Implement XEP-0198 revision 1.5.2 and limit number of hibernated sessions per user
Revision 1.5.2 allows sending h-values on resumes that fail due to hibernation timeout
and to send out a smacks ack directly before the stream close tag.
I also made the used timers stoppable even for prosody 0.10 and below, this makes
the smacks-ack-delayed event more useful.
