Subject: Port ctypes and system libffi patches for arm64/macOS 10.15+ to Python 3.7.12
This ports the following ctypes and libffi pyenv patches for Python
2.7.18 to Python 3.7.12:
* `0004-Use-system-libffi-for-Mac-OS-10.15-and-up.patch`
* `0005-ctypes-use-the-correct-ABI-for-variadic-functions.patch`
* `0006-ctypes-probe-libffi-for-ffi_closure_alloc-and-ffi_pr.patch`
These patches enable use of system libffi (fixing a broken `ctypes`
module on arm64 targets) and enable calling variadic functions on arm64.
They've been combined from patches port from Homebrew to pyenv by Takumi
Sueda, updated to work on the Python 3.7.12 codebase.
The Homebrew patches are themselves backports of changes in Python 3.9
and 3.10. That patch can be found at:
https://github.com/Homebrew/formula-patches/blob/master/python/3.8.7.patch
