This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.

Various cleanups.
Added methods to get the current levels and to inform the queue that the
'full' limits changed.

(gst_single_queue_new):
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.
* plugins/elements/gstqueue.c:
Fix return value.

Fix multiqueue leaking buffers and events when downstream or the
queue are flushing. Make refcounting assumptions explicit and
document them (shouldn't break existing code that uses it other than
maybe leak miniobjects, but that already happens anyway). Add unit
test for the most common flushing case. Fixes#423700.
