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

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.

frozentest.mpy was previously duplicated in ports/minimal and

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.

The intent is to allow us to make breaking changes to the native ABI (e.g.
changes to dynruntime.h) without needing the bytecode version to increment.
With this commit the two bits previously used for the feature flags (but
now unused as of .mpy version 6) encode a sub-version. A bytecode-only
.mpy file can be loaded as long as MPY_VERSION matches, but a native .mpy
(i.e. one with an arch set) must also match MPY_SUB_VERSION. This allows 3
additional updates to the native ABI per bytecode revision.
The sub-version is set to 1 because the previous commits that changed the
layout of mp_obj_type_t have changed the native ABI.

The check for make_new (i.e. used to determine something's type) is now
more complicated due to the slot access. This commit changes the inlining
of a few frequently-used helpers to overall improve code size and
performance.
Instead of being an explicit field, it's now a slot like all the other
methods.
This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.
This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
to a mp_getiter_iternext_custom_t instance, which then defines both
getiter and iternext.
And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.
Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

In all cases other than where you have a native base with a protocol, it
now fits into 4 GC blocks (like it did before the slots representation).

The existings mp_obj_type_t uses a sparse representation for slots for the
capability methods of the type (eg print, make_new). This commit adds a
compact slot-index representation. The basic idea is that where the
mp_obj_type_t struct used to have 12 pointer fields, it now has 12 uint8_t
indices, and a variable-length array of pointers. So in the best case (no
fields used) it saves 12x4-12=36 bytes (on a 32-bit machine) and in the
common case (three fields used) it saves 9x4-12=24 bytes.
Overall with all associated changes, this slot-index representation reduces
code size by 1000 to 3000 bytes on bare-metal ports. Performance is
marginally better on a few tests (eg about 1% better on misc_pystone.py and
misc_raytrace.py on PYBv1.1), but overall marginally worse by a percent or
so.
See issue #7542 for further analysis and discussion.
