Rip out all codecs that can't work in a unicode/bytes world:

Browse source 
base64, uu, zlib, rot_13, hex, quopri, bz2, string_escape.

However codecs.escape_encode() and codecs.escape_decode()
still exist, as they are used for pickling str8 objects
(so those two functions can go, when the str8 type is removed).
