bfaacb309d 39 - WIP - incorporates the latest P25 C4FM decoder from master and
updates the LSM decoder to follow the same design pattern.  Adds LSM
decoder support to the demodulator viewer application.  The current
symbol timing gain for LSM is set too high -- is using the C4FM gain
and causes too much fluctuation in the timing error.

030fc1617c 328 Channel Auto-Start capability. Adds auto-start and auto-start
ordering to each channel configuration to provide the user with greater
control over initial application startup configuration.

Adds new dialog window that displays on startup that allows the user to
invoke/cancel auto-start, or simply allow the timer to expire whereby
the channels will be auto-started.

Updates channel table model to include an auto-start column and relabels
the 'Enabled' column to read 'Playing'.

Updates channel editor to change the 'Enable/Disable' button to read
'Start/Stop'.

Changes the 'enabled' property of the channel configuration to indicate
the current 'processing' status - isProcessing().

Channel's XML configuration re-purposes the 'enabled' property to indicate
auto-start and adds a new (optional) auto-start 'order' attribute.

f2f2c92afe [WIP] Implements reusable sample buffers across all components. This
produces a significant reduction in memory usage, especially for tuners
like the airspy and hackrf that produce 10/20 MSPS sample rates.  This
is observed to be around 66% reduction in peak memory usage and provides
a more stable memory utilization across time reducing stress on the
garbage collector.

Use of these reusable memory buffers will be pushed further down into
the processing chain modules to ensure we keep new object creation
to the lowest levels possible.

32ab0598e8 Updates sample generator and test tuner controller to support multiple
complex buffer listeners.  Removes complex buffer broadcast support from
the source manager and renames it to channel source manager to convey
that it's only responsible for providing channels from the tuner.

d5b377b1af Resolves #318. Redesigns DFT processor to use a non-blocking queue approach to
access incoming buffer streams coupled with a overflowable queue that
limits the quantity of complex buffers that are cached for the DFT
processor.
