* sys/sunaudio/gstsunaudiosrc.h:
Add a SunAudio source plugin.
Support stereo and right/left channel gain in the mixer plugin.
Support the RECORD flag so that you can switch between line-input and
microphone in gnome-volume-control.
Code cleanups like using an enumerator for track number instead of an
integer. Fixes #344923.
