The linked list of objects was a global variable, which broke isolation between interpreters, causing crashes. To solve this, we've moved the linked list to each interpreter.
Introduce ClinicError, and use it in fail(). The CLI runs main(),
catches ClinicError, formats the error message, prints to stderr
and exits with an error.
As a side effect, this refactor greatly improves the accuracy of
reported line numbers in case of error.
Also, adapt the test suite to work with ClinicError.

gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module.
The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests.
(This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)
The motivation for this change is to clean up the output_templates()
method a little bit, as it accounts for ~10% of the lines of code in
clinic.py; removing some clutter helps readability.
Previously, only function docstrings were checked for non-ASCII characters.
Also, improve the warn() message.

Introduce docstring_append() helper, and use it for both parameter and
function docstrings. Remove docstring fixup from
do_post_block_processing_cleanup(); instead, make sure no fixup is needed.

- Use ArgumentParser.error() to handle CLI errors
- Put the entire CLI in main()
- Rework ClinicExternalTest to call main() instead of using subprocesses

It was possible for the trashcan to delay the deallocation of a
PyFrameObject until after its corresponding _PyInterpreterFrame has
already been freed. So frame_dealloc needs to avoid dereferencing the
f_frame pointer unless it first checks that the pointer still points
to the interpreter frame within the frame object.

There's no need to use a dummy uop to skip unused cache entries. The macro syntax lets you write `unused/1` instead.
Similarly, move `unused/5` from op `_LOAD_ATTR_INSTANCE_VALUE` to macro `LOAD_ATTR_INSTANCE_VALUE`.
Represent IPv4-mapped IPv6 address as x❌x❌x❌d.d.d.d,
where the 'x's are the hexadecimal values
of the six high-order 16-bit pieces of the address,
and the 'd's are the decimal values
of the four low-order 8-bit pieces of the address
(standard IPv4 representation).
