Switch SAMD21 ticks to PER event
The EVSYS is used to generate an interrupt from the event. This
simplifies timing used in pulseio that conflicted with the
auto-reload countdown.

Fix a couple fake sleep bugs on nrf and esp
On ESP ctrl-c during fake sleep will now stop the sleep. A crash
on real deep sleep is now fixed as well. (Exception string saving
was crashing on reading the deep sleep exception.) Fixes #4010

This also fixes nRF fake sleep after the first time. The internal

    lib/memzip          -> shared/memzip
    lib/netutils        -> shared/netutils
    lib/timeutils       -> shared/timeutils
    lib/upytesthelper   -> shared/upytesthelper

All files in lib/embed/ have been moved to shared/libc/.

lib/mp-readline has been moved to shared/readline.

lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.

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).

From a version numbering point of view this is a downgrade (2.17.0 ->
2.16.x).  However the latest commit for version 2.17.0 is from March 2019
and no further minor release happened after 2.17.0.  This version is EOL.
2.16.x though is still actively maintained as a long term release, hence
security and stability fixes are still being backported, including
compatibility with upcoming compiler releases.

Also found a race condition between timer_disable and redraw, which
would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable
or put a delay or print inside it.  That's what pausing inside reconstruct
fixes.

So that the "right timer" can be chosen, `timer_allocate` now gets the `self`
pointer.  It's guaranteed at this point that the pin information is accurate,
so you can e.g., find a PWM unit related to the pins themselves.
This required touching each port to add the parameter even though it's
unused everywhere but raspberrypi.

Damien George bb24c69b90 lib/utils/pyexec: Add stdin-reader on raw REPL with flow control.
Background: the friendly/normal REPL is intended for human use whereas the
raw REPL is for computer use/automation.  Raw REPL is used for things like
pyboard.py script_to_run.py.  The normal REPL has built-in flow control
because it echos back the characters.  That's not so with raw REPL and flow
control is just implemented by rate limiting the amount of data that goes
in.  Currently it's fixed at 256 byte chunks every 10ms.  This is sometimes
too fast for slow MCUs or systems with small stdin buffers.  It's also too
slow for a lot of higher-end MCUs, ie it could be a lot faster.

This commit adds a new raw REPL mode which includes flow control: the
device will echo back a character after a certain number of bytes are sent
to the host, and the host can use this to regulate the data going out to
the device.  The amount of characters is controlled by the device and sent
to the host before communication starts.  This flow control allows getting
the maximum speed out of a serial link, regardless of the link or the
device at the other end.

Also, this new raw REPL mode parses and compiles the incoming data as it
comes in.  It does this by creating a "stdin reader" object which is then
passed to the lexer.  The lexer requests bytes from this "stdin reader"
which retrieves bytes from the host, and does flow control.  What this
means is that no memory is used to store the script (in the existing raw
REPL mode the device needs a big buffer to read in the script before it can
pass it on to the lexer/parser/compiler).  The only memory needed on the
device is enough to parse and compile.

Finally, it would be possible to extend this new raw REPL to allow bytecode
(.mpy files) to be sent as well as text mode scripts (but that's not done
in this commit).

Some results follow. The test was to send a large 33k script that contains
mostly comments and then prints out the heap, run via pyboard.py large.py.

(the big blob of used memory is the large script).

Same but with this PR:

$ ./pyboard.py large.py

       (381 lines all free)

The only thing in RAM is the compiled script (and some other unrelated
items).

Time to download before this PR: 1438ms, data rate: 230,799 bits/sec.

Time to download with this PR: 119ms, data rate: 2,788,991 bits/sec.

So it's more than 10 times faster, and uses significantly less RAM.

Results are similar on other boards. On an stm32 board that connects via
UART only at 115200 baud, the data rate goes from 80kbit/sec to
113kbit/sec, so gets close to saturating the UART link without loss of
data.

The new raw REPL mode also supports a single ctrl-C to break out of this
flow-control mode, so that a ctrl-C can always get back to a known state.
It's also backwards compatible with the original raw REPL mode, which is
still supported with the same sequence of commands.  The new raw REPL
mode is activated by ctrl-E, which gives an error on devices that do not
support the new mode.

We previously had the _changes_ of jepler/fix-cpy-3184 and
hierophect/cpy-timer-allocator but not their merge commits.

The only other changes in protomatter were one formatting change in the
core, plus several Arduino sketches.  So this should make no practical
difference for CPy.

Damien George 8f20cdc353 all: Rename absolute time-based functions to include "epoch".
For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values.  And
different ports may use a different Epoch.

To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").

Along with this rename, the following things have changed:

- mp_hal_time_ns() is now specified to return the number of nanoseconds
  since the Epoch, rather than since 1970 (but since this is an internal
  function it doesn't change anything for the user).

- littlefs timestamps on the esp8266 have been fixed (they were previously
  off by 30 years in nanoseconds).

Otherwise, there is no functional change made by this commit.

Jim Mussared 23109988c2 stm32/uart: Allow static IRQ handler registration.
This will allow the HCI UART to use a non-heap mp_irq_obj_t, which avoids
needing to make a root pointer for it.

Damien George 3ff7079277 lib/utils/mpirq: Add mp_irq_init func, and clean up unused init method.
mp_irq_init() is useful when the IRQ object is allocated by the caller.

The mp_irq_methods_t.init method is not used anywhere so has been removed.

Jeff Epler 2f120c70ee rgbmatrix: recover gracefully from allocation errors
e.g., allocating a 192x32x6bpp matrix would be enough to trigger this
reliably on a Metro M4 Express using the "memory hogging" layout.
Allocating 64x32x6bpp could trigger it, but somewhat unreliably.

There are several things going on here:
 * we make the failing call with interrupts off
 * we were throwing an exception with interrupts off
 * protomatter failed badly in _PM_free when it was partially-initialized

Incorporate the fix from protomatter, switch to a non-throwing malloc
variant, and ensure that interrupts get turned back on.

This decreases the quality of the MemoryError (it cannot report the size
of the failed allocation) but allows CircuitPython to survive, rather
than faulting.

Jeff Epler e9bc8e892b pyexec: Handle a ctrl-c that comes in "very late"
In relatively unusual circumstances, such as entering `l = 17 ** 17777`
at the REPL, you could hit ctrl-c, but not get KeyboardInterrupt.
This can lead to a condition where the display would stop updating (#2689).

Jeff Epler c0b32976e8 libm: rem_pio2: Reduce size of static array
This array was of 32-bit values, but the entries were only ever
in the 0-255 range.  Convert to uint8_t.

Testing performed: The result of the sum-of-sin was unchanged

Jeff Epler d3fb6c96da libm: ef_rem_pio2.c: Save ROM-tables at the expense of speed
This function computes the remainder of a value `x` modulo pi/2, to high
precision.

It does this by dividing the flotaing point values into several ranges
by magnitude, and applies successively slower but more accurate algorithms.

The last two steps, one covering values up to around 2^7 * pi/2
(called "medium size") and a final one covering all possible float values,
require big tables.

By eliminating the "medium size" case, a table and some code are removed
from the binary.  This makes some cases take longer, but saves hundreds
of bytes.  It does _NOT_ affect the result, only the speed.

```
