Zephyr v3.2.0 deprecated the devicetree label property as a base

device_get_binding(). The device name string is now the devicetree node
name appended with its unit-address. Update Zephyr port documentation
to reflect this change.

The ESP32 port contains a workaround to avoid having a certain function
in `py/parse.c` being generated incorrectly. The compiler in question
is not part of any currently supported version of ESP-IDF anymore, and the
problem inside the compiler (well, assembler in this case) has been
corrected a few years ago.
This commit removes all traces of that workaround from the source tree.

Necessary to fix "mpremote run" over hardware UART.
Bisect shows bug was introduced by d420b4e4, but looks like made more
complex by 01c046d2. Specifically: resetting and re-initialising the REPL
UART during soft reset clears the FIFO before it's done printing the "MPY:
soft reboot" line.
Fixed by adding a UART TX flush in the deinit path.

lwIP was recently updated in a89ac9e24a
to STABLE-2_2_0_RELEASE, and this introduced a change in the configuration
variable `DHCP_DOES_ARP_CHECK`, renaming it to `LWIP_DHCP_DOES_ACD_CHECK`.
This commit fixes the ports lwIP settings to use the new configuration
option.
Without this option, connecting to a WiFi access-point takes about 12.5
seconds. With this option (ie disabling DHCP ARP checks) connecting takes
about 4 seconds.
Tested on an RPI_PICO_W and PYBD_SF2.

This tracing was originally needed for three reasons:
1. To trace object/raw-code pointers embedded in native code, eg from
@micropython.native functions.
2. To trace pointers to BSS/rodata from relocated viper code.
3. For libffi tracing.
The tracing in point 1 was made unnecessary long ago in commit
7d4b6cc868 (see also commit
bbccb0f630 which removed scanning of native
code on the esp8266 port).
Since the previous commit, point 2 is no longer needed.
For point 3, this was made unnecessary in the recent commit
9796625457.

- Code size saving as all of these functions are very similar.
- Resolves the "TODO" of the plain read and write functions not propagating
errors. An error in the underlying block device now causes VFatFs to
return EIO, for example.

A positive result here can result in eventual memory corruption
as littlefs expects the result of a cache read/write function to be

The UART driver enables a pull-up on RX/CTS pins by default. This can

When testing the Unix port with FFI tests enabled, the FFI helper
library that's built as part of the testing process is not removed after
the tests session end.

in the past.

This commit clears the upper 32 bits of returned `uint32_t` values,
which are handled as `unsigned int`s by the MicroPython runtime and
thus could be extended to 64 bits on some platforms.
RV64 holds 32-bit values as signed integers when held in registers, but
the code handling the FFI unsigned int case did not take this into
account. That introduced test failures when a 32-bit value had its most
significant bit set, as when performing the value extension from 32 to
64 bits, the upper half of the value would be filled with ones.
On 32 bit platforms this change should be converted to a no-op, and
on other 64 bit platforms that aren't RISC-V it shouldn't hurt as the
value being manipulated is expected to only hold valid bits in its lower
half.

This commit removes custom FFI closures alloc/free functions, in favour
of using the tracked allocation facility to allocate memory for FFI
callback objects.
This stems from linking issues in the Arm port when updating LibFFI to
the latest stable version, as the overridden alloc/free functions didn't
replace LibFFI's (unlike in other ports). The original code did no
effective cleanup for allocated callback objects, so there is no real
impact when switching allocation strategy.
The tracked allocation feature used to be enabled only if the Bluetooth
stack integration was enabled. This commit also enables tracked
allocation support if FFI support is enabled.

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.

This commit adds a new `RingIO` type which exposes the internal ring-buffer
code for general use in Python programs. It has the stream interface
making it similar to `StringIO` and `BytesIO`, except `RingIO` has a fixed
buffer size and is automatically safe when reads and writes are in
different threads or an IRQ.
This new type is enabled at the "extra features" ROM level.

Added the "long" modffi tests. The tests could not be added to the existing
ffi_types test because two .exp files were required for the 32-bit and
64-bit results. Code common to both the ffi_types and type "long" tests was
factored into ffi_int_base. ffi_types was renamed to ffi_int_types to group
the related tests under the "ffi_int" prefix.

Casting an ffi_arg to a signed int may truncate the value. E.g., when the
ffi_arg is 64-bit and the signed int is 32-bit. Also, casting an ffi_arg
to a larger signed type will not sign extend the value. E.g., when the
ffi_arg is 32-bit and the larger signed type is int64_t. If the value is
signed, it should be cast to ffi_sarg, which is the same size as ffi_arg.

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.

If GIL is disabled then there's threat of a race condition if some other
code specifically requests USB processing (i.e. to unblock stdio), while
a scheduled TinyUSB callback is already running on another thread.
Relies on the change in the parent commit, where scheduler is restricted
to main thread if GIL is disabled.
Fixes#15390 - "TinyUSB callback can't recurse" exceptions on rp2 when
using _thread module and USB serial I/O.
Adds a unit test for stdin functioning correctly in threads (fails on rp2
port without this fix).
