* Add mimalloc v2.12 Modified src/alloc.c to remove include of alloc-override.c and not compile new handler. Did not include the following files: - include/mimalloc-new-delete.h - include/mimalloc-override.h - src/alloc-override-osx.c - src/alloc-override.c - src/static.c - src/region.c mimalloc is thread safe and shares a single heap across all runtimes, therefore finalization and getting global allocated blocks across all runtimes is different. * mimalloc: minimal changes for use in Python: - remove debug spam for freeing large allocations - use same bytes (0xDD) for freed allocations in CPython and mimalloc This is important for the test_capi debug memory tests * Don't export mimalloc symbol in libpython. * Enable mimalloc as Python allocator option. * Add mimalloc MIT license. * Log mimalloc in Lib/test/pythoninfo.py. * Document new mimalloc support. * Use macro defs for exports as done in: https://github.com/python/cpython/pull/31164/ Co-authored-by: Sam Gross <colesbury@gmail.com> Co-authored-by: Christian Heimes <christian@python.org> Co-authored-by: Victor Stinner <vstinner@python.org>
