Original commit message from CVS: * gst/gstbin.c: (gst_bin_init), (gst_bin_add_func), (gst_bin_remove_func), (gst_bin_get_state_func), (gst_bin_element_set_state), (gst_bin_continue_func), (bin_push_state_continue), (bin_handle_async_start), (bin_handle_async_done), (gst_bin_handle_message_func): * gst/gstbin.h: Immediatly commit the toplevel bin state when receiving an async-done message. This enables us to avoid spawning a thread to commit the state in some common cases and it also avoids some races. Avoid spawning a state thread when adding/removing async elements to a toplevel bin. Instead we immediatly update the bin state. Get rid of iterating all the children when getting the state in the bin because it is now always up-to-date. Fix bug where locked elements would always return _SUCCESS even it they returned NO_PREROLL before being locked. Fix the order of the state_change, async-start/done messages that was sometimes incorrect. Mark the state_dirty field as deprecated, we don't need it anymore as we are always up-to-date. * gst/gstelement.c: (gst_element_get_state_func), (gst_element_continue_state): Small debug inprovements. Return the previous element state return when nothing is pending instead of blindly returning SUCCESS. * tests/check/generic/sinks.c: (GST_START_TEST), (pad_blocked_cb), (gst_sinks_suite): Add a whole bunch of new testcases.
