[notmuch] [PATCH] Added regress option to threads iterator
Added the functions notmuch_threads_regress and notmuch_threads_is_first to
notmuch library. With them is possible to iterate backwards on threads.
* notmuch_threads_regress do the opposite than notmuch_threads_advance,
getting the threads iterator one position backwards.
* notmuch_threads_is_first return TRUE if the iterator is in the first
thread.
