Modified the JACK sink heavily:
* Made the sink realtime-safe.
* To achieve the previous item, internal buffering was be added. New module
argument: buffersize.
* Removed the user's need to set the JACK transport to playing state before he
could hear anything from PulseAudio.
* In process of achieving the previous item, latency calculation got more
inaccurate: the reported latency is now always a multiple of the JACK
processing block size, and constant.
* The JACK ports now have a running numbering in their names.
