- added macros GST_CLOCK_TIME_IS_VALID and GST_BUFFE_TIMESTAMP_IS_VALID

Browse source 
Original commit message from CVS:
- added macros GST_CLOCK_TIME_IS_VALID and GST_BUFFE_TIMESTAMP_IS_VALID
- use macros in some places
- buffer's timestamp field is a GstClockTime, not a guint64 - this is currently the same, but be sure to only use GstClockTime when working with timestamps in the future
