proplist: Add internal API to get stream group

Browse source 
This moves out code from module-stream-restore and makes an internal API
out of it to get a "stream group" for a given sink input or source output.
This is factored out for reuse in module-filter-*.

The stream group basically provides some means of attaching a logical
identification to the stream (by role, application id, etc.).
