• dovecot-auth talks now ASCII based protocol. this makes it easy to write complete replacement auth server if someone wants to do something weird. I also thought maybe Postfix could be made to talk that (or similiar) protocol as well, but no-one has answered my mail about it so far. Perhaps I should just write binary compatible libsasl2 which actually talks to dovecot-auth.
• other authentication code cleanups
• don't insert extra spaces at the beginning of FETCH replies (I guess most clients ignored them)
• mbox fixes
• some index fixes
• Hopefully fixes _send_istream() assert crash with FreeBSD (sendfile() was used wrong)

The authentication code changes haven't been tested too much. I only tried that PLAIN authentication works. Others might not.
