Previously, if you passed in a bytes object, it would create a whole
new object.

There's no bufsize argument anymore, and os.fdopen() is only a very
thin wrapper around open() anymore. Change the documentation to
reflect that.

There is a rare edge case where the filesystem used by the tempfile functions
(usually /tmp) doesn't support xattrs while the one used by TESTFN (the current
directory, so likely to be below /home) does. This causes the xattr related
test_shutil tests fail. skip_unless_xattr now checks both.

I have also added skip_unless_xattr to __all__ where it has been missing.

Closes #14864: Added documentation on how to undo the effects of a logging.disable() call. Thanks to user Guillaume for the suggestion.

If a dependency is expressed both in the .sln file and the .vcxproj file
msbuild is confused.  Removing the .sln dependencies which are
deprecated anyway.  See:
