bpo-43908: Make heap types converted during 3.10 alpha immutable (GH-26351) (GH-26766)
* Make functools types immutable * Multibyte codec types are now immutable * pyexpat.xmlparser is now immutable * array.arrayiterator is now immutable * _thread types are now immutable * _csv types are now immutable * _queue.SimpleQueue is now immutable * mmap.mmap is now immutable * unicodedata.UCD is now immutable * sqlite3 types are now immutable * _lsprof.Profiler is now immutable * _overlapped.Overlapped is now immutable * _operator types are now immutable * winapi__overlapped.Overlapped is now immutable * _lzma types are now immutable * _bz2 types are now immutable * _dbm.dbm and _gdbm.gdbm are now immutable (cherry picked from commit 00710e6) Co-authored-by: Erlend Egeberg Aasland <[email protected]> Co-authored-by: Erlend Egeberg Aasland <[email protected]>
