Support byte and byte string literals

A byte literal is an u8 created as a ascii char or hex escape
e.g. b'X'.  A byte string literal is a string created from ascii or
hex chars. bytes are represented as u8 and byte strings as str (with
just ascii < 256 chars), but it should really be &'static [u8; n].
