datetime.isoformat generates the tzoffset with colons, but there
was no format code to make strftime output the same format.
for simplicity and consistency the %:z formatting behaves mostly
as %z, with the exception of adding colons. this includes the
dynamic behaviour of adding seconds and microseconds only when
needed (when not 0).
this fixes the still open "generate" part of this issue:

* inspect.getsource: avoid stat on file in linecache
The check for os.path.exists() on source file is postponed in
inspect.getsourcefile() until needed avoiding an expensive filesystem
stat call and PEP 302 module loader check is moved last for performance
since it is an uncommon case.
Editors don't agree that `test_source_encoding.py` was valid koi8-r, making it
hard to edit that file without the editor breaking it in some way (see gh-96272).
Only one test actually relied on the koi8-r encoding and it was a duplicate of a
test from the deprecated `imp` module's `test_imp`, so here we replace
`test_pep263` with `test_import_encoded_module` stolen from `test_imp` and
set `test_source_encoding.py`'s encoding to utf-8 to make editing it easier
going forward.
find_unused_port() has an inherent race condition, but we can't use
bind_port() as that uses .getsockname() which this test is exercising.
Try binding to unused ports a few times before failing.

Tests for IsolatedAsyncioTestCase.debug() rely on the runner be closed
in __del__. It makes tests depending on the GC an unreliable on other
implementations. It is better to close the runner explicitly even if
currently there is no a public API for this.
The clearing of the temporary directory is not working on some platforms and
leaving behind files.
This has been updated to use the pattern in test_cmd_line.py [1] using the
special TESTFN rather than a test directory.

* Treat tp_weakref and tp_dictoffset like other opaque slots for multiple inheritance.
* Document Py_TPFLAGS_MANAGED_DICT and Py_TPFLAGS_MANAGED_WEAKREF in what's new.
- Limited API needs to be enabled per source file
- Some builds don't support Limited API, so Limited API tests must be skipped on those builds
(currently this is `Py_TRACE_REFS`, but that may change.)
- `Py_LIMITED_API` must be defined before `<Python.h>` is included.
This puts the hoop-jumping in `testcapi/parts.h`, so individual
test files can be relatively simple. (Currently that's only
`vectorcall_limited.c`, imagine more.)
When a task catches CancelledError and raises some other error,
the other error should not silently be suppressed.
Any scenario where a task crashes in cleanup upon cancellation
will now result in an ExceptionGroup wrapping the crash(es)
instead of propagating CancelledError and ignoring the side errors.
NOTE: This represents a change in behavior (hence the need to
change several tests). But it is only an edge case.

When loading a source file from disk, there is a separate UTF-8 validator
distinct from the one in `unicode_decode_utf8`. This exercises that code path
with the same set of invalid inputs as we use for testing the "other" UTF-8
decoder.
