bpo-37814: Document the empty tuple type annotation syntax (GH-15208)
https://bugs.python.org/issue37814:
> The empty tuple syntax in type annotations, `Tuple[()]`, is not obvious from the examples given in the documentation (I naively expected `Tuple[]` to work); it has been documented in PEP 484 and in mypy, but not in the documentation for the typing module.

The `expand` option was introduced in 2000 in commit fad27aee1.
It appears to have been always set since it was committed, and
what it does is tell the code to do something essential. So,
just always do that, and cut the option.
Also cut the `linebreakprops` option, which isn't consulted anymore.

This file started life as a script, before conversion to a
`unittest` test file. Clear out some legacies of that conversion
that are a bit confusing about how it works.
Most notably, it's unlikely there's still a good reason to try
to recover from `unicodedata` failing to import -- as there was
when that logic was first added, when the module was very new.
So take that out entirely. Keep `self.db` working, though, to
avoid a noisy diff.

This fixes an inconsistency between the Python and C implementations of

bpo-20523: pdb searches for .pdbrc in ~ instead of $HOME (GH-11847)
Previously pdb checked the $HOME environmental variable
to find the user .pdbrc. If $HOME is not set, the user
.pdbrc would not be found.
Change pdb to use `os.path.expanduser('~')` to determine
the user's home directory. Thus, if $HOME is not set (as
in tox or on Windows), os.path.expanduser('~') falls
back on other techniques for locating the user's home
directory.
This follows pip's implementation for loading .piprc.

bpo-36590: Add Bluetooth RFCOMM and support for Windows. (GH-12767)
Support for RFCOMM, L2CAP, HCI, SCO is based on the BTPROTO_* macros
being defined. Winsock only supports RFCOMM, even though it has a
BTHPROTO_L2CAP macro. L2CAP support would build on windows, but not
necessarily work.
This also adds some basic unittests for constants (all of which existed
prior to this commit, just not on windows) and creating sockets.
When building packages (e.g. for openSUSE Linux)
(random) filesystem order of input files
influences ordering of functions in the output .so files.
Thus without the patch, builds (in disposable VMs) would usually differ.

when interpreting stack traces as the file is in a (almost certainly)
incorrect location, and lacks the full relative path to Lib (e.g.
email/mime/image.py will only show image.py).

path so that stack traces are (hopefully) less misleading and more
informative.
