Original commit message from CVS: * check/gst/gstbin.c: (pop_messages), (GST_START_TEST): * check/gst/gstbus.c: (message_func_eos), (message_func_app), (send_messages), (GST_START_TEST), (gstbus_suite): * check/gst/gstpipeline.c: (GST_START_TEST): * check/pipelines/cleanup.c: (run_pipeline): * check/pipelines/simple_launch_lines.c: (run_pipeline), (GST_START_TEST): * gst/gstbus.c: (gst_bus_have_pending), (gst_bus_source_prepare), (gst_bus_source_check), (gst_bus_source_dispatch), (gst_bus_create_watch), (gst_bus_add_watch_full), (gst_bus_add_watch), (poll_func), (poll_timeout), (gst_bus_poll): * gst/gstbus.h: * tools/gst-launch.c: (event_loop): * tools/gst-md5sum.c: (event_loop): GstBusHandler -> GstBusFunc, return value has the same meaning as any other GSource (FALSE == remove source). _add_watch() and _add_watch_full() now take a MessageType mask to only handle specific types of messages. _poll() returns the GstMessage instead of the message type to avoid race conditions. _have_pending() takes a MessageType mask now too. Added testsuite for multiple bus watches. Fix testsuites and applications for new bus API.
