The path is split on '/' and put back together again using the current
directory separator. Needed because filenames in the setup script are
always supplied in Unix style, and have to be converted to the local
convention before we can actually use them in the filesystem. Raises
ValueError on non-Unix-ish systems if 'pathname' either starts or
ends with a slash.

Return the default base location for distlib caches. If the directory does
not exist, it is created. Use the suffix provided for the base directory,
and default to '.distlib' if it isn't provided.
On Windows, if LOCALAPPDATA is defined in the environment, then it is
assumed to be a directory, and will be the parent directory of the result.
On POSIX, and on Windows if LOCALAPPDATA is not defined, the user's home
directory - using os.expanduser('~') - will be the parent directory of
the result.
The result is just the directory '.distlib' in the parent directory as
determined above, or with the name specified with ``suffix``.

This is called to create a connection instance. Normally you'd
pass a connection class to do_open, but it doesn't actually check for
a class, and just expects a callable. As long as we behave just as a
constructor would have, we should be OK. If it ever changes so that
we *must* pass a class, we'll create an UnsafeHTTPSConnection class
which just sets check_domain to False in the class definition, and
choose which one to pass to do_open.
