This commit documents and verifies the current absence of
`__init_subclass__` functionality, in anticipation of a possible future
PEP487 'metaclasses lite' patch.

The main `core_class_initsubclass.py` test verifies if the method is
automatically called, while the other three verify other orthogonal
properties it should have: if the method is an implicit classmethod; if
MicroPython supplies the base case for the usual recursive function body
the PEP encourages; and if kwargs inheritance parameters work correctly.

The calls signature for gc_malloc was changed in
5ed578e5b4, without cleaning up existing
code on the rationale that the previous bool is automatically converted
to an int with the same meaning.

This commit goes back and cleans up existing invocations to make their
behavior more readable in a modern context.

9e89c752cb py/makeversionhdr.py: Always abbreviate Git hashes to same length.
The Git hash is embedded in the version number.  The hash is abbreviated by
Git.  This commit changes the length of the Git hash abbreviation to a
fixed number, so that the length of the version string no longer varies
based on external factors (it can still vary, but will now be at least 10
characters).

This change is made because builds of the same MicroPython commit on
multiple machines were sometimes giving a version string with different
lengths, eg due to commits on other local branches having a clashing
abbreviated hash.  This change may also help the code size report to be
more consistent, because it will less often be impacted by random changes
in the version string length, at the cost of always being a few bytes
longer.

1aaf6eddd8 tools/mpremote: Don't apply Espressif DTR/RTS quirk to TinyUSB CDC dev.
The DTR quirk workaround from dea949e86 is needed for the Espressif
Serial/JTAG device, but not for TinyUSB - in fact DTR must be set for
TinyUSB to correctly determine if the serial port is open (and leads to
issues with lost bytes otherwise).

371db85c8e esp32/machine_uart: Convert machine.UART objects to static instances.
Makes machine.UART objects static instances (similar to other ports), adds
machine_uart_deinit_all() function for cleanup on soft reset.

- Fixes the case where the OS-level uart_event_task is leaked
  (along with 2KB of heap) when a UART object is garbage collected
  (including after a soft reset).

- Fixes hard fault if a previous UART irq() fires after the UART object is
  garbage collected (including after a soft reset), but before any new UART
  object is instantiated for the same UART number.

- Constructing multiple UART objects for the same UART now returns the
  same instance multiple times, not different instances.

- Was also able to streamline deinit/init to only install the driver once,
  rather than install-with-defaults/uninstall/reinstall.

Alternative would be to add a finaliser, but this is more consistent
with how most other UART objects are implemented.

a43e38544b shared/tinyusb/mp_usbd_cdc: Rewrite USB CDC TX loop.
This is related to the previous commit (where due to the new config flag
this loop could end up stuck indefinitely if the USB host was
disconnected). The previous loop could maybe still get stuck if the
low-level USB state and the high-level USB state got out of sync. (Not
clearly possible, but hard to say definitely not possible.)

To be "belts and braces" careful:

- Always run mp_usbd_task() each time around the loop to progress the
  state.
- Always evaluate the timeout if we fail to write anything to the FIFO.

3ec2e367de shared/tinyusb: Fix hang from new tx_overwritabe_if_not_connected flag.
This flag is in the main branch of TinyUSB, included in Espressif since
their v0.18.0~3 component release (but it's not actually in TinyUSB v0.18.0
release).

Setting the flag is needed for the USB device not to block waiting for
space in the FIFO if the host is disconnected.

8d5a8892d2 esp32: Add IDF Component Lockfiles to git repo.
This is recommended by Espressif, and it's the only way to ensure
everyone builds the same set of component versions.

The awkward part is that updating the ESP-IDF version will churn a line
in each of these files (and possibly other changes).

Adds a build-time check for lock file changes, which is either a warning or
a hard error depending on the value of MICROPY_MAINTAINER_BUILD
flag (introduced in previous commit).

This commit fixes the build issues in the ESP32 port that arise when
explicitly disabling USB CDC support.

The USB support code gated the USB serial number retrieval behind the
USB CDC support definition, even though all USB devices must be able to
be queried for their serial number.

This commit fixes the linking issues in the RP2 port that arise when
explicitly disabling USB CDC support.

