This groups non-decimal values by fours, such as bbb_bbbb_bbbb. It also
supports `{:_d}` to use underscore for decimal numbers (grouped in threes).
Use of incorrect ":,b" is not diagnosed.
Thanks to @dpgeorge for the suggestion to reduce code size.

There's no specified behaviour for what should happen if both CPUs call
`lightsleep()` together, but the latest changes could cause a permanent
hang due to a race in the timer cleanup code. Add a flag to prevent hangs
if two threads accidentally lightsleep, at least.
This allows the new lightsleep test to pass on RPI_PICO and RPI_PICO2, and
even have much tighter time deltas. However, the test still fails on
wireless boards where the lwIP tick wakes them up too frequently.

The Let's Encrypt root certificate has changed so needs updating in these
tests.
Also use `bytes.fromhex()` instead of `binascii.unhexlify()`, to eliminate
the need for the `binascii` module. Both of these features are controlled
by `MICROPY_PY_BUILTINS_BYTES_HEX`, so the test will still work on the same
targets that it previously did.

This commit fixes three open issues related to the asyncio scheduler
exiting prematurely when the main task queue is empty, in cases where
CPython would not exit (for example, because the main task is not done
because it's on a different queue).
In the first case, the scheduler exits because running a task via
`run_until_complete` did not schedule any dependent tasks.
In the other two cases, the scheduler exits because the tasks are queued in
an event queue.
Tests have been added which reproduce the original issues. These test
cases document the unauthorized use of `Event.set()` from a soft IRQ, and
are skipped in unsupported environments (webassembly and native emitter).
Fixes issues #16759, #16569 and #16318.

Fixes thread safety issue that could cause memory corruption on ports
with (MICROPY_PY_THREAD && !MICROPY_PY_THREAD_GIL) - currently only rp2 and
unix have this configuration.
Adds unit test for TLS sockets that exercises this code path. I wasn't
able to make this fail on rp2, the race condition window is pretty narrow
and may not have a direct impact on a quiet system.

Changes in this commit:
- Allow the DMA instance to be any instance, not just DMA(0); eg WLAN may
be using DMA(0).
- Make the DMA timing test run a little faster by preloading `dma.active`.
- Run the DMA timing test 10 times and take the average time taken as the
test result, to eliminate any big effects of caching.
- Change the expected time to `range(30, 80)` to cover RP2040, RP2350,
RISC-V variants, and both bytecode and native emitter.
- Add a `sleep_ms(1)` after waiting for the IRQ to fire, so that any
scheduled code gets a chance to run when the test is compiled with the
native emitter.
With these changes this test passes reliably on RPI_PICO, RPI_PICO_W,
RPI_PICO2, RPI_PICO2_W, RPI_PICO2-RISCV and RPI_PICO2_W-RISCV, in both
bytecode and native emitter mode, with and without WLAN enabled.

Only a few ports have TCP/IP loopback enabled in their network stack, and
this test will only pass on those ports. There's not really any good way
to do a feature check for loopback mode without actually running the test
and seeing if it passes/fails, so add an explicit check that the test is
running on a port known to support loopback.
(Enabling loopback on lwIP, eg RPI_PICO_W, costs +568 code and +272 bss and
is a rarely used feature, so not worth unconditionally enabling.)

This commit makes a slight change to the vfs_posix test suite to let it
pass on Android.
On Android, non-root processes can perform most filesystem operations
only on a restricted set of directories. The vfs_posix test suite
attempted to enumerate the filesystem root directory, and said directory
happens to be restricted for non-root processes. This would raise
an EACCES OSError and terminate the test with a unexpected failure.
To fix this, rather than enumerating the filesystem root directory the
enumeration target is the internal shared storage area root - which
doesn't have enumeration restrictions for non-root processes. The path
is hardcoded because it is guaranteed to be there on pretty much any
recent-ish device for now (it stayed the same for more than a decade for
compatibility reasons). The proper way would be to query the storage
subsystem via a JNI round-trip call, but this introduces too much
complexity for something that is unlikely to break going forward.

