The new object is simply a linked-list of notmuch_message_t objects, (unlike the old object which contained a couple of Xapian iterators). This works now by the query code immediately iterator over all results and creating notmuch_message_t objects for them, (rather than waiting to create the objects until the notmuch_messages_get call as we did earlier). The point of this change is to allow other instances of lists of messages, (such as in notmuch_thread_t), that are not directly related to Xapian search results.
