Original commit message from CVS: - Removed unused locking from the cothreads - use G_*_DECLS in .h files - remove gstlog.h include from gstobject.h, add to .c files - removed unused refcounting code from gstobject - small fixes in #includes - Added Scheduling policy and priority properties to gstthread so that SCHED_FIFO and SCHED_RR threads can be constructed.
