sink-input: add a new API pa_sink_input_set_preferred_sink

Browse source 
If the sink here is NULL, that means users want to clear the
preferred_sink and move the sink-input to the default_sink, otherwise
set the preferred_sink to the sink->name and move the sink-input to
the sink. After that fire the sink_input_change event.

After adding this API, we can use this API to simplify the entry_apply
in the module-stream-restore.c.
