Only significant implementation specific code at the moment is FILE-SIZE
which isn't very important. We can also easily implement it for CCL.
Additionally, we clean up an unused lexical variable warning and remove
a duplicate definiton of MIME-TYPE-STRING fro MIME-UNKNOWN-PART that CCL
doesn't like.
