5481fb7d4d 61 Rotating Control Channel Support - P25 Decoder (#475)
* Initial work on add support for rotating control channels.

* Creates multiple frequency editor control.

* Updates channel source editor to allow user to select multi-frequency
configuration and add multiple frequencies.

* Adds full support for rotating control channels to the P25 channelizer.
Users define multiple frequencies in the channel source configuration.
The decoder monitors the state of the channel for a CONTROL state.  If
the state does not stay in the CONTROL state for a user-specified delay
value, then the decoder rotates to the next frequency in the list.  This
behavior continues until the decoder state once again changes to CONTROL.

This is NOT a 'scanner' feature.

609a1e86c7 Resolves #364.
The C4FM and LSM decoders were issuing a PLL reset with each new
channel that was allocated, causing any existing decoding channels to
be disrupted.  Decoding re-sync delays or inability to recapture the
 signal for decoding would likely result as the tuner's overall PPM
 caused misadjustment in the channel.

Resolved a NPE that was occurring in the FrequencyController for
sample rate changes.

104c4f72be Resolves #170 adding support for Airspy Mini tuner's 3 and 6 MHz
sample rates.

Resolves issue in PolyphaseChannelManager responding to sample rate
changes in the tuner.  The manager now recreates the channelizer when
needed if the tuner's sample rate has changed since the last time the
channelizer was used.

Updates the Tuner selection view to reflect tuner lock state.  Updates
the tuner editors to enable/disable frequency controller and sample
rate controls according to the tuner's lock state.

6f1ce79461 [WIP] Updates the AM decoder module.
Removes a number of unused classes in an effort to remove RealBuffer
usage across the codebase (has been replaced by ReusableBuffers).

96d9d6f750 [WIP] Adds locking mechanism to tuner controllers so that the
polyphase channel manager can block users from changing frequency and/or
sample rate when polyphase channels are allocated.
