pycompat: custom implementation of urllib.parse.quote()...

pycompat: custom implementation of urllib.parse.quote() urllib.parse.quote() accepts either str or bytes and returns str. There exists a urllib.parse.quote_from_bytes() which only accepts bytes. We should probably use that to retain strong typing and avoid surprises. In addition, since nearly all strings in Mercurial are bytes, we probably don't want quote() returning unicode. So, this patch implements a custom quote() that only accepts bytes and returns bytes. The quoted URL should only contain URL safe characters which is a strict subset of ASCII. So `.encode('ascii', 'strict')` should be safe.
