Although this patch contains API changes and is rather weighty for an
RC phase, the mailbox module was essentially unusable without the patch
since it would produce UnicodeErrors when handling non-ascii input
at arbitrary and somewhat mysterious places, and any non-trivial amount
of email processing will encounter messages with non-ascii bytes.
The release manager approved the patch application.
The changes allow binary input, and reject non-ASCII string input early
with a useful message instead of failing mysteriously later. Binary
is used internally for reading and writing the mailbox files. StringIO
and Text file input are deprecated.

Also made similar changes to deque.reverse() though this wasn't
strictly necessary (the edge case cannot occur with two pointers
moving to meet in the middle). Making the change in reverse()
was more a matter of future-proofing.

incoming headers which makes this behaviour now consistent in both incoming and
outgoing direction.
