This is the minimum C interface to allow a modem driver to be built in
Python. Interface is simple, with the intention that the micropython-lib
driver is the main (only) consumer of it.

These files all use decorators (@asm_thumb, @asm_pio) that add names to the
function scope, that the linter cannot see.
It's useful to clear them in the file not in pyproject.toml as example code
will be copied and adapted elsewhere, and those developers may also use
Ruff (we hope!)

It should be that:

This is difficult to implement on cmake-based ports, and having the list
of variants in mpconfigboard.{cmake,mk} duplicates information that's
already in board.json.
This removes the existing query-variants make target from stm32 & rp2
and the definition of BOARD_VARIANTS from the various board files.
Also renames the cmake variable to MICROPY_BOARD_VARIANT to match other
variables such as MICROPY_BOARD. The make variable stays as
BOARD_VARIANT.

Also shrinks the "prefer internal" threshold to 8KB, any allocation larger
than this will try PSRAM first.
Change the mbedTLS config to use regular malloc() as well, instead of
internal only. The default is set to internal-only due to to potential
physical security issue of readout via PSRAM on the original ESP32.
However, as MicroPython runs from plaintext flash and all other context is
in the MP heap of PSRAM then it's hard to see how worsens physical security
for MP.

When set, the split heap is automatically extended with new areas on
demand, and shrunk if a heap area becomes empty during a GC pass or soft
reset.
To save code size the size allocation for a new heap block (including
metadata) is estimated at 103% of the failed allocation, rather than
working from the more complex algorithm in gc_try_add_heap(). This appears
to work well except in the extreme limit case when almost all RAM is
exhausted (~last few hundred bytes). However in this case some allocation
is likely to fail soon anyhow.
Currently there is no API to manually add a block of a given size to the
heap, although that could easily be added if necessary.

An SSL stream can only handle CLOSE and POLL ioctls. Other ones do not
make sense, or at least it doesn't make sense to pass the ioctl request
directly down to the underlying stream.
In particular MP_STREAM_GET_FILENO should not be passed to the underlying
stream because the SSL stream is not directly related to a file descriptor,
and the SSL stream must handle the polling itself.

A previous commit removed the unix-specific select module implementation
and made unix use the common one.
This commit adds an optimisation so that the system poll function is used
when polling objects that have a file descriptor. With this optimisation
enabled, if code registers both file-descriptor-based objects, and non-
file-descriptor-based objects with select.poll() then the following occurs:
- the system poll is called for all file-descriptor-based objects with a
timeout of 1ms
- then the bare-metal polling implementation is used for remaining objects,
which calls into their ioctl method (which can be in C or Python)
In the case where all objects have file descriptors, the system poll is
called with the full timeout requested by the caller. That makes it as
efficient as possible in the case everything has a file descriptor.
Benefits of this approach:
- all ports use the same select module implementation
- the unix port now supports polling of all objects and matches bare metal
implementations
- it's still efficient for existing cases where only files and sockets are
polled (on unix)
- the bare metal implementation does not change
- polling of SSL objects will now work on unix by calling in to the ioctl
method on SSL objects (this is required for asyncio ssl support)
Note that extmod/vfs_posix_file.c has poll disable when the optimisation is
enabled, because the code is not reachable when the optimisation is used.

The unix port has a custom select module which only works with objects that
have a file descriptor, eg files and sockets. On the other hand, bare
metal ports use the common extmod/modselect.c implementation of the select
module that supports polling of arbitrary objects, as long as those objects
provide a MP_STREAM_POLL in their ioctl implementation (which can be done
in C or Python).
This commit removes the unix-specific code and makes unix use the common
one provided by extmod/modselect.c instead. All objects with file
descriptors implement MP_STREAM_POLL so they continue to work.
