Original commit message from CVS: * gst/base/gstbasesink.c: (gst_base_sink_class_init), (gst_base_sink_wait), (gst_base_sink_do_sync), (gst_base_sink_handle_event): * gst/base/gstbasesink.h: No need to store the clock, the parent element class already has it. * gst/gstbin.c: (gst_bin_set_clock_func), (gst_bin_add_func): Updates for clock_set returning a gboolean * gst/gstclock.c: (gst_clock_entry_new), (gst_clock_id_wait), (gst_clock_id_wait_async), (gst_clock_class_init), (gst_clock_init), (gst_clock_finalize), (gst_clock_get_internal_time), (gst_clock_get_time), (gst_clock_slave_callback), (gst_clock_set_master), (gst_clock_get_master), (do_linear_regression), (gst_clock_add_observation), (gst_clock_set_property), (gst_clock_get_property): * gst/gstclock.h: Implement master/slave. When setting a clock as a slave, a periodic timeout is scheduled to sample master and slave times. Then the slave clock is recalibrated to match offset and rate of the master clock. Update logging a bit. Add flag so that a clock can state that is cannot be slaved to another clock. * gst/gstelement.c: (gst_element_set_clock): * gst/gstelement.h: The set_clock returns a gboolean for when an element cannot deal with the selected clock in the pipeline. * gst/gstpipeline.c: (gst_pipeline_change_state), (gst_pipeline_set_clock): * gst/gstpipeline.h: Handle the case where the selected clock cannot be set on the pipeline. * gst/net/gstnetclientclock.c: (gst_net_client_clock_class_init), (gst_net_client_clock_init), (gst_net_client_clock_finalize), (gst_net_client_clock_set_property), (gst_net_client_clock_get_property), (gst_net_client_clock_observe_times): * gst/net/gstnetclientclock.h: Use regression code in GstClock parent, remove duplicated functionality.
