Wim Taymans 74ca793b0a Clock fixes. Added async callbacks and clock unscheduling.
Original commit message from CVS:
Clock fixes. Added async callbacks and clock unscheduling.
Threading fixes. Fixed race condition in GstTask and possible
deadlock in _pad_get_caps(). Made various subsystems (query,
format,..) threadsafe.
Lots of cleanups and documentation.
