().
Follow-up to 519c24dd48 when MICROPY_GC_SPLIT_HEAP_AUTO is enabled, based
on discussion at
https://github.com/orgs/micropython/discussions/12316#discussioncomment-6858007

gc.mem_free() is always a heuristic, but this makes it a more useful
heuristic for common use cases.

Angus Gratton 519c24dd48 py/gc: Add new MICROPY_GC_SPLIT_HEAP_AUTO "auto grow heap" mode.
When set, the split heap is automatically extended with new areas on
demand, and shrunk if a heap area becomes empty during a GC pass or soft
reset.

To save code size the size allocation for a new heap block (including
metadata) is estimated at 103% of the failed allocation, rather than
working from the more complex algorithm in gc_try_add_heap(). This appears
to work well except in the extreme limit case when almost all RAM is
exhausted (~last few hundred bytes). However in this case some allocation
is likely to fail soon anyhow.

Currently there is no API to manually add a block of a given size to the
heap, although that could easily be added if necessary.

Damien Tournoud 2dcd745434 py/gc: Speed up incremental GC cycles by tracking the last used block.
In applications that use little memory and run GC regularly, the cost of
the sweep phase quickly becomes prohibitives as the amount of RAM
increases.

On an ESP32-S3 with 2 MB of external SPIRAM, for example, a trivial GC
cycle takes a minimum of 40ms, virtually all of it in the sweep phase.

Similarly, on the UNIX port with 1 GB of heap, a trivial GC takes 47 ms,
again virtually all of it in the sweep phase.

This commit speeds up the sweep phase in the case most of the heap is empty
by keeping track of the ID of the highest block we allocated in an area
since the last GC.

The performance benchmark run on PYBV10 shows between +0 and +2%
improvement across the existing performance tests.  These tests don't
really stress the GC, so they were also run with gc.threshold(30000) and
gc.threshold(10000).  For the 30000 case, performance improved by up to
+10% with this commit.  For the 10000 case, performance improved by at
least +10% on 6 tests, and up to +25%.

Changes in this commit:
- Add MICROPY_GC_HOOK_LOOP to gc_info() and gc_alloc().  Both of these can
  be long running (many milliseconds) which is too long to be blocking in
  some applications.
- Pass loop variable to MICROPY_GC_HOOK_LOOP(i) macro so that implementers
  can use it, e.g. to improve performance by only calling a function every
  X number of iterations.
- Drop outer call to MICROPY_GC_HOOK_LOOP in gc_mark_subtree().

Jim Mussared 256f47e2f8 extmod/btstack: Fix indicate/notify queuing.
This adds a mechanism to track a pending notify/indicate operation that
is deferred due to the send buffer being full. This uses a tracked alloc
that is passed as the content arg to the callback.

This replaces the previous mechanism that did this via the global pending
op queue, shared with client read/write ops.

Jeff Epler 9f434dd8de py/gc: Ensure a gap of one byte after the ATB.
Prior to this fix the follow crash occurred.  With a GC layout of:

    GC layout:
      alloc table at 0x3fd80428, length 32001 bytes, 128004 blocks
      finaliser table at 0x3fd88129, length 16001 bytes, 128008 blocks
      pool at 0x3fd8bfc0, length 2048064 bytes, 128004 blocks

Block 128003 is an AT_HEAD and eventually is passed to gc_mark_subtree.
This causes gc_mark_subtree to call ATB_GET_KIND(128004).  When block 1 is
created with a finaliser, the first byte of the finaliser table becomes
0x2, but ATB_GET_KIND(128004) reads these bits as AT_TAIL, and then
gc_mark_subtree references past the end of the heap, which happened to be
past the end of PSRAM on the esp32-s2.

The fix in this commit is to ensure there is a one-byte gap after the ATB
filled permanently with AT_FREE.

Fixes issue #7116.

Ayke van Laethem bcc827d695 py/gc: Allow the GC heap to be split over multiple memory areas.
This commit adds a new option MICROPY_GC_SPLIT_HEAP (disabled by default)
which, when enabled, allows the GC heap to be split over multiple memory
areas/regions.  The first area is added with gc_init() and subsequent areas
can be added with gc_add().  New areas can be added at runtime.  Areas are
stored internally as a linked list, and calls to gc_alloc() can be
satisfied from any area.

This feature has the following use-cases (among others):
- The ESP32 has a fragmented OS heap, so to use all (or more) of it the
  GC heap must be split.
- Other MCUs may have disjoint RAM regions and are now able to use them
  all for the GC heap.
- The user could explicitly increase the size of the GC heap.
- Support a dynamic heap while running on an OS, adding more heap when
  necessary.

Boosted performance, board.json metadata, more mimxrt, rp2, samd features

This release of MicroPython sees a boost to the overall performance of the
VM and runtime.  This is achieved by the addition of an optional cache to
speed up general hash table lookups, as well as a fast path in the VM for
the LOAD_ATTR opcode on instance types.  The new configuration options are
MICROPY_OPT_MAP_LOOKUP_CACHE and MICROPY_OPT_LOAD_ATTR_FAST_PATH.  As part
of this improvement the MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE option has
been removed, which provided a similar map caching mechanism but with the
cache stored in the bytecode, which made it not useful on bare metal ports.
The new mechanism is measured to be at least as good as the old one,
applies to more map lookups, has a constant RAM overhead, and applies to
native code as well as bytecode.

