gh-71052: Fix several Android build issues (#115955)
This change is part of the work on PEP-738: Adding Android as a 
supported platform.

* Remove the "1.0" suffix from libpython's filename on Android, which 
  would prevent Gradle from packaging it into an app. 
* Simplify the build command in the Makefile so that libpython always 
  gets given an SONAME with the `-Wl-h` argument, even if the SONAME is
  identical to the actual filename.
* Disable a number of functions on Android which can be compiled and 
  linked against, but always fail at runtime. As a result, the native
  _multiprocessing module is no longer built for Android.
* gh-115390 (bee7bb331) added some pre-determined results to the 
  configure script for things that can't be autodetected when
  cross-compiling; this change adds Android to these where appropriate.
* Add a couple more pre-determined results for Android, and making them 
  cover iOS as well. This means the --enable-ipv6 configure option will 
  no longer be required on either platform.

gh-111225: Link extension modules against libpython on Android (#115780)
Part of the work on PEP 738: Adding Android as a supported platform.

* Rename the LIBPYTHON variable to MODULE_LDFLAGS, to more accurately 
  reflect its purpose.
* Edit makesetup to use MODULE_LDFLAGS when linking extension modules.
* Edit the Makefile so that extension modules depend on libpython on 
  Android and Cygwin.
* Restore `-fPIC` on Android. It was removed several years ago with a 
  note that the toolchain used it automatically, but this is no longer
  the case. Omitting it causes all linker commands to fail with an error
  like `relocation R_AARCH64_ADR_PREL_PG_HI21 cannot be used against
  symbol '_Py_FalseStruct'; recompile with -fPIC`.

gh-114099: Refactor configure and Makefile to accomodate non-macOS frameworks (#115120)
Part of the PEP 730 work to add iOS support.

This change lays the groundwork for introducing iOS/tvOS/watchOS 
frameworks; it includes the structural refactoring needed so that iOS
branches can be added into in a subsequent PR.

Summary of changes:
* Updates config.sub to the 2024-01-01 release. This is the "as 
  released" version of config.sub.
* Adds a RESSRCDIR variable to allow sharing of macOS and iOS Makefile 
  steps.
* Adds an INSTALLTARGETS variable so platforms can customise which
  targets are actually installed. This will be used to exclude certain
  targets (e.g., binaries, manfiles) from iOS framework installs.
* Adds a PYTHONFRAMEWORKINSTALLNAMEPREFIX variable; this is used as
  the install name for the library. This is needed to allow for iOS
  frameworks to specify an @rpath-based install name.
* Evaluates MACHDEP earlier in the configure process so that
  ac_sys_system is available.
* Modifies _PYTHON_HOST_PLATFORM evaluation for cross-platform builds
  so that the CPU architecture is differentiated from the host
  identifier. This will be used to generate a _PYTHON_HOST_PLATFORM
  definition that includes ABI information, not just CPU architecture.
* Differentiates between SOABI_PLATFORM and PLATFORM_TRIPLET.
  SOABI_PLATFORM is used in binary module names, and includes the ABI,
  but not the OS or CPU architecture (e.g.,
  math.cpython-313-iphonesimulator.dylib). PLATFORM_TRIPLET is used
  as the sys._multiarch value, and on iOS will contains the ABI and
  architecture (e.g., iphoneos-arm64). This differentiation hasn't
  historically been needed because while macOS is a multiarch platform,
  it uses a bare darwin as PLATFORM_TRIPLE.
* Removes the use of the deprecated -Wl,-single_module flag when
  compiling macOS frameworks.
* Some whitespace normalisation where there was a mix of spaces and tabs 
  in a single block.

gh-112970: Detect and use closefrom() when available (#112969)
glibc-2.34 implements closefrom(3) using the same semantics as on BSD.
Check for closefrom() in configure and use the check result in
fileutils.c, rather than hardcoding a FreeBSD check.

Some implementations of closefrom() return an int. Explicitly discard 
the return value by casting it to void, to avoid future compiler
warnings.

gh-90815: Add mimalloc memory allocator (#109914)
* 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:

gh-108724: Add PyMutex and _PyParkingLot APIs (gh-109344)
PyMutex is a one byte lock with fast, inlineable lock and unlock functions for the common uncontended case.  The design is based on WebKit's WTF::Lock.

PyMutex is built using the _PyParkingLot APIs, which provides a cross-platform futex-like API (based on WebKit's WTF::ParkingLot).  This internal API will be used for building other synchronization primitives used to implement PEP 703, such as one-time initialization and events.

This also includes tests and a mini benchmark in Tools/lockbench/lockbench.py to compare with the existing PyThread_type_lock.

Uncontended acquisition + release:
* Linux (x86-64): PyMutex: 11 ns, PyThread_type_lock: 44 ns
* macOS (arm64): PyMutex: 13 ns, PyThread_type_lock: 18 ns
* Windows (x86-64): PyMutex: 13 ns, PyThread_type_lock: 38 ns

PR Overview:

The primary purpose of this PR is to implement PyMutex, but there are a number of support pieces (described below).

* PyMutex:  A 1-byte lock that doesn't require memory allocation to initialize and is generally faster than the existing PyThread_type_lock.  The API is internal only for now.
* _PyParking_Lot:  A futex-like API based on the API of the same name in WebKit.  Used to implement PyMutex.
* _PyRawMutex:  A word sized lock used to implement _PyParking_Lot.
* PyEvent:  A one time event.  This was used a bunch in the "nogil" fork and is useful for testing the PyMutex implementation, so I've included it as part of the PR.
* pycore_llist.h:  Defines common operations on doubly-linked list.  Not strictly necessary (could do the list operations manually), but they come up frequently in the "nogil" fork. ( Similar to https://man.freebsd.org/cgi/man.cgi?queue)

gh-106213: Make Emscripten trampolines work with JSPI (GH-106219)
There is a WIP proposal to enable webassembly stack switching which have been
implemented in v8:

https://github.com/WebAssembly/js-promise-integration

It is not possible to switch stacks that contain JS frames so the Emscripten JS
trampolines that allow calling functions with the wrong number of arguments
don't work in this case. However, the js-promise-integration proposal requires
the [type reflection for Wasm/JS API](https://github.com/WebAssembly/js-types)
proposal, which allows us to actually count the number of arguments a function
expects.

For better compatibility with stack switching, this PR checks if type reflection
is available, and if so we use a switch block to decide the appropriate
signature. If type reflection is unavailable, we should use the current EMJS
trampoline.

We cache the function argument counts since when I didn't cache them performance
was negatively affected.

gh-109054: configure checks if libatomic is needed (#109101)
Fix building the _testcapi extension on Linux AArch64 which requires
linking to libatomic when <cpython/pyatomic.h> is used: the
_Py_atomic_or_uint64() function requires libatomic
__atomic_fetch_or_8() on this platform.

The configure script now checks if linking to libatomic is needed and
generates a new LIBATOMIC variable used to build the _testcapi
extension.

Building the _testcapi extension now uses the LIBATOMIC variable in
its LDFLAGS, since Modules/_testcapi/pyatomic.c uses
<cpython/pyatomic.h>.
