Otherwise, a very deeply nested regular expression like
re.compile("(" * 65536)
can exhaust the host stack during the compile phase. This turns
that into a `RuntimeError: maximum recursion depth exceeded`
instead.
This crash was found via fuzzing.

This is 0.19.0 plus the following changes:
- remove obsolete dcd_esp32sx
- fix for HID stylus descriptor and HID example
- typos, docs and generator scripts
- MTP fix
- DWC2 enumeration when EP0 size=8
- DWC2 fix for EP0 IN
- stm32 FSDEV IRQ remapping fix
- DWC2 ZLP fix
The reason we need the extra 24 commits is due to a bug with TinyUSB's
handling of zero-length-packets in the DWC2 (Synopsis) backend, which
affects the stm32 port. That's fixed by

The official mcux-sdk follows a slightly different structure to the
current nxp_sdk submodule, with many drivers moved to a common location.
To ease updating the newer versions of the SDK and/or add new families
the nxp_sdk submodule has been updated to follow the structure of
mcux-sdk, just trimmed down to families used here to considerably
reduce the size.

Libffi is updated to the latest stable version (v3.4.6) as the version
of libffi that was linked by the repository predates the introduction of
RISC-V processors (both 32 and 64 bits).
This is necessary as the packaged version of libffi used by the CI for
RISC-V 64 turned out to simply not work correctly, whilst a source-built
version of libffi worked just fine.

With the recent qemu (d9a0fdda9a and
0426934969) and zephyr
(05cad7b56f) changes to how their tests are
run, two things became unused:
- The tinytest framework, which embedded a set of tests and their expected
output within firmware, so these tests could be run stand-alone.
- The `--write-exp` and `--list-tests` options to `tests/run-tests.py`,
which were needed primarily to generated the expected test output for
tinytest (also the associated `tests/run-tests-exp.py/.sh` scripts are
now unused).
This commit removes the tinytest component and all its helper code. This
eliminates a maintenance burden.

fdilibm was originally meant to see _IEEE_LIBM defined from outside the
libm code, not it being hardcoded in. Picolibc assumes this assumption
holds true and attempts to define itself, conflicting with the existing
definition.

Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to
define. Its redefinition breaks compilation with picolibc as the
target's libc, since it defines said symbol in math.h before the libm
define is evaluated by the compiler.
In its place, there is a check to make sure floating point type sizes
are what are expected to be, triggering a compilation error if those
assumptions are no longer valid.

This updates the berkeley-db-1.xx submodule URL to a repository hosted
under the micropython organisation, and makes the following changes:
- Moves the berkeley-db header files to a single directory within the
submodule, and references all these headers with a much fuller path,
which prevents symbol clashes (eg with esp32 and queue.h).
- Removes unused/non-working files from berkeley-db, which removes all
symlinks in that repo (symlinks don't play well under Windows).
- Allows injecting an external configuration header into berkeley-db, so
the configuration doesn't have to be provided by -Dxx=yy flags to the
compiler (and possibly clashing with other symbols).
- Removes the advertising clause from the BSD 4-clause license of
berkeley-db (see relevant commit and README.Impt.License.Change for
details).

OpenAMP framework provides a standard inter processor communications
infrastructure for RTOS and bare metal environments. There are 3 major
components in OpenAMP: libmetal, remoteproc and RPMsg. libmetal provides
abstraction of the low-level underlying hardware, remoteproc is used for
processor Life Cycle Management (LCM) like loading firmware, starting,
stopping a core etc., and RPMsg is a bus infrastructure that enables Inter
Processor Communications (IPC) between different cores.
