Arun Raghavan 14e784f9fc pulsesink: Add a getcaps function
This allows us to have more fine-tuned caps in READY or above. However,
this is _really_ inefficient since we create a new stream and query sink
for every getcaps in READY, which on a simple gst-launch line happens
about 35 times. The next step is to cache getcaps results.
