GH-130614: pathlib ABCs: improve support for receiving path metadata (#131259) 
In the private pathlib ABCs, replace `_WritablePath._write_info()` with
`_WritablePath._copy_from()`. This provides the target path object with
more control over the copying process, including support for querying and
setting metadata *before* the path is created.

Adjust `_ReadablePath.copy()` so that it forwards its keyword arguments to
`_WritablePath._copy_from()` of the target path object. This allows us to
remove the unimplemented *preserve_metadata* argument in the ABC method,
making it a `Path` exclusive.

GH-130614: pathlib ABCs: delete vestigial test_pathlib_abc module (#131215) 
Remove the `test.test_pathlib.test_pathlib_abc` test module, which was
hollowed out in previous commits. Its few remaining tests are most relevant
to `PurePath` and `Path`, so we move them into `test_pathlib`.

gh-129149: Add fast path for medium-sized integers in PyLong_FromSsize_t() (#129301) 
The implementation of `PyLong_FromLong()`, `PyLong_FromLongLong()` and `PyLong_FromSsize_t()`
are now handled by a common macro `PYLONG_FROM_INT` which contains fast paths depending on the
size of the integer to convert. Consequently, `PyLong_FromSsize_t()` for medium-sized integers is faster
by roughly 25%.

gh-130806: Emit ResourceWarning if GzipFile unclosed (#130905) 
This may indicate accidental data loss.

Ways to make sure all data is written:
1. Use the [file-like object](https://docs.python.org/3/glossary.html#term-file-object) as a [“With Statement Context Manager”](https://docs.python.org/3/reference/datamodel.html#context-managers).
   - All objects which [inherit](https://docs.python.org/3/tutorial/classes.html#inheritance) from [IOBase](https://docs.python.org/3/library/io.html#io.IOBase) support this.
   - [`BufferedIOBase`](https://docs.python.org/3/library/io.html#io.BufferedIOBase), [`BufferedWriter`](https://docs.python.org/3/library/io.html#io.BufferedWriter), and [`GzipFile`](https://docs.python.org/3/library/gzip.html#gzip.GzipFile) all support this.
   - Ensures `.close()` is called in both exception and regular cases.

2. Ensure [`.close()`](https://docs.python.org/3/library/io.html#io.IOBase.close) is always called which flushes data before closing.

3. If the underlying stream need to be kept open, use [`.detach()`](https://docs.python.org/3/library/io.html#io.BufferedIOBase.detach)

Since 3.12 flushing has been necessary in GzipFile (see gh-105808 which was a release blocker), this makes that more visible. Users have been encountering as they upgrade to 3.12 (ex. gh-129726).

There are a number of cases of unclosed file-like objects being deleted in CPython libraries and the test suite. This issue includes resolving those cases where the new ResourceWarning is emitted.

gh-127503: Improve tracebacks on Emscripten when there is a trap (#131158) 
Modifies the behavior of the interpreter on crash under Emscripten:
1. No Python traceback shown on segfault/trap
2. The JavaScript source line is shown

The JavaScript source line is super long and completely unenlightening,
whereas the Python traceback is very helpful.

gh-115999: Add free-threaded specialization for FOR_ITER (#128798) 
Add free-threaded versions of existing specialization for FOR_ITER (list, tuples, fast range iterators and generators), without significantly affecting their thread-safety. (Iterating over shared lists/tuples/ranges should be fine like before. Reusing iterators between threads is not fine, like before. Sharing generators between threads is a recipe for significant crashes, like before.)
