Extend the _Py_TYPEOF macro to use __typeof__() with MSVC 17.9 and newer, or decltype() under C++11 and newer.
…H-157180) GH-156003 made ZipExtFile._read1() call decompress(data, max_length) on non-deflate decompressors and consult needs_input before reading more. A decompressor installed by monkey-patching _get_decompressor() (as projects like zipfile-zstd, zipfile-deflate64, ... do) may support neither, and every read through it then failed with AttributeError. - Make LZMADecompressor.needs_input public to simplify implementation. - Make the needs_input attribute optional. - If `decompress()` fails with TypeError, try again with one argument. - Since the fallback to one-argument call is a maintenance burden, raise DeprecationWarning. - Add tests for future changes, so we can make informed decisions about breaking monkey-patchers.

…H-157147) linecache.getline() now works for a .zip archive on sys.path without the caller having to pass module_globals. Callers that only have a file name, such as pdb, warnings, and doctest, now get source. Reads of such files go through the get_data() method of the path entry finder registered for the archive in sys.path_importer_cache. Prior to this: os.stat() would fail on the archive-internal path, the loader lookup needed the globals, and the sys.path search would only handle relative names and assumed a filesystem rather than using an importer.

Add `@vectorcall` as a decorator to Argument Clinic (AC) which generates a new [Vectorcall Protocol](https://docs.python.org/3/c-api/call.html#the-vectorcall-protocol) argument parsing C function named `{}_vectorcall`. This is only supported for `__new__` and `__init__` currently to simplify implementation. The generated code has similar or better performance to existing hand-written cases for `list`, `float`, `str`, `tuple`, `enumerate`, `reversed`, and `int`. Using the decorator added vectorcall to `bytearray` and construction got 1.09x faster. For more details see the comments in gh-87613.
