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.

Add sequence numbers to events and messages. See #559250.
* gst/gstutils.c (gst_util_seqnum_next, gst_util_seqnum_compare):
New functions.
* gst/gstevent.h:
* gst/gstevent.c (_gst_event_copy, gst_event_new): Initialize new
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.
* gst/gstmessage.h:
* gst/gstmessage.c (_gst_message_copy, gst_message_new_custom):

* gst/gstmessage.h:
Implement STRUCTURE_CHANGED messages. These messages will be used to
signal the parent bin of link/unlink operations that could require a
resync when doing a state change. See ##510354.

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.

* gst/gstelement.h (GstState): Renamed from GstElementState,
changed to be a normal enum instead of flags.
(GstStateChangeReturn): Renamed from GstElementStateReturn, names
munged to be GST_STATE_CHANGE_*.
(GST_STATE_CHANGE): Renamed from GST_STATE_TRANSITION, updated to
work with the new state representation.
(GstStateChange): New enumeration of possible state transitions.
Replaces GST_STATE_FOO_TO_BAR with GST_STATE_CHANGE_FOO_TO_BAR.
(GstElementClass::change_state): Pass the GstStateChange along as
an argument. Helps language bindings, so they don't have to use
tricky lock-needing macros like GST_STATE_CHANGE ().
* scripts/update-states (file): New script. Run it on a file to
update it for state naming and API changes. Updates files in
place.
* All files updated for the new API.
