The following code:
server = await asyncio.start_server(...)
async with server:
... code that raises ...
would lose the original exception because the server's task would not have
had a chance to be scheduled yet, and so awaiting the task in wait_closed
would raise the cancellation instead of the original exception.
Additionally, ensures that explicitly cancelling the parent task delivers
the cancellation correctly (previously was masked by the server loop), now
this only happens if the server was closed, not when the task was
cancelled.

1. Remove the skip for detecting support for polling user-defined objects
as this is always possible now on all ports.
2. Don't print when the scheduled task runs as the ordering of this
relative to the other prints is dependent on other factors (e.g. if
using the native emitter).

The PYBD_SF2 is right on the limit of being able to run this test and so
it succeeds the first two cases and fails the next two with MemoryError.
This causes it to SKIP, but that only works if it's the first thing
printed. So reverse the order of the tests so it fails on the biggest
one first.

In CPython, `_thread.start_new_thread()` returns an ID that is the same ID
that is returned by `_thread.get_ident()`. The current MicroPython
implementation of `_thread.start_new_thread()` always returns `None`.
This modifies the required functions to return a value. The native thread
id is returned since this can be used for interop with other functions, for
example, `pthread_kill()` on *nix. `_thread.get_ident()` is also modified
to return the native thread id so that the values match and avoids the need
for a separate `native_id` attribute.
Fixes issue #12153.

Because mpy_ld.py doesn't know the target object representation, it emits
instances of `MP_OBJ_NEW_QSTR(MP_QSTR_Foo)` as const string objects, rather
than qstrs. However this doesn't work for map keys (e.g. for a locals dict)
because the map has all_keys_are_qstrs flag is set (and also auto-complete
requires the map keys to be qstrs).
Instead, emit them as regular qstrs, and make a functioning MP_OBJ_NEW_QSTR
function available (via `native_to_obj`, also used for e.g. making
integers).
Remove the code from mpy_ld.py to emit qstrs as constant strings, but leave
behind the scaffold to emit constant objects in case we want to do use this
in the future.
Strictly this should be a .mpy sub-version bump, even though the function
table isn't changing, it does lead to a change in behavior for a new .mpy
running against old MicroPython. `mp_native_to_obj` will incorrectly return
the qstr value directly as an `mp_obj_t`, leading to unexpected results.
But given that it's broken at the moment, it seems unlikely that anyone is
relying on this, so it's not work the other downsides of a sub-version bump
(i.e. breaking pure-Python modules that use @native). The opposite case of
running an old .mpy on new MicroPython is unchanged, and remains broken in
exactly the same way.

This adds support for the x format code in struct.pack and struct.unpack.
The primary use case for this is ignoring bytes while unpacking. When
interfacing with existing systems, it may often happen that you either have
fields in a struct that aren't properly specified or you simply don't care
about them. Being able to easily skip them is useful.

The only reason that const had to be disabled was to make the test output
match CPython when const was involved. Instead, this commit fixes the test
to handle the lines where const is used.
Also:
- remove the special handling for MICROPY_PERSISTENT_CODE_SAVE in
unix/mpconfigport.h, and make this automatic.
- move the check for MICROPY_PERSISTENT_CODE_SAVE to where it's used (like
we do for other similar checks) and add a comment explaining it.

This test was failing on CPython 3.11 as it now emits `0` as the line
number for the "call" event corresponding to import, where as in 3.6 it had
`1` as the line number.
We maintain the old behavior, but in order to make this test pass on both
CPython versions, the trace handler now converts the `0` to a `1`.

An SSL stream can only handle CLOSE and POLL ioctls. Other ones do not
make sense, or at least it doesn't make sense to pass the ioctl request
directly down to the underlying stream.
In particular MP_STREAM_GET_FILENO should not be passed to the underlying
stream because the SSL stream is not directly related to a file descriptor,
and the SSL stream must handle the polling itself.

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

gzip.GzipFile.

Prior to this fix, async for assumed the iterator expression was a simple
identifier, and used that identifier as a local to store the intermediate
iterator object. This is incorrect behaviour.

This commit adds the SSLContext class to the ssl module, and retains the
existing ssl.wrap_socket() function to maintain backwards compatibility.
CPython deprecated the ssl.wrap_socket() function since CPython 3.7 and
instead one should use ssl.SSLContext().wrap_socket(). This commit makes
that possible.
For the axtls implementation:
- ssl.SSLContext is added, although it doesn't hold much state because
axtls requires calling ssl_ctx_new() for each new socket
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added
For the mbedtls implementation:
- ssl.SSLContext is added, and holds most of the mbedtls state
- ssl.verify_mode is added (getter and setter)
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added
The signatures match CPython:
- SSLContext(protocol)
- SSLContext.wrap_socket(sock, *, server_side=False,
do_handshake_on_connect=True, server_hostname=None)
The existing ssl.wrap_socket() functions retain their existing signature.

PEP-498 allows for conversion specifiers like !r and !s to convert the
expression declared in braces to be passed through repr() and str()
respectively.
This updates the logic that detects the end of the expression to also stop
when it sees "![rs]" that is either at the end of the f-string or before
the ":" indicating the start of the format specifier. The "![rs]" is now
retained in the format string, whereas previously it stayed on the end
of the expression leading to a syntax error.
Previously: `f"{x!y:z}"` --> `"{:z}".format(x!y)`
Now: `f"{x!y:z}"` --> `"{!y:z}".format(x)`
Note that "!a" is not supported by `str.format` as MicroPython has no
`ascii()`, but now this will raise the correct error.
Updated cpydiff and added tests.

Prior to this commit, importing a module that exists but has a syntax error
or some other problem that happens at import time would result in a
potentially-incomplete module object getting added to sys.modules.
Subsequent imports would use that object, resulting in confusing error
messages that hide the root cause of the problem.
This commit fixes that issue by removing the failed module from sys.modules
using the new NLR callback mechanism.
Note that it is still important to add the module to sys.modules while the
import is happening so that we can support circular imports just like
CPython does.
Fixes issue #967.
