bpo-35903: Use autoconfig to probe for shm_open() and shm_unlink(). (#11765)
Use autoconfig to probe for shm_open() and shm_unlink().  Set SHM_NEEDS_LIBRT if we must
link with librt to get the shm_* functions.  Change setup.py to use the autoconfig defines.  These
changes should make it more likely that _multiprocessing/posixshmem.c gets built correctly on
different platforms.

bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373)
Use crypt_r() when available instead of crypt() in the crypt module.

As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.

stratakis cf10a750f4 bpo-35257: Avoid leaking LTO linker flags into distutils (GH-10900)
When compiling 3rd party C extensions, the linker flags used by the
compiler for the interpreter and the stdlib modules, will get
leaked into distutils. In order to avoid that, the PY_CORE_LDFLAGS
and PY_LDFLAGS_NODIST are introduced to keep those flags separated.

stratakis f92c7aa1ae bpo-35351: Pass link time optimization flags to CFLAGS_NODIST (GH-10797)
When using link time optimizations, the -flto flag is passed to
BASECFLAGS, which makes it propagate to distutils. Those flags
should be reserved for the interpreter and the stdlib extension
modules only, thus moving those flags to CFLAGS_NODIST.

bpo-35214: Initial clang MemorySanitizer support (GH-10479)
Adds configure flags for msan and ubsan builds to make it easier to enable.
These also encode the detail that address sanitizer and memory sanitizer
should disable pymalloc.

Define MEMORY_SANITIZER when appropriate at build time and adds workarounds
to existing code to mark things as initialized where the sanitizer is otherwise unable to
determine that.  This lets our build succeed under the memory sanitizer.  not all tests
pass without sanitizer failures yet but we're in pretty good shape after this.

serge-sans-paille 5ad36f9b21 bpo-28015: Support LTO build with clang (GH-9908)
.o generated by clang in LTO mode actually are LLVM bitcode files, which
leads to a few errors during configure/build step:

- add lto flags to the BASECFLAGS instead of CFLAGS, as CFLAGS are used
  to build autoconf test case, and some are not compatible with clang LTO
  (they assume binary in the .o, not bitcode)
- force llvm-ar instead of ar, as ar is not aware of .o files generated
  by clang -flto

bpo-32726: macOS installer and framework enhancements and changes for 3.7.0 (GH-5448)
This issue covers various changes for the macOS installers provided via python.org for 3.7.0.

- Provide a provisional new installer variant for macOS 10.9 and later systems with 64-bit (x86_64) architecture only.  Apple has made it known that future versions of macOS will only fully support 64-bit executables and some other third-party software suppliers have chosen 10.9 as their oldest supported system.
 
- Support **Tcl/Tk 8.6** with the 10.9 installer variant.
 
- Upgrade **OpenSSL** to 1.1.0g and **SQLite** to 3.22.0.
 
- The compiler name used for the interpreter build and for modules built with **Distutils / pip** is now _gcc_ rather than _gcc-4.2_. And extension module builds will no longer try to force use of an old SDK if present.

bpo-31429: Define TLS cipher suite on build time (#3532)
Until now Python used a hard coded white list of default TLS cipher
suites. The old approach has multiple downsides. OpenSSL's default
selection was completely overruled. Python did neither benefit from new
cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites.
For example we used to re-enable 3DES.

Python now defaults to OpenSSL DEFAULT cipher suite selection and black
lists all unwanted ciphers. Downstream vendors can override the default
cipher list with --with-ssl-default-suites.

bpo-32598: Use autoconf to detect usable OpenSSL (#5242)
Add https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html

OpenSSL extensions. The M4 macro uses pkg-config and falls back to
manual detection.

Add autoconf magic to detect usable X509_VERIFY_PARAM_set1_host()
and related functions.

Refactor setup.py to use new config vars to compile _ssl and _hashlib
modules.

Starting with AIX6.1 there is support in libc.a for uuid (RFC4122)
This patch provides the changes needed for this integration with the OS.

On AIX the base function is uuid_create() rather than uuid_generate_time()
The AIX uuid_t typedef is more aligned to the UUID field based definition
while the Linux typedef that is more aligned with UUID bytes
(or perhaps UUID bytes_le) definitions.
