treewide: replace uint32 uids with opaque strings

Add a new models.UID type (an alias to string). Replace all occurrences
of uint32 being used as message UID or thread UID with models.UID.

Update all workers to only expose models.UID values and deal with the
conversion internally. Only IMAP needs to convert these to uint32. All
other backends already use plain strings as message identifiers, in
which case no conversion is even needed.

The directory tree implementation needed to be heavily refactored in
order to accommodate thread UID not being usable as a list index.
