Implements a complex sample delay buffer integrated into the tuner

channel manager so that channel source requests can have a start
timestamp specified and the channel can be preloaded with samples from
the delay buffer.  If no timestamp is specified, current time is assumed.

This feature requires corresponding updates to any decoder that wishes
to implement the timestamped sample preloading functionality.
