#39 WIP - initial efforts to restructure the way tuners and tuner
57fab2b 
controllers manager sample buffer processing and channel management.
General cleanup across all modules to remove the executor from each
of the start() methods.  Removed the B100 tuner class since it's not
yet implemented.

#39 WIP - adds support for timestamped complex buffers so that decoded
05fa5c2 
messages and events can be accurately timestamped, and more importantly,
allocated traffic channels can request to be pre-loaded with buffered
samples to ensure that traffic channels don't miss any samples that
are currently missed due processing latency inherent in current buffer
sizing.  This should reduce the clipping of starting messages or voice
on the traffic channels.

Restructures processing path for tuner frequency and sample rate change
events.  The tuner now embeds these events in the sequence of buffers
that are generated immediately after the event occurs since those are
the buffers that will be impacted by the change.  Previously, the change
event would be broadcast throughout the system and would impact any
buffered/cached buffers.  This also reduces the number of source event
change listeners that have to be managed.  Note: this change is not yet
implemented in all tuners ... only in the TestTuner implementation.

Updates the polyphase channelizer to now buffer channel results and then
dispatch the buffer to the channel output processors to improve efficiency
of using float arrays versus single value complex float processing.

#39 WIP - rolls back embedding source events in buffers. The channel
d4761be 
calculator must be updated immediately any time the tuner's center
frequency changes so that a channel can be allocated immediately.  So,
I changed source event handling to two parts where the channel calculator
is immediately updated and the channelizer configuration is deferred so
that it can happen on the buffer processor execution thread and we can
avoid any sync() locking on the channelizer or polyphase channel
sources.
