All functions in this file can access the structure field of an event directly.
This avoids having to call gst_query_get_structure() to get it, along with being
able to remove some function variables that were used to store the result of that
function.
gst_event_new_sink_message()
gst_event_parse_sink_message()
This event is used for sending a GstMessage downstream and synchronized
with the stream, to be posted by the sink once it reaches the sink.
Fixes bug #602275.
Add new STEP event and methods for creating/parsing the event
Update design docs.
Add new STEP_DONE message and method to create/parse.
API: GstEvent::gst_event_new_step()
API: GstEvent::gst_event_parse_step()
API: GstMessage::gst_message_new_step_done()
API: GstMessage::gst_message_parse_step_done()
Use gst_structure_id_empty_new() in combination with GST_QUARK
rather than gst_structure_id_new() when creating message, event,
query and taglist structures. Mostly just because we can.
