Original commit message from CVS: * gst/gstthread.c: (gst_thread_dispose), (gst_thread_sync), (gst_thread_change_state), (gst_thread_child_state_change), (gst_thread_main_loop): * gst/gstthread.h: * testsuite/threads/Makefile.am: * testsuite/threads/queue.c: * testsuite/threads/thread.c: (construct_pipeline), (change_state), (main): * testsuite/threads/threadc.c: (construct_pipeline): * testsuite/threads/threadd.c: (main): * testsuite/threads/threade.c: (main): * testsuite/threads/threadf.c: Reworked the GstThread implementation, make more operations threadsafe and more reliable. Moved testcases from the failing to the working list.
