Commit dc2fcfcc5511a371ff684f7d7772e7a7b479246d seems to have accidentally
changed the ruff quote style to "preserve", instead of keeping it at the
default which is "double".
Put it back to the default and update relevant .py files with this rule.

- DTLS spec recommends HelloVerify and Anti Replay protection be enabled,
and these are enabled in the default mbedTLS config. Implement them here.
- To help compensate for the possible increase in code size, add a
MICROPY_PY_SSL_DTLS build config macro that's enabled for EXTRA and
above by default.
This allows bare metal mbedTLS ports to use DTLS with HelloVerify support.

This is a workaround for the case where threading is enabled without a GIL.
In such a configuration, creating a new global variable is not atomic and
threads have race conditions resizing/accessing the global dict.

These tests cover the use of mp_obj_new_int_from_str_len when
mp_parse_num_integer overflows the SMALLINT limit, and also the case where
the value may not be null terminated.
Placed in a separate test file so that extmod/json test doesn't rely on
bigint support.

These will run on all ports which support them, but importantly
they'll also run on ports that don't support arbitrary precision
but do support 64-bit long ints.
Includes some test workarounds to account for things which will overflow
once "long long" big integers overflow (added in follow-up commit):
- uctypes_array_load_store test was failing already, now won't parse.
- all the ffi_int tests contain 64-bit unsigned values, that won't parse
as long long.

This is code makes sure that time functions work properly on a
reasonable date range, on all platforms, regardless of the epoch.
The suggested minimum range is 1970 to 2099.
In order to reduce code footprint, code to support far away dates
is only enabled specified by the port.
New types are defined to identify timestamps.
The implementation with the smallest code footprint is when
support timerange is limited to 1970-2099 and Epoch is 1970.
This makes it possible to use 32 bit unsigned integers for
all timestamps.
On ARM4F, adding support for dates up to year 3000 adds
460 bytes of code. Supporting dates back to 1600 adds
another 44 bytes of code.

This test was factored out from `random_extra.py` back in commit
6572029dc0665e58c2ea7355c9e541bdf83105a4, and the skip logic copied from
that file. But the skip logic needs to test that the `random` and
`uniform` functions exist, not `randint`.
This commit fixes that skip logic.

Currently the `FrameBuffer.blit(buf, x, y)` method requires the `buf`
argument to be another `FrameBuffer`, which is quite restrictive because it
doesn't allow blit'ing read-only memory/data.
This commit extends `blit()` to allow the `buf` argument to be a tuple or
list of the form:
(buffer, width, height, format[, stride])
where `buffer` can be anything with the buffer protocol and may be
read-only, eg `bytes`.
Also, the palette argument to `blit()` may be of the same form.
The form of this tuple/list was chosen to be the same as the signature of
the `FrameBuffer` constructor (that saves quite a bit of code size doing it
that way).

This commit makes the JSON parser raise an exception when handling
objects or arrays whose declaration is incomplete, as in missing the
closing marker (brace or bracket) and if the missing marker would have
been the last non-whitespace character in the incoming string.
Since CPython's JSON parser would raise an exception in such a case,
unlike MicroPython's, this commit aligns MicroPython's behaviour with
CPython.
This commit fixes issue #17141.

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.

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.

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 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).

Test is for an issue reported on the micropython-lib Discord as
effecting the rp2 port umqtt.simple interface when reconnecting with TLS,
however it's a more generic problem.

others). Fixes are in the subsequent commits.

This commit fixes a test failure for `extmod/re_sub.py` where the code,
whilst being correct, would not make the test pass due to a newer
Python version than expected.
On Python 3.13, running `tests/extmod/re_sub.py` would yield a
deprecation warning about `re.sub` not providing the match count as a
keyword parameter. This warning would be embedded in the expected test
result and thus the test would always fail.

This started failing in CI on the mingw build, after CPython updated to
3.12.7. The test prints two warnings during interpreter shutdown of
"Task was destroyed but it is pending!".
This didn't happen on other CPython builds, and I think that's because of
finalizer order in CPython interpreter shutdown but not certain (the loop
finalizer calls loop.close() if not already closed).
Adding explicit calls to loop.close() causes the warning to be printed on
every run with CPython 3.12.7 on Linux.
Next, added the workaround exception handler to swallow this exception
as MicroPython doesn't produce an equivalent.

This fixes a bug in FrameBuffer.ellipse where it goes into an infinite loop
if both radii are 0.
This fixes the bug with a simple pre-check to see if both radii are 0, and
in that case sets a single pixel at the center. This is consistent with the
behaviour of the method when called with just one of the radii set to 0,
where it will draw a horizontal or vertical line of 1 pixel width.
The pixel is set with setpixel_checked so it should handle out-of-bounds
drawing correctly.
This fix also includes three new tests: one for the default behaviour, one
for drawing out-of-bounds, and one for when the sector mask is 0.
Fixes issue #16053.

Getting this test running on stm32- and mimxrt-based boards requires adding
a small delay after constructing the UART so that the initial idle frame
has time to be transmitted before the test starts.
Also, the timing margin needs to account for an additional 1-bit worth of
time on some MCUs.

Some ports (eg stm32) configure the FAT driver differently (eg with
multi-partition support) and that leads to a slightly different sequence of
block reads, compared to other configurations (eg rp2).
Comment out the printing in `readblocks()` so the tests are deterministic
(the printing is still useful for debugging).
