Andy Wingo e44beb9f04 gst/elements/gstfakesink.c (gst_fakesink_render): Er, emit with
Original commit message from CVS:
2005-05-10  Andy Wingo  <wingo@pobox.com>

* gst/elements/gstfakesink.c (gst_fakesink_render): Er, emit with
*all* the arguments.

* gst/base/gstbasetransform.c (gst_base_transform_event): Grab the
stream lock if it's a FLUSH_DONE; normal flushes don't get the
lock (according to the docs -- if this is wrong change the docs).

* gst/gstpipeline.c (gst_pipeline_change_state): Set the bus to
flush messages in the NULL state.

* gst/gstbus.c (gst_bus_post): If a bus is flushing, unref the
message immediately and return.
(gst_bus_set_flushing): New function. If a bus is flushing, it
flushes out any queued messages and immediately unrefs new
messages. This is so when an element goes to NULL, all of the
unhandled messages coming from it can be freed, and their
references to the element dropped. In other words: message source
ref considered harmful :P

* gst/gstbin.c (gst_bin_change_state): Unref peer element when
we're finished with it.

* gst/gstmessage.c (gst_message_new_state_changed):
