gh-119118: Fix performance regression in tokenize module (#119615) 
* gh-119118: Fix performance regression in tokenize module

- Cache line object to avoid creating a Unicode object
  for all of the tokens in the same line.
- Speed up byte offset to column offset conversion by using the
  smallest buffer possible to measure the difference.

gh-117865: Defer import of re in ast (#119546) 
This is used only by ast.get_source_segment(), so it seems sensible to avoid importing it.

gh-117398: gh-119655: datetime: Init static state once & don't free it (GH-119662) 
- While datetime uses global state, only initialize it once.
- While `capi` is static, don't free it (thanks @neonene in https://github.com/python/cpython/pull/119641/files#r1616710048)

gh-119584: Fix test_import Failed Assertion (gh-119623) 
The fix in gh-119561 introduced an assertion that doesn't hold true if any of the three new test extension modules are loaded more than once.  This is fine normally but breaks if the new test_check_state_first() is run more than once, which happens for refleak checking and with the regrtest --forever flag.  We fix that here by clearing each of the three modules after loading them.  We also tweak a check in _modules_by_index_check().

GH-82805: Fix handling of single-dot file extensions in pathlib (#118952) 
pathlib now treats "`.`" as a valid file extension (suffix). This brings
it in line with `os.path.splitext()`.

In the (private) pathlib ABCs, we add a new `ParserBase.splitext()` method
that splits a path into a `(root, ext)` pair, like `os.path.splitext()`.
This method is called by `PurePathBase.stem`, `suffix`, etc. In a future
version of pathlib, we might make these base classes public, and so users
will be able to define their own `splitext()` method to control file
extension splitting.

In `pathlib.PurePath` we add optimised `stem`, `suffix` and `suffixes`
properties that don't use `splitext()`, which avoids computing the path
base name twice.

gh-119560: Drop an Invalid Assert in PyState_FindModule() (gh-119561) 
The assertion was added in gh-118532 but was based on the invalid assumption that PyState_FindModule() would only be called with an already-initialized module def.  I've added a test to make sure we don't make that assumption again.

gh-119105: Differ.compare is too slow [for degenerate cases] (#119492) 
``_fancy_replace()`` is no longer recursive. and a single call does a worst-case linear number of ratio() computations instead of quadratic. This renders toothless a universe of pathological cases. Some inputs may produce different output, but that's rare, and I didn't find a case where the final diff appeared to be of materially worse quality. To the contrary, by refusing to even consider synching on lines "far apart", there was more easy-to-digest locality in the output.

GH-119496: accept UTF-8 BOM in .pth files (GH-119503) 
`Out-File -Encoding utf8` and similar commands in Windows Powershell 5.1 emit
UTF-8 with a BOM marker, which the regular `utf-8` codec decodes incorrectly.

`utf-8-sig` accepts a BOM, but also works correctly without one.

This change also makes .pth files match the way Python source files are handled.
