Have multiprocessing.freeze_support() enable on spawn, not just win32.

The SyncManager provided support for various data structures such as dict, list, and queue, but oddly, not set.
This introduces support for set by defining SetProxy and registering it with SyncManager.

Change the default multiprocessing start method away from fork to forkserver or spawn on the remaining platforms where it was fork. See the issue for context. This makes the default far more thread safe (other than for people spawning threads at import time... - don't do that!).

Document the `os.fork` posix threads detected `DeprecationWarning` in 3.12 What's New, os, multiprocessing, and concurrent.futures docs.

This starts the process. Users who don't specify their own start method
and use the default on platforms where it is 'fork' will see a
DeprecationWarning upon multiprocessing.Pool() construction or upon
multiprocessing.Process.start() or concurrent.futures.ProcessPool use.
See the related issue and documentation within this change for details.
Fix backslashes in AF_PIPE (#88355)
The correct syntax for AF_PIPE addresses is `\\.\pipe\blahblah`, not `\.\pipe{blahblah}`, but the syntax markup messed up the backslashes.
API members documented in sphinx have an object name, which allow the
documentation to be linked from other projects. Sphinx calculates the
object name by prefixing the current module name to the directive
argument, e.g:
.. module:: foo
.. function:: bar.baz
becomes foo.bar.baz. Since these anchors aren't displayed in the
documentation, some mistakes have crept in, namely the Python stdlib
documentation currently contains the objects:
* asyncio.asyncio.subprocess.DEVNULL
* asyncio.asyncio.subprocess.PIPE
* asyncio.asyncio.subprocess.STDOUT
* asyncio.asyncio.subprocess.Process
* multiprocessing.sharedctypes.multiprocessing.Manager
* xml.etree.ElementTree.xml.etree.ElementInclude
This commit fixes this by making use of the :module: option which
without an argument makes sphinx take the directive argument as is
for the object name (avoiding the prefixing of the current module
name that led to these broken object names).
