A previous commit broke a check in sysconfig when building cpython itself.
This caused builds of the standard library modules to search a wrong
location (the installed location rather than the source directory) for
header files with the net effect that a ``make install``
incorrectly caused all extension modules to be rebuilt again and
with incorrect include file paths.
When building Python, we need two distinct "include" directories:
- source .h files
- install target for .h files
Note that this doesn't matter except when building Python from source.
Historically:
- source .h files were in the distutils scheme under 'include'
- the install directory was in the distutils.command.install scheme
under 'headers'
GH-24549 merged these; sysconfig is now the single source of truth and
distutils is derived from it.
This commit introduces a "secret" scheme path, 'headers', which contains
the install target. It is only present when building Python.
The distutils code uses it if present, and falls back to 'include'.

Only complain if the config target is >= 10.3 and the current target is
< 10.3. The check was originally added to ensure that incompatible
LDSHARED flags are not used, because -undefined dynamic_lookup is
used when building for 10.3 and later, and is not supported on older OS
versions. Apart from that, there should be no problem in general
with using an older target.

This change:
* merges `distutils.sysconfig` into `sysconfig` while keeping the original functionality and
* marks `distutils.sysconfig` as deprecated
https://bugs.python.org/issue41282
With this patch, `distutils.command.install.INSTALL_SCHEMES` are loaded from
`sysconfig._INSTALL_SCHEMES`.
The distutils module is deprecated and will be removed in 3.12 (PEP 632).
This change makes the `sysconfig._INSTALL_SCHEMES` the single point of truth
for install schemes while keeping `distutils.command.install.INSTALL_SCHEMES`
exactly the same. If we, during the transition to the sysconfig, change
something, this makes sure that it also propagates to distutils until the
module gets removed.
Moreover, as discussed [on Discourse], Linux distros need to patch
distutils/sysconfig to make sure the packages will land in proper locations.
This patch makes it easier because it leaves only one location where install
schemes are defined which is much easier to patch/adjust.
[on Discourse]: https://discuss.python.org/t/pep-632-deprecate-distutils-module/5134
The implementation is slightly different than the plan but I think it's the
easiest way how to do it and it also makes the downstream patch simple,
flexible and easy to maintain.
It's also necessary to implement this before setuptools starts bundling
the distutils module so the default install schemes stay in the standard library.
The removed code from sysconfig does not seem to have any negative effect
because, honestly, it seems that nothing actually uses the install schemes
from sysconfig at all. There were many big changes in these modules where
they were trying to include packaging in stdlib and then reverted that.
Also, the test of distutils install command does not count with the different
locations which is good evidence that the reason to have this piece of code
is no longer valid.

The following changes are required:
* add a new platform win-arm64
* replace the emulated compiler executable paths
* bump the linker base addressed as ARM64 requires more memory
this change might not be needed (investigation required)
On Windows 10 ARM64, VS compiler paths look like this:
C:\Program Files (x86)\Microsoft Visual
Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\HostX86\ARM64\cl.exe
Note that the cl.exe for ARM64 is an x32 binary, which can run emulated
on Windows 10 ARM64 (it has builtin emulation for x32).
The rc.exe and mc.exe paths have to also be changed, as the initial
discovery has to be fixed.
Work in progress to remove the hardcoded bits and to change the path
query fixes to the proper location.

The distutils bdist_wininst command deprecated in Python 3.8 has been
removed. The distutils bidst_wheel command is now recommended to
distribute binary packages on Windows.
* Remove Lib/distutils/command/bdist_wininst.py
* Remove PC/bdist_wininst/ project
* Remove Lib/distutils/command/wininst-*.exe programs
* Remove all references to bdist_wininst
macOS releases numbering has changed as of macOS 11 Big Sur. Previously, major releases were of the form 10.x, 10.x+1, 10.x+2, etc; as of Big Sur, they are now x, x+1, etc, so, for example, 10.15, 10.15.1, ..., 10.15.7, 11, 11.0.1, 11.1, ..., 12, 12.1, etc. Allow Python to build with single-digit deployment target values. Patch provided by FX Coudert.
On macOS system provided libraries are in a shared library cache
and not at their usual location. This PR teaches distutils to search
in the SDK, even if there was no "-sysroot" argument in
the compiler flags.

* Add support for macOS 11 and Apple Silicon (aka arm64)
As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy
* Support building on recent versions of macOS while deploying to older versions
This allows building installers on macOS 11 while still supporting macOS 10.9.
Fix test_copyreg when numpy is installed: test.pickletester now
saves/restores warnings.filters when importing numpy, to ignore
filters installed by numpy.
Add the save_restore_warnings_filters() function to the
test.support.warnings_helper module.
- Fix upload test on systems that blocks MD5
- Add SHA2-256 and Blake2b-256 digests based on new Warehous and twine
specs.

distutils.tests now saves/restores warnings filters to leave them
unchanged. Importing tests imports docutils which imports
pkg_resources which adds a warnings filter.
It is possible to use either '-isysroot /some/path' (with a space) or
'-isysroot/some/path' (no space in between). Support both forms in
places where special handling of -isysroot is done, rather than just
the first form.

Add --with-platlibdir option to the configure script: name of the
platform-specific library directory, stored in the new sys.platlitdir
attribute. It is used to build the path of platform-specific dynamic
libraries and the path of the standard library.
It is equal to "lib" on most platforms. On Fedora and SuSE, it is
equal to "lib64" on 64-bit systems.

Reimplement distutils.spawn.spawn() function with the subprocess
module.
setup.py now uses a basic implementation of the subprocess module if
the subprocess module is not available: before required C extension
modules are built.
When checking `setup.py` and when the `author` field was provided, but
the `author_email` field was missing, erroneously a warning message was
displayed that the `author_email` field is required.
The specs do not require the `author_email`field:
https://packaging.python.org/specifications/core-metadata/#author
The same is valid for `maintainer` and `maintainer_email`.
The warning message has been adjusted.

Provides a richer platform tag for AIX that we expect to be sufficient for PEP 425
binary distribution identification. Any backports to earlier Python versions will be
handled via setuptools.
