The changes in this commit are:
- Add an interface for pin open-drain mode.
- Improve ticks_us() by using the us-counter.
- Improve ticks_cpu() by using the CPU's SysTick.
Clock settings:
- GCLK0: 48 MHz (SAMD21) or 120 MHz(SAMD51).
- GCLK1: 32768 Hz for driving the PLL.
- GCLK2: 48 MHz for tzhe peripheral clock.
- GCLK3: 1 MHz (SAMD21) or 8 MHz (SAMD51) for the µs ticks timer.
- GCLK8: 1 kHz for WDT (SAMD21 only).
If a 32 kHz crystal is present, it will be used as clock source. Otherwise
the DFLL48M in open-loop mode is used.
GCLK0 for SAM51 can be changed between 48 MHz and 200 MHz. The specified
range is 96 MHz - 120 MHz.
These two boards are used for testing, so it is favorable to have them
added early.
The full test set is:
- ADAFRUIT_FEATHER_M4_EXPRESS: SAMD51 with 32kHz crystal.
- ADAFRUIT_ITSYBITSY_M0_EXPRESS: SAMD21 without crystal.
- ADAFRUIT_ITSYBITSY_M4_EXPRESS: SAMD51 without crystal.
- SEEED_XIAO: SAM21 with 32kHz crystal.
Fixes in this commit are:
- Make --follow the default for "run" (accidentally changed in 68d094358).
- Add help strings for "repl": --capture --inject-file --inject-code
- Update help strings for "run".
- Fix encoding for --inject-code (accidentally broken in 68d094358).
- Remove ability to --no-follow for "eval". It was there previously because
it shared the same code path with "exec" and "run", but makes no sense
for "eval", so might as well remove.

Auto DMA channel is supported in IDF v4.4, and is required to be used on S3
chips, so use this simpler configuration option where possible.

Tweak the existing codeformat.py and verifygitlog.py to allow them to be
easily called by pre-commit.
(This turned out to be easier than using any existing pre-commit hooks,
without making subtle changes in the formatting.)

Uncrustify versions are not mutually compatible:
1. Version 0.73 or newer produce slightly different formatting. It may be
possible to tweak these by adding more config items, but this will cause
older versions to error out with 'Unknown option'.
2. Version 0.75 prints a range of deprecation warnings due to config file
changes, and returns a non-zero exit code. These are actually fixable
as most are the default value, and pp_indent has changed from 'true' to '1'
which is backwards compatible. However issue 1 remains, so probably better
to have it fail explicitly.

This supports the same package sources as the new `mip` tool.
- micropython-lib (by name)
- http(s) & github packages with json description
- directly downloading a .py/.mpy file
The version is specified with an optional `@version` on the end of the
package name. The target dir, index, and mpy/no-mpy can be set through
command line args.

No functional change other than to allow slightly more flexibility in how
--foo arguments are specified.
This removes all custom handling for --foo args in all commands and
replaces it with per-command argparse configs.

No functional change.
This makes each built-in command defined by just a handler method and
simplifies a lot of the logic around tracking the board state.

This has a fairly dramatic (nearly 3x on a 6-core machine) speedup for docs

Needed to be updated to use build/mpy-cross.
Also fixes some other issues in the Python wrapper:
- Rename find_mpy_cross_binary to _find_mpy_cross_binary
- Fix passing of -march arg.
- Decode stdout from subprocess.
- Print stdout from mpy-cross in __main__.py.

Changes in this new library version are:
- Add L1 HAL at v1.10.3.
- H7_HAL/rcc_ex: Add SPI45 to HAL_RCCEx_GetPeriphCLKFreq.
- L4_HAL/gpio_ex: Add #define for GPIO_AF14_TIM2 on L4P5/L4Q5.
- F4_HAL/i2c: Fix I2C frequency calculation macros.
- L1_HAL/utils: Fix compile error when USE_HAL_DRIVER is defined.
Allows optimisation of cases like:
import micropython
_DEBUG = micropython.const(False)
if _DEBUG:
print('Debugging info')
Previously the 'if' statement was only optimised out if the type of the
const() argument was integer.
The change is implemented in a way that makes the compiler slightly smaller
(-16 bytes on PYBV11) but compilation will also be very slightly slower.
As a bonus, if const support is enabled then the compiler can now optimise
const truthy/falsey expressions of other types, like:
while "something":
pass
... unclear if that is useful, but perhaps it could be.

The call to invoke_irq_handler_run() always needs to run in a protected NLR
context, to catch exceptions from the Python handler, and the m_new's (and
also mp_local_alloc when PYSTACK is enabled). With
MICROPY_PY_BLUETOOTH_USE_SYNC_EVENTS_WITH_INTERLOCK enabled there was
already an explicit nlr_push, and that is now used in all cases.
Without this change, on stm32 (for example), the callbacks from the BLE
stack to invoke_irq_handler() were made via static scheduled nodes which do
not have any NLR protection, and hence would lead to a hard fault (uncaught
NLR) if an exception was raised in the Python BLE IRQ handler. This was a
regression introduced by 8045ac07f5, which is
fixed by this commit.

The calls to m_new and m_del require an exclusive uPy (really a GC)
context. In particular these functions cannot be called directly from a

This uses the frozentest.mpy that is also used by ports/minimal.
Also fixes two bugs that these new tests picked up:
- File extension matching in manifestfile.py.
- Handling of freeze_mpy results in makemanifest.

frozentest.mpy was previously duplicated in ports/minimal and
ports/powerpc.
This needs to be re-generated on every .mpy version increase, so might as
well just have a single copy of it.

Prevent handle leaks when file objects aren't closed explicitly and
fix some MICROPY_CPYTHON_COMPAT issues: this wasn't properly adhered
to because #ifdef was used so it was always on, and closing files
multiple times should be avoided unconditionally.
This improves error messages in mpy-cross:
- When loading a .py file that doesn't exist (or can't be opened) it now
includes the filename in the OSError.
- When saving a .mpy file that can't be opened it now raises an exception
(prior, it would silently fail), and includes the filename in the
OSError.

This matches class `__dict__`, and is similarly gated on
MICROPY_CPYTHON_COMPAT. Unlike class though, because modules's globals are
actually dict instances, the result is a mutable dictionary.
