`isinstance()` influence whether `issubclass()` raises an exception (#104559)

During the PEP 695 implementation at one point I made
TypeVar.__name__ return garbage, and all of test_typing passed.
So I decided to add a few more tests. In the process I discovered
a minor incompatibility from the C implementation of TypeVar:
empty constraints were returned as None instead of an empty tuple.

`urllib.parse.urlsplit` has already been respecting the WHATWG spec a bit #25595.
This adds more sanitizing to respect the "Remove any leading C0 control or space from input" [rule](https://url.spec.whatwg.org/#url-parsing:~:text=Remove%20any%20leading%20and%20trailing%20C0%20control%20or%20space%20from%20input.) in response to [CVE-2023-24329](https://nvd.nist.gov/vuln/detail/CVE-2023-24329).

(#103863)
Fix Zip64 extensions not being properly applied in some cases:
Fixes an issue where adding a small file to a `ZipFile`
object while forcing zip64 extensions causes an extra Zip64 record to be
added to the zip, but doesn't update the `min_version` or file sizes in
the primary central directory header.
Also fixed an edge case in checking if zip64 extensions are required:
This fixes an issue where if data requiring zip64 extensions was added
to an unseekable stream without specifying `force_zip64=True`, zip64
extensions would not be used and a RuntimeError would not be raised when
closing the file (even though the size would be known at that point).
This would result in successfully writing corrupt zip files.
Deciding if zip64 extensions are required outside of the `FileHeader`
function means that both `FileHeader` and `_ZipWriteFile` will always be
in sync. Previously, the `FileHeader` function could enable zip64
extensions without propagating that decision to the `_ZipWriteFile`
class, which would then not correctly write the data descriptor record
or check for errors on close.
If anyone is actually using `ZipInfo.FileHeader` as a public API without
explicitly passing True or False in for zip64, their own code may still be
susceptible to that kind of bug unless they make a similar change to
where the zip64 decision happens.
Fixes #103861

(#104248)
Add http.client.HTTPConnection method get_proxy_response_headers() - this is a followup to https://github.com/python/cpython/pull/26152 which added it as a non-public attribute. This way we don't pre-compute a headers dictionary that most users will never access. The new method is properly public and documented and triggers full proxy header parsing into a dict only when actually called.

This implements PEP 695, Type Parameter Syntax. It adds support for:
- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

Use `Path.walk()` to implement the recursive wildcard `**`. This method
uses an iterative (rather than recursive) walk - see GH-100282.

zoneinfo tests (#22863)
These are stubs to be used for adding hypothesis (https://hypothesis.readthedocs.io/en/latest/) tests to the standard library.
When the tests are run in an environment where `hypothesis` and its various dependencies are not installed, the stubs will turn any tests with examples into simple parameterized tests and any tests without examples are skipped.
It also adds hypothesis tests for the `zoneinfo` module, and a Github Actions workflow to run the hypothesis tests as a non-required CI job.
The full hypothesis interface is not stubbed out — missing stubs can be added as necessary.

(GH-104387)
When monitoring LINE events, instrument all instructions that can have a predecessor on a different line.
Then check that the a new line has been hit in the instrumentation code.
This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.

`pathlib.Path.glob()` now suppresses all OSError exceptions, except
those raised from calling `is_dir()` on the top-level path.
Previously, `glob()` suppressed ENOENT, ENOTDIR, EBADF and ELOOP
errors and their Windows equivalents. PermissionError was also
suppressed unless it occurred when calling `is_dir()` on the
top-level path. However, the selector would abort prematurely
if a PermissionError was raised, and so `glob()` could return
incomplete results.

This PR removes `_Py_dg_stdnan` and `_Py_dg_infinity` in favour of
using the standard `NAN` and `INFINITY` macros provided by C99.
This change has the side-effect of fixing a bug on MIPS where the
hard-coded value used by `_Py_dg_stdnan` gave a signalling NaN
rather than a quiet NaN.

Stop de-duplicating results in `_RecursiveWildcardSelector`. A new
`_DoubleRecursiveWildcardSelector` class is introduced which performs
de-duplication, but this is used _only_ for patterns with multiple
non-adjacent `**` segments, such as `path.glob('**/foo/**')`. By avoiding
the use of a set, `PurePath.__hash__()` is not called, and so paths do not
need to be stringified and case-normalised.
Also merge adjacent '**' segments in patterns.
