Initial commit for ticket #937: Revamping of presence management to make it more efficient

Presence enhancements:
 - finer grained buddy lock object, instead of using global PJSUA-LIB's mutex
 - individual resubscription timer for buddies and also add random delay interval so that resubscriptions don't happen simultaneously (may hog processing and bandwidth).
 - in general reduced the use of global PJSUA-LIB's mutex for more efficiency
 - added last termination code in buddy info
 - use the RPID note's text for buddy's offline status rather than the default "offline" status, if available
 - resubscribe automatically on several termination causes as explained in the ticket (still untested)

General enhancements:
 - added pjsua_schedule_timer() and pjsua_cancel_timer() APIs
