The above is now done. Mainly because seeking backwards in bzip2
compressed mails was broken.

Done also.

This isn't done.. I've a separate
http://hg.dovecot.org/dovecot-2.0-sslstream/ that does ssl proxying with
ssl iostreams. It's probably easier to change to support compression
proxying as well. Lets see if I can manage to do that now.. Anyway that
code would be merged only for v2.1, since it changes things so much.
