Add internal functions for manipulating a new notmuch_message_t

Browse source 
This will support the add_message function in incrementally creating
state in a new notmuch_message_t. The new functions are

      _notmuch_message_set_filename
      _notmuch_message_add_thread_id
      _notmuch_message_ensure_thread_id
      _notmuch_message_set_date
      _notmuch_message_sync
