ast.parse() no longer emits syntax warnings for
return/break/continue in finally (see PEP-765) -- they are only
emitted during compilation.

gh-140082: Forward colorizing from libregrtest to unittest (GH-140083)
libregrtest redirects test output to a file as part of its operation.
When `unittest` checks to see if it should colorize with
`isatty(sys.stdout)` that fails resulting in no colorizing of the
unittest output.
Update `libregrtest` to set `FORCE_COLOR=1` when redirecting test output
so that unittest will do color printing.

While `RawIOBase.readinto` should return a count of bytes between 0 and
the length of the given buffer, it is not required to. Add validation
inside RawIOBase.read() that the returned byte count is valid.

* Count number of actually tracked objects, instead of trackable objects. This ensures that untracking tuples has the desired effect of reducing GC overhead
* Do not track most untrackable tuples during creation. This prevents large numbers of small tuples causing execessive GCs.
gh-130317: Fix SNaN broken tests on HP PA RISC (GH-140452)
While looking at GH-140028, I found some unrelated test regressions in the
3.14 cycle. These seem to all come from GH-130317. From what I can tell,
that made Python more correct than it was before. According to [0], HP PA
RISC uses 1 for SNaN and thus a 0 for QNaN.

GH-133789: Fix unpickling of pathlib objects pickled in Python 3.13 (GH-133831)
In Python 3.13 (but not 3.12 or 3.14), pathlib classes are defined in
`pathlib._local` rather than `pathlib`. In hindsight this was a mistake,
but it was difficult to predict how the abstract/local split would pan out.
In this patch we re-introduce `pathlib._local` as a stub module that
re-exports the classes from `pathlib`. This allows path objects pickled in
3.13 to be unpicked in 3.14+
