In order to optimize performance, we fold the 1st and 2nd pass of our
sync strategy into one. They were essentially doing the same thing:
uploading a message to the other side. The only difference was that in
one case we have a negative UID locally, and in the other case, we have
a positive one already.
This saves some time, as we don't have to run through that function on
IMAP servers anyway (they always have positive UIDs), and 2nd were we
stalling further copying until phase 1 was finished. So uploading a
single new message would prevent us from starting to copy existing
regular messages.

We are calling getmessagelist() internally a lot, e.g. just to check if
a UID exists (from uidexist()). This is a very expensive operation in
the UIDMapped case, as we reconstruct the whole messagelist dict every
single time, involving lots of copying etc.
So we provide more efficient implementations for the uidexists()
getmessageuidlist() and getmessagecount() functions that are fast in the
UIDMapped case. This should solve the performance regression that was
recently observed in the Mapped UID case.

- Some documentation improvements, this is a severely underdocumented
class. This still needs some further improvements though.
- Don't use apply(Baseclass) (which is going away in Python 3), use
IMAPFolder.__init__(self, *args, **kwargs).
- Don't call ValueError, string. It is ValueError(string)

Code was broken, as these backends import UIBase (which had been moved).
However, they don't use it, so we can just delete the import.
Sorry, I failed to find those earlier somehow.

The attached patch adds syncing the INTERNALDATE of IMAP folders with
the mtime of messages in maildir folders.
I want this to happen, because I'm running a dovecot over the maildirs
synced by offlineimap, and that uses the mtime as the INTERNALDATE.
When using mutt to view messages I generally sort based on the received
date, which for IMAP folders is the INTERNALDATE.
Since this is the first real coding I've done in Python the patch may
need to be cleaned up some, but it's working pretty well for me. I've
added new messages to each side, and the received date has been
preserved going both ways.
