Re-enable some features required for the board to still build and the lora
driver to run.

This board only has 192KB of flash total, so default stm32 build is very
close to the limit.

Before:

After:

LINK build-B_L072Z_LRWAN1/firmware.elf

Allow boards to define their own additional USB callbacks.

Signed-off-by: Luca Burelli <[email protected]>

On targets that provide a reference TinyUSB implementation, like ESP32,
the SDK already defines and implements standard callback functions such
as tud_cdc_line_state_cb(). This causes a symbol clash when enabling
shared implementations like the MicroPython 1200 touch functionality.

To avoid this symbol clash, add an optional macro to allow ports to
use a different function name in the shared implementation.

The EXTRA_COMPONENT_DIRS variable is a list so adding a directory so should
be done via append, not set.  This enables boards to use other components

The compression algorithm implemented in this commit uses much less memory
compared to the standard way of implementing it using a hash table and
large look-back window.  In particular the algorithm here doesn't allocate
hash table to store indices into the history of the previously seen text.
Instead it simply does a brute-force-search of the history text to find a
match for the compressor.  This is slower (linear search vs hash table
lookup) but with a small enough history (eg 512 bytes) it's not that slow.
And a small history does not impact the compression too much.

To give some more concrete numbers comparing memory use between the
approaches:

- Standard approach: inplace compression, all text to compress must be in
  RAM (or at least memory addressable), and then an additional 16k bytes
  RAM of hash table pointers, pointing into the text

- The approach in this commit: streaming compression, only a limited amount
  of previous text must be in RAM (user selectable, defaults to 512 bytes).

To compress, say, 1k of data, the standard approach requires all that data
to be in RAM, plus an additional 16k of RAM for the hash table pointers.
With this commit, you only need the 1k of data in RAM.  Or if it's
streaming from a file (or elsewhere), you could get away with only 256
bytes of RAM for the sliding history and still get very decent compression.

In summary: because compression takes such a large amount of RAM (in the
standard algorithm) and it's not really suitable for microcontrollers, the
approach taken in this commit is to minimise RAM usage as much as possible,
and still have acceptable performance (speed and compression ratio).

  Outbuf.

This provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.

This class can be used directly, and also can be used from Python to
implement (via io.BytesIO) zlib.decompress and zlib.compress, as well as
gzip.GzipFile.

When MICROPY_SCHEDULER_STATIC_NODES is enabled, the logic is unchanged.

When MICROPY_SCHEDULER_STATIC_NODES is disable, sched_state is now always
initialised to MP_SCHED_IDLE when calling mp_init().  For example, the use
of mp_sched_vm_abort(), if it aborts a running scheduled function, can lead
to the scheduler starting off in a locked state when the runtime is
restarted, and then it stays locked.  This commit fixes that case by
resetting sched_state.

This changes the ESP32 WDT implementation to use a custom handle so that it
becomes possible to reset the WDT from a thread.

By default esp_task_wdt_add subscribes the task_id of the current task.
That means that if we're running in a different task we are unable to reset
the WDT, which prevents feeding the WDT from a thread directly, or even
from a timer (which may randomly run in a different task when there's
multiple threads).

As an added bonus, the name we set makes the error clearly specify that it
was the user-specified WDT that reset the chip.

While cyw43 is deinitialized, an interrupt occurs.  That is handled with
these lines: ports/rp2/mpnetworkport.c#L59-L61 and as pendsv is disabled
while in network code, the poll function then just waits there.

When deinit has finished, the poll func is executed, but skipped:
src/cyw43_ctrl.c#L222-L225 this skips the `CYW43_POST_POLL_HOOK` which
would re-enable interrupts, but also reset `cyw43_has_pending`.

And in that state, the lightsleep code, will skip sleeping as it thinks
there is a network packet pending to be handled.

With this change applied, lightsleep works as expected when the wifi chip
is enabled, and when it's powered off.

iobase_ioctl expects that an ioctl method must return an integer, and will
raise otherwise.

This was tripping up aioble on Unix, where the new hybrid modselect.c
implementation will attempt to extract a file descriptor from the pollable
via ioctl(MP_STREAM_GET_FILENO).

However, ThreadSafeFlag's ioctl only supported MP_STREAM_POLL, and returned
None otherwise.

This makes it return `-1` (to match tests/extmod/select_poll_custom.py). It
should probably be `-22` (corresponding to MP_EINVAL), but the value is
never checked, and MP_EINVAL can be a different value on different ports.

Prior to this commit, BTstack would only be notified of sent UART data when
the mp_bluetooth_hci_poll() function was called for some other reason, eg
because of incoming data over UART.  This is highly suboptimal.

With this commit, BTstack is now notified immediately after UART data has
been sent out.  This improves the multi_bluetooth/perf_gatt_char_write.py
performance test by about a factor of 10x for write-without-response, and
about 4x for write-with-response (tested on LEGO_HUB_NO6 as instance1).