Allocation of a large compression window may fail, and in that case keep
the `DeflateIO` state consistent so its other methods (such as `close()`)
still work. Consistency is kept by only updating the `self->write` member
if the window allocation succeeds.

For a given MicroPython firmware/executable it can be sometimes important
to know how it was built, which variant/board configuration it came from.
This commit adds a new field `sys.implementation._build` that can help
identify the configuration that MicroPython was built with.
For now it's either:
* <VARIANT> for unix, webassembly and windows ports
* <BOARD>-<VARIANT> for microcontroller ports (the variant is optional)
In the future additional elements may be added to this string, separated by
a hyphen.
Resolves issue #16498.

This change allows tuples to be passed as the prefix/suffix argument to the
`str.startswith()` and `str.endswith()` methods. The methods will return
`True` if the string starts/ends with any of the prefixes/suffixes in the
tuple.
Also adds full support for the `start` and `end` arguments to both methods
for compatibility with CPython.
Tests have been updated for the new behaviour.

The mantissa parsing code uses a floating point variable to accumulate
digits. Using an `mp_float_uint_t` variable instead and casting to
`mp_float_t` at the very end reduces code size. In some cases, it also
improves the rounding behaviour as extra digits are taken into account
by the int-to-float conversion code.
An extra test case handles the special case where mantissa overflow occurs
while processing deferred trailing zeros.

Testing with ROMFS shows that it is relatively easy to end up with a
corrupt filesystem on the device -- eg due to the ROMFS deploy process
stopping half way through -- which could lead to hard crashes. Notably,
there can be boot loops trying to mount a corrupt filesystem, crashes when
importing modules like `os` that first scan the filesystem for `os.py`, and
crashing when deploying a new ROMFS in certain cases because the old one is
removed while still mounted.
The main problem is that `mp_decode_uint()` has an loop that keeps going as
long as it reads 0xff byte values, which can happen in the case of erased
and unwritten flash.
This commit adds full bounds checking in the new `mp_decode_uint_checked()`
function, and that makes all ROMFS filesystem accesses robust.

This adds a multi-test for DTLS server and client behaviour. It works on
all ports that enable this feature (eg unix, esp32, rp2, stm32), but
bare-metal ports that use lwIP are not reliable as the DTLS server because
the lwIP bindings only support queuing one UDP packet at a time (that needs
to be fixed).
Also, to properly implement a DTLS server sockets need to support
`socket.recvfrom(n, MSG_PEEK)`. That can be implemented in the future.

This commit enables support for DTLS, i.e. TLS over datagram transport
protocols like UDP. While support for DTLS is absent in CPython, it is
worth supporting it in MicroPython because it is the basis of the
ubiquitous CoAP protocol, used in many IoT projects.
To select DTLS, a new set of "protocols" are added to SSLContext:
- ssl.PROTOCOL_DTLS_CLIENT
- ssl.PROTOCOL_DTLS_SERVER
If one of these is set, the library assumes that the underlying socket is a
datagram-like socket (i.e. UDP or similar).
Our own timer callbacks are implemented because the out of the box
implementation relies on `gettimeofday()`.
This new DTLS feature is enabled on all ports that use mbedTLS.
This commit is an update to a previous PR #10062.
Addresses issue #5270 which requested DTLS support.

It's not necessary to support this, which allows an arbitrary memory
address to be specified and potentially allows invalid memory accesses.
Requiring an object with the buffer protocol is safer, and also means that
the length of the region is always specified.

This commit implements a small subset of the CPython `marshal` module. It
implements `marshal.dumps()` and `marshal.loads()`, but only supports
(un)marshalling code objects at this stage. The semantics match CPython,
except that the actual marshalled bytes is not compatible with CPython's
marshalled bytes.
The module is enabled at the everything level (only on the unix coverage
build at this stage).

This commit lets the natmod tests runner to automatically detect the
architecture of the test target. This allows to avoid to explicitly
pass the architecture name to the runner in test scripts.
However, the ability to manually specify a target was not removed but it
was made optional. This way the user is able to override the
architecture name if needed (like if one wants to test an armv6 MPY on
an armv7 board).
