gh-106320: Move private _PyHash API to the internal C API (#107026)
* No longer export most private _PyHash symbols, only export the ones
which are needed by shared extensions.
* Modules/_xxtestfuzz/fuzzer.c now uses the internal C API.
gh-69714: Make `calendar` module fully tested (#93655)
There are 3 paths to use `locale` argument in
`calendar.Locale{Text|HTML}Calendar.__init__(..., locale=None)`:
(1) `locale=None` -- denotes the "default locale"[1]
(2) `locale=""` -- denotes the native environment
(3) `locale=other_valid_locale` -- denotes a custom locale
So far case (2) is covered and case (1) is in 78935daf5a (same branch).
This commit adds a remaining case (3).
[1] In the current implementation, this translates into the following
approach:
GET current locale
IF current locale == "C" THEN
SET current locale TO ""
GET current locale
ENDIF
* Remove unreachable code (and increase test coverage)
This condition cannot be true. `_locale.setlocale()` from the C module
raises `locale.Error` instead of returning `None` for
`different_locale.__enter__` (where `self.oldlocale` is set).
* Expand the try clause to calls to `LocaleTextCalendar.formatmonthname()`.
This method temporarily changes the current locale to the given locale,
so `_locale.setlocale()` may raise `local.Error`.

gh-106320: Remove private _PyUnicode_AsString() alias (#107021)
Remove private _PyUnicode_AsString() alias to PyUnicode_AsUTF8(). It
was kept for backward compatibility with Python 3.0 - 3.2.
The PyUnicode_AsUTF8() is available since Python
3.3. The PyUnicode_AsUTF8String() function can be used to keep
compatibility with Python 3.2 and older.
Add test for the 'destination <name> clear' command,
and the 'destination' directive in general.
Fix two bugs in 'destination <name> clear' command:
1. The text attribute of the allocator is called 'text', not '_text'
2. Return after processing the 'clear' command,
instead of proceeding directly to the fail().

gh-105699: Fix a Crasher Related to a Deprecated Global Variable (gh-106923)
There was a slight race in _Py_ClearFileSystemEncoding() (when called from _Py_SetFileSystemEncoding()), between freeing the value and setting the variable to NULL, which occasionally caused crashes when multiple isolated interpreters were used. (Notably, I saw at least 10 different, seemingly unrelated spooky-action-at-a-distance, ways this crashed. Yay, free threading!) We avoid the problem by only setting the global variables with the main interpreter (i.e. runtime init).

gh-105699: Fix an Interned Strings Crasher (gh-106930)
A static (process-global) str object must only have its "interned" state cleared when no longer interned in any interpreters. They are the only ones that can be shared by interpreters so we don't have to worry about any other str objects.
We trigger clearing the state with the main interpreter, since no other interpreters may exist at that point and _PyUnicode_ClearInterned() is only called during interpreter finalization.
We do not address here the fact that a string will only be interned in the first interpreter that interns it. In any subsequent interpreters str.state.interned is already set so _PyUnicode_InternInPlace() will skip it. That needs to be addressed separately from fixing the crasher.
gh-105540: Show source files relative to root (#106927)

threadingmock: Improve test suite to avoid race conditions
Simplify tests and split them into multiple tests to prevent assertions
from triggering race conditions.
Additionally, we rely on calling the mocks without delay to validate the
functionality of matching calls.
gh-106581: Add 10 new opcodes by allowing `assert(kwnames == NULL)` (#106707)
By turning `assert(kwnames == NULL)` into a macro that is not in the "forbidden" list, many instructions that formerly were skipped because they contained such an assert (but no other mention of `kwnames`) are now supported in Tier 2. This covers 10 instructions in total (all specializations of `CALL` that invoke some C code):
- `CALL_NO_KW_TYPE_1`
- `CALL_NO_KW_STR_1`
- `CALL_NO_KW_TUPLE_1`
- `CALL_NO_KW_BUILTIN_O`
- `CALL_NO_KW_BUILTIN_FAST`
- `CALL_NO_KW_LEN`
- `CALL_NO_KW_ISINSTANCE`
- `CALL_NO_KW_METHOD_DESCRIPTOR_O`
- `CALL_NO_KW_METHOD_DESCRIPTOR_NOARGS`
- `CALL_NO_KW_METHOD_DESCRIPTOR_FAST`
gh-106529: Generate uops for POP_JUMP_IF_[NOT_]NONE (#106796)
These aren't automatically translated because (ironically)
they are macros deferring to POP_JUMP_IF_{TRUE,FALSE},
which are not viable uops (being manually translated).
The hack is that we emit IS_NONE and then set opcode and
jump to the POP_JUMP_IF_{TRUE,FALSE} translation code.
