- Fix moving of sink inputs between sinks

Browse source 
- Don't write more than a single buffer size in the ALSA driver at a time, to give the clients time to fill up the memblockq again
- Add API for querying the requested latency of a sink input/source output
- Drop get_letancy() from vtable of sinks/sources
