pycompat: add bytestr wrapper which mostly acts as a Python 2 str This allows us to handle bytes in mostly the same manner as Python 2 str, so we can get rid of ugly s[i:i + 1] hacks: s = bytestr(s) while i < len(s): c = s[i] ... This is the simpler version of the previous RFC patch which tried to preserve the bytestr type if possible. New version simply drops the bytestr wrapping so we aren't likely to pass a bytestr to a function that expects Python 3 bytes.
