lib: Rework interface for maildir_flags synchronization

Instead of having an API for setting a library-wide flag for
synchronization (notmuch_database_set_maildir_sync) we instead
implement maildir synchronization with two new library functions:

	notmuch_message_maildir_flags_to_tags
  and   notmuch_message_tags_to_maildir_flags

These functions are nicely documented here, (though the implementation
does not quite match the documentation yet---as plainly evidenced by
the current results of the test suite).
