* libs/gst/base/gstbasesink.c: (gst_base_sink_query_latency),
(gst_base_sink_event), (gst_base_sink_query),
(gst_base_sink_change_state):
Simplify latency query.
When not synchronizing, we can report latency without querying the peer
element.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_preroll_queue_flush),
(gst_base_sink_event), (gst_base_sink_change_state):
Sinks that don't preroll can always be queried for the latency.
Don't post ASYNC start when we are not async.

(gst_base_sink_change_state): Add a case for READY_TO_PAUSED after
chaining up, in which we return SUCCESS directly if we activated
in pull mode instead of ASYNC. Involves countering an async_start
message sent before chaining up; not sure if this is correct, in

Keep track of time in the queue by measuring the difference between
running_time on input and output. This gives more accurate results and
can compensate for segments correctly.
Make a queue by default only 5 buffers deep. We will now increase the
buffer size depending on the filledness of the other queues.
Factor out commong flush code.
Make sure we don't add additional refcounts to buffers when we can avoid
it.
Propagate GstFlowReturn differently.
Use GSlice for intermediate GstMultiQueueItems.
Keep track of EOS.
Resize queues on over and underruns based on filled level of other
queues.
When checking if the queue is filled, prefer to measure in time if we
can and fall back to bytes when no time is known.

API: gst_controller_suggest_next_sync(), gst_object_suggest_next_sync()
Add API that provides sync suggestion timestamps for elements that
call gst_object_sync_values() from which those elements can subdivide
their processing loop to get the best results for the controlled
properties. For now it just suggests last_sync + control_rate as
new timestamp but this will be improved in the future.
While doing that change the control-rate property to a GstClockTime
from guint and change it's meaning from samples to nanoseconds as
the GstController doesn't know anything about sampling rate. Strictly
speaking this breaks ABI but as the control-rate property didn't do
anything in the past and as such couldn't be used this should be no
problem.
