gh-150046: Fix `test_add_python_opts` to ignore `PYTHON*` env vars (GH-150089)

which notably checks the warning filters which can be controlled by
various PYTHON environment variables.

gh-150175: Fix ThreadingMock call_count race condition (GH-150176)
ThreadingMock._increment_mock_call() was not thread-safe.
Multiple threads calling the mock simultaneously could lose
increments due to race conditions on call_count and other
attributes.
Fix by overriding _increment_mock_call in ThreadingMixin
and wrapping it with the existing _mock_calls_events_lock.

gh-150258: Show relative percentage on Tachyon flamegraph (GH-150266)
When running profiling, users rarely care about the global percentage of
the runtime. Often, they want to select a function and measure child
percentages relative to that.
This PR updates the flamegraph tooltips to show both "Percentage" and
"Relative Percentage" when the user clicks a specific function.

gh-149995: Update typing.py docstrings and documentation (GH-149996)
Some of these docstrings read as if they were written when typing.py was
first written, and things have evolved since then.
A few motivations:
- Call protocols protocols instead of ABCs. They are also ABCs, but the fact
they are protocols is more relevant to typing.
- Avoid recommending direct use of .__annotations__ and steer users to
annotationlib instead.
- For TypedDict, mention NotRequired before total=False since it is more
general and probably more frequently useful.
- For overloads, mention runtime use first instead of stub use. I think early on
there was talk of allowing overload only in stubs, but it is now heavily used at
runtime too and that's more likely to be relevant to users.

gh-149819: fix .pth and .start file processing in subprocess when inheriting PYTHONPATH (GH-150177)
* gh-149819: Fix .pth files not loaded in Python subprocesses
After PR gh-149583 (Fix double evaluation of .pth and .site files in
venvs), .pth files are no longer loaded in subprocesses started with
subprocess.run([sys.executable, ...]). The root cause: main() seeds
known_paths from removeduppaths() with all sys.path entries inherited
from the parent process. addsitedir() then skips .pth processing for
every directory already in known_paths.
Fix:
- main(): call removeduppaths() for dedup but start known_paths as a
fresh empty set, so that addsitedir() processes .pth files in every
site-packages directory regardless of inherited sys.path.
- addsitedir(): move known_paths.add() before the sys.path.append and
guard the append with 'sitedir not in sys.path' to avoid creating
duplicate entries when called with a fresh known_paths.
This preserves the gh-75723 dedup guarantee while allowing subprocesses
to load .pth files.
* Fill out the tests for GH#149888
* Extend _make_start() and _make_pth() to take an optional `basedir` which is used instead of
`site.tmpdir` if given.
* Add test_pth_processed_when_sitedir_already_on_path() to test the core GH#149819 bug: .pth files
in subprocesses aren't handled if PYTHONPATH pointing to the .pth directory is inherited.
* Similarly add test_start_processed_when_sitedir_already_on_path() to verify that .start files in
the same circumstances are also now processed.
* Update Lib/site.py
* Oops! Remove redundant code

bpo-42367: Restore os.makedirs() and pathlib.mkdir() ability to apply *mode* recursively via a new parent_mode= keyword argument.
(cherry picked from commit 9770e32ce0)
+ Make Path.mkdir parent_mode tests umask-independent
test_mkdir_with_parent_mode, test_mkdir_parent_mode_deep_hierarchy and
test_mkdir_parent_mode_same_as_mode assert exact directory mode bits but
did not pin the process umask. On buildbots running with a restrictive
umask (e.g. 0o077) the 0o755 leaf was masked down to 0o700, failing the
assertions. Wrap them in os_helper.temp_umask(0o022), matching the
other umask-aware mkdir tests in this file.
