lib: Add an iterator over all messages in a thread

Previously, getting the list of all messages in a thread required
recursively traversing the thread's message hierarchy, which was both
difficult and resulted in messages being out of order.  This adds a
public function to retrieve an iterator over all of the messages in a
thread in oldest-first order.
