Damien George 335002a4c0 extmod/uasyncio: Allow task state to be a callable.
This implements a form of CPython's "add_done_callback()", but at this
stage it is a hidden feature and only intended to be used internally.

MikeTeachman 1f6cb8f047 mixmrt/machine_i2s: Add I2S protocol support.
This commit adds support for machine.I2S on the mimxrt port.  The I2S API
is consistent with the existing stm32, esp32, and rp2 implementations.

I2S features:
- controller transmit and controller receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequencies from 8kHz to 48kHz
- 3 modes of operation:
  - blocking
  - non-blocking with callback
  - uasyncio
- configurable internal buffer
- optional MCK

Tested with the following development boards:
- MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK
- Teensy 4.0, Teensy 4.1
- Olimex RT1010
- Seeed ARCH MIX

Tested with the following I2S hardware peripherals:
- UDA1334
- GY-SPH0645LM4H
- WM8960 codec on board the MIMXRT boards and separate breakout board
- INMP441
- PCM5102
- SGTL5000 on the Teensy audio shield

Damien George b312a7abf5 py/builtinimport: Alias sys to usys if import weak links aren't enabled.
The sys module should always be available (if it's compiled in), eg to
change sys.path for importing.  So provide an explicit alias from "sys" to
"usys" so that "import sys" can always work.

Damien George 6d11c69983 py: Change jump-if-x-or-pop opcodes to have unsigned offset argument.
These jumps are always forwards, and it's more efficient in the VM to
decode an unsigned argument.  These opcodes are already optimised versions
of the sequence "dup-top pop-jump-if-x pop" so it doesn't hurt generality
to optimise them further.

Damien George 538c3c0a55 py: Change jump opcodes to emit 1-byte jump offset when possible.
This commit introduces changes:

- All jump opcodes are changed to have variable length arguments, of either
  1 or 2 bytes (previously they were fixed at 2 bytes).  In most cases only
  1 byte is needed to encode the short jump offset, saving bytecode size.

- The bytecode emitter now selects 1 byte jump arguments when the jump
  offset is guaranteed to fit in 1 byte.  This is achieved by checking if
  the code size changed during the last pass and, if it did (if it shrank),
  then requesting that the compiler make another pass to get the correct
  offsets of the now-smaller code.  This can continue multiple times until
  the code stabilises.  The code can only ever shrink so this iteration is
  guaranteed to complete.  In most cases no extra passes are needed, the
  original 4 passes are enough to get it right by the 4th pass (because the
  2nd pass computes roughly the correct labels and the 3rd pass computes
  the correct size for the jump argument).

This change to the jump opcode encoding reduces .mpy files and RAM usage
(when bytecode is in RAM) by about 2% on average.

The performance of the VM is not impacted, at least within measurment of
the performance benchmark suite.

Code size is reduced for builds that include a decent amount of frozen
bytecode.  ARM Cortex-M builds without any frozen code increase by about
350 bytes.

David Lechner e7f6b9f4f7 tools/gen-cpydiff: Skip Black fmt comments.
Since cpydiff is code used as documentation, there are cases where we may
want to use Black's `fmt: on/off/skip` comments to avoid automatic
formatting.  However, we don't want these comments to be distracting in the
generated documentation.

This rewrites the code to omit these comments when generating the docs.

Jonathan Hogg 7684c996bc esp32/machine_pin: Add new hold keyword argument and remove PULL_HOLD.
The current pull=Pin.PULL_HOLD argument doesn't make a lot of sense in the
context of what it actually does vs what the ESP32 quickref document says
it does.

This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init().  Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.

Fixes issue #8283, and see also #8284.
