sink: Introduce structure needed to consolidate virtual sink code

Browse source 
This patch introduces the vsink structure which holds all data needed
by virtual sinks. This is in preparation of the consolidation of the
virtual sink code. The input_to_master field of the sink will be moved
to the vsink structure after the consolidation. Until all virtual sinks
are converted, sink->input_to_master and sink->vsink->input_to_master
must both be supported.
