Simply use casting macros for accessing the message fields like we do for
buffers and events. Avoids some costly typechecking that does not really buy us
much.
Update design doc with step-start docs.
Add eos field to step done message
when stepping in reverse, update the segment time field.
Flush out the current step when we are flushing.
Update framestep document, we want to pass the flush flag in the step-done
message.
Add flush flag to the gstmessage.
Update examples to use the new step-done message api.
Implement framestep with playback rates < 0.0 too.
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()

unref and copy functions are sometimes used as function
pointers for example in the case of g_hash_table_new_full
as a GDestroyNotify function.
Currently GstBuffer, GstEvent, GstMessage and GstQuery
define their respective unref and copy functions as
macros, making use of gst_mini_object_unref/copy.
This approach works very well for most cases, except
for some automatically generated bindings (currently Vala),
where the memory management semantics are defined
declaratively.
The possible solutions would be to either convert all
the macros into static inline function, or change the
signature of gst_mini_object_unref to take a void*
instead of a GstMiniObject*.
Fixes bug #572480.
Add a GST_MESSAGE_REQUEST_STATE that can be posted by element when they would
like to have the application change the state of the pipeline. the primary use
case is to pause the pipeline when an audio mixer is mixing a higher priority
stream but it can also be used for other purposes.
Add some docs and a unit test.
Implement the REQUEST_STATE message in gst-launch.

events with a new sequence number, and copy it when copying.
(gst_event_get_seqnum, gst_event_set_seqnum): Accessors for an
event's sequence number.

Make gtk-doc generate docs for our inlined gst_buffer_ref(),

Seriously, this is better than a previous commit as we only need
to notify the fact that an element changed state in a streaming
thread, marking the state of the parents dirty, hence the
STATE_DIRTY message instead of abusing a boolean in a STATE_CHANGE
message.