These performance options are enabled on the esp32, mimxrt, rp2, stm32 and
unix ports.  For esp32 and mimxrt some code is also moved to RAM to further
boost performance.  On stm32, performance increases by about 20% for
benchmarks that are heavy on name lookups, like misc_pystone.py and
misc_raytrace.py.  On esp32 performance can increase by 2-3x, and on mimxrt
it is up to 6x.

All boards in all ports now have a board.json metadata file, which is used
to automatically build firmware and generate a webpage for that board
(among other possibilities).  Auto-build scripts have been added for this
purpose and they build all esp32, mimxrt, rp2, samd and stm32 boards.  The
generated output is available at https://micropython.org/download.

Support for FROZEN_DIR and FROZEN_MPY_DIR has been deprecated for some time
and was finally removed in this release.  Instead of these, FROZEN_MANIFEST
can be used.  The io.resource_stream() function is also removed, replaced
by the pure Python version in micropython-lib.

The search order for importing frozen Python modules is now controlled by
the ".frozen" entry in sys.path.  This string is added by default in the
second position in sys.path.  User code should adjust sys.path depending on
the desired behaviour.  Putting ".frozen" first in sys.path will speed up
importing frozen modules.

A bug in multiple precision integers with bitwise of -0 was fixed in commit
2c139bbf4e.

The platform module has been added to allow querying the compiler and
underlying SDK/HAL/libc version.  This is enabled on esp32, mimxrt and
stm32 ports.

The mpremote tool now supports seek, flush, mkdir and rmdir on PC-mounted
filesystems.  And a help command has been added.

The documentation has seen many additions and improvements thanks (for a
second time) to the Google Season of Docs project.  The rp2 documentation
now includes a reference for PIO assembly instructions, a PIO quick
reference and a PIO tutorial.  The random and stm modules have been
documented, along with sys.settrace, manifest.py files and mpremote.  There
is also now more detail about the differences between MicroPython and
standard Python 3.5 and above.

The esp32 port sees support for ESP32-S3 SoCs, and new boards GENERIC_S3,
ESP32_S2_WROVER, LOLIN_S2_MINI, LOLIN_S2_PICO and UM_FEATHERS2NEO.  The PWM
driver has been improved and now supports all PWM timers and channels, and
the duty_u16() and duty_ns() methods, and it keeps the duty constant when
changing frequency.  The machine.bitstream() function has been improved to
use RMT, with an option to select the original bit-banging implementation.

The mimxrt port gained new hardware features: SDRAM and SD card support, as
well as network integration with a LAN driver.  The machine.WDT class was
added along with the machine.reset_cause(), machine.soft_reset(),
machine.unique_id() add machine.bitstream() functions.  DHT sensor support
was added, and f-strings were enabled.

The rp2 port now has support for networking, and bluetooth using NimBLE.
The Nina-W10 WiFi/BT driver is fully integrated and supported by the new
Arduino Nano RP2040 connect board.  I2S protocol support is added along
with a machine.bitstream() driver and DHT sensor support.  The PWM driver
had a bug fix with the accuracy of setting/getting the frequency, and the
duty value is now retained when changing the frequency.

On the samd port there is now support for the internal flash being a block
device, and for filesystems and the os module.  Pin and LED classes have
been implemented.  There are more time functions, more Python features
enabled, and the help() function is added.  SEEED_WIO_TERMINAL and
SEEED_XIAO board definitions are now available.

The stm32 port now has support for F427, F479 and H7A3(Q)/H7B3(Q) MCUs, and
new board definitions for VCC_GND_H743VI, OLIMEX_H407, MIKROE_QUAIL,
GARATRONIC_PYBSTICK26_F411, STM32H73B3I_DK.  A bug was fixed in the SPI
driver where a SPI transfer could fail if the CYW43 WiFi driver was also
active at the same time.

On the windows port the help() function has been enabled, and support for
build variants added, to match the unix port.

The zephyr port upgraded Zephyr to v2.7.0.

The change in code size since the previous release for various ports is
(absolute and percentage change in the text section):

       bare-arm:  -1520  -2.605%
    minimal x86:  -2256  -1.531%
       unix x64:   -457  -0.089%
    unix nanbox:   -925  -0.204%
          stm32:   +312  +0.079% PYBV10
         cc3200:   -176  -0.096%
        esp8266:   +532  +0.076% GENERIC
          esp32: +27096  +1.820% GENERIC
            nrf:   -212  -0.121% pca10040
            rp2:  +9904  +2.051% PICO
           samd: +35332 +33.969% ADAFRUIT_ITSYBITSY_M4_EXPRESS

The changes that dominate these numbers are:
- bare-arm, minimal: use of new MICROPY_CONFIG_ROM_LEVEL_MINIMUM option and
  subsequent disabling of remaining optional features
- unix, cc3200, nrf: general code size reductions of the core
- stm32: performance improvements, addition of platform module
- esp8266: enabling f-strings
- esp32: use of -O2 instead of -Os
- rp2: machine.I2S and other new hardware features
- samd: filesystem support and other new hardware features

Laurens Valk 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.

Jeff Epler 15133cbf59 gc.c: Avoid valgrind false positives.
When you wish to use the valgrind memory analysis tool on micropython,
you can arrange to define MICROPY_DEBUG_VALGRIND to enable use of
special valgrind macros. For now, this only fixes `gc_get_ptr`
so that it never emits the diagnostic "Conditional jump or move depends
on uninitialised value(s)".

Damien George 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).
