sys/sunaudio/: Use the sunaudio debug category.

Original commit message from CVS:
* sys/sunaudio/gstsunaudiomixerctrl.c:
* sys/sunaudio/gstsunaudiosrc.c:
Use the sunaudio debug category.
* sys/sunaudio/gstsunaudiosink.c: (gst_sunaudiosink_finalize),
(gst_sunaudiosink_class_init), (gst_sunaudiosink_init),
(gst_sunaudiosink_set_property), (gst_sunaudiosink_get_property),
(gst_sunaudiosink_open), (gst_sunaudiosink_close),
(gst_sunaudiosink_prepare), (gst_sunaudio_sink_do_delay),
(gst_sunaudiosink_write), (gst_sunaudiosink_delay),
(gst_sunaudiosink_reset):
* sys/sunaudio/gstsunaudiosink.h:
Uses the sunaudio debug category for all debug output
Implements the _delay() callback to synchronise video playback better
Change the segtotal and segsize values back to the parent class
defaults (taken from buffer_time and latency_times of 200ms and 10ms
respectively)
Measure the samples written to the device vs. played.
Keep track of segments in the device by writing empty eof frames, and
sleep using a GCond when we get too far ahead and risk overrunning the
sink's ringbuffer.
Fixes: #360673