The console input ringbuffer needs to be made available if dupterm
support is enabled, and the console character input function would
always attempt to read from the input ringbuffer even if CDC support is
disabled and the console isn't bound to any UART.

A fast host (eg Mac M4) may request the status for the SET_ADDRESS before
TinyUSB gets to process it.  This is because TinyUSB does not handle events
inside the USB ISR, rather it waits for the top-level thread to process
them.  Fix that by setting the USB device address as soon as
TUSB_REQ_SET_ADDRESS comes in.

This patch follows the corresponding upstream fix:

5bafb0bf68 tests: Convert all machine.UART tests to use target_wiring.
All the existing `machine.UART` tests in extmod and extmod_hardware are
converted to use the new `target_wiring` scheme, which removes a lot of
duplicated board-specific settings.

All the existing boards that were supported by these UART tests now have
their own `target_wiring` file.  Some configurations are board specific (eg
NUCLEO_WB55) and others are port specific.

3285e52127 tests/run-tests.py: Add support for board-specific target_wiring config.
There are currently a few "hardware" tests that need external board
connections to be made for them to work, such as bridging a pair of pins.
For example, all tests in `tests/extmod_hardware` need some kind of
connection.

Along with the physical connections -- which are different for each board
-- there needs to be corresponding Python settings, eg which UART instance
to use and which pins for TX/RX.

These settings are currently hard-coded in each test file. That has a few
problems:
- settings are repeated, eg all the UART tests have pretty much the same
  settings code duplicated across them
- changing the settings means changing many files
- adding a new board means adding a lot of code
- the tests get bigger and bigger with each new board that they support,
  meaning they may not fit on targets with a small amount of RAM (that's
  already the case with `tests/extmod_hardware/machine_pwm.py`)
- if you have a custom board you have to manually edit the test to add your
  own settings

This commit aims to solve all the above problems by splitting the board-
specific settings out into separate files, one for each board (or port).
They are placed in the `tests/target_wiring/` directory.  The
`run-tests.py` test runner then loads the appropriate configuration for the
target that is being tested, sends it to the board so it's available as
`import target_wiring` (without needing a filesystem), and then executes
the test.  Note tht only tests that need `target_wiring` have it loaded.

This commit adds support for this `target_wiring` scheme.

b3c8ed6c33 tests/ports/rp2: Decrease test lower bound for thread lightsleep time.
This makes the rp2-specific lightsleep test more lenient, so it passes.

This test was added in PR #16454 / 69993daa5c
and even back then it did not pass reliably on RP2040.  The issue is that
threads can race each other to enter lightsleep mode, and when one of them
actually stops the CPU clock the other thread is stopped as well.
Depending on whether the other thread was just entering or just exiting
lightsleep itself, the total duration of all sleeps can vary and can be as
small as 2*T.

Therefore, adjust the minimum to allow 2*T.

`machine.lightsleep()` is anyway 1) specified only to wait at most the
given time; and 2) not well specified when multiple threads call it at the
same time.  So it seems OK to make the test more lenient.

Work done in collaboration with @projectgus.

5b98126c21 esp32/boards: Reduce flash usage of ESP32-C6 boards.
Reduces ESP32_GENERIC_C6 application flash size from 2024432 to
1813216 (206KB smaller).

Also has benefit of reducing D/IRAM size, increasing free memory at
runtime (167187 to 148584, -18603 bytes).

Most of this savings comes from building with -Os instead of -O2,
but about 10KB comes from using the SPI flash functions from the ROM.

The unix port doesn't have `micropython.alloc_emergency_exception_buf()`
but it's still possible to run and pass this test.  So make that call
optional.

f62c614d3e tests/run-multitests.py: Change -i argument to -t.
Back in commit 8978102f35 (see PR #16111) the
`run-tests.py` script was changed to use an improved way of selecting the
test instance, eg:

    $ ./run-tests.py -t a0

that would run on /dev/ttyACM0.  This has been a very nice improvement,
makes it easier to specify the target.

This commit updates `run-multitests.py` to use the same scheme.  It
previously used `-i` but now that's changed to `-t`.
