So that SDRAM can be used as the heap on ARDUINO_PORTENTA_H7, for example.

Fixes issue #9087.

If mboot is built with support for packing (signing/encryption) it needs up
to 32KiB.  So for simplicity increase the mboot region to 32KiB
unconditionally for WB55 boards (custom WB55 board configurations can still
provide their own linker scripts to override this).

Rather than having the autobuild know about the particular variants, have
the mpconfigboard.mk describe them and make autobuild discover them
automatically.

Adds a "query-variants" target to stm32/Makefile to allow the set of
possible variants to be queried.

Removes pybv3 from the autobuild as this isn't use by the downloads page.

Not safe to use mp_hal_delay_ms before boot if threading is enabled,
because threading will not have been initialised, and
MICROPY_EVENT_POLL_HOOK assumes threading is initialised.

HAL_Delay doesn't call MICROPY_EVENT_POLL_HOOK, but is still
power-efficient like mp_hal_delay_ms (unlike mp_hal_delay_us).

Fixes #7816.

It has been about 8 years since support for this chip was added.  Reasons
to remove it are:
- It is no longer easy to obtain this part.
- There are now many other options for WiFi.
- It's not a good use of developer time to maintain it.

Updated some of the CPython feature differences:
- Updated status of some features.
- Added CSS to fix table widths to 100% and word wrap.
- Specified explicit table column ratios to improve layout appearance.
- Added missing references to anchors.
- Better consistency with use of formatting and case.

The existing non-Docker instructions are basically impossible to follow
because the esp-open-sdk does not compile.  Update these instructions to
use the exact toolchain that our CI uses.

Also split the Docker from non-Docker instructions, to avoid confusion
about which commands need to be prefixed.

Previously the desired output type was specified.  Now make the type part
of the function name.  Because this function is used in a few places this
saves code size due to smaller call-site.

This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).

This saves ~140 bytes on PYBV11.

Now that we have `mp_obj_new_str_type_from_vstr` (private helper used by
objstr.c) split from the public API (`mp_obj_new_str_from_vstr`), we can
enforce a unicode check at the public API without incurring a performance
cost on the various objstr.c methods (which are already working on known
unicode-safe strings).

There don't seem to be many changes going from v2.1.2 to v2.1.3 of lwIP.
Mostly they are:
- IPv6 fixes and improvements
- changes to apps and other code that MicroPython doesn't use
- comments and tests
- minor bug fixes

In particular there doesn't look to be any change to the API of any
function used by MicroPython.

Network multi tests pass on PYBD_SF2 and PYBD_SF6.  PYBD_SF2, PYBD_SF6 and
PICO_W have unchanged iperf3 performance.  Similar results for networking
on the mimxrt port.

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.

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.

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.

Useful when more detail is needed for an OSError associated with a file.

Signed-off-by: Damien George <damien@micropython.org>

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.

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.

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.

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.
