Denny Sheirer f0db2865f2 #1397 Resolves issue where decoding channels go IDLE after period of time. Isolated the cause to a multi-threading issue where the polyphase channel manager receives notification that the tuner center frequency has changed and sets a flag to update each of the channels. This happens concurrent with a previous tuner center frequency change where the flag gets set and the second thread is updating the output processors with the previous frequency change and then unsets the frequency change flag, completely missing the second/latest frequency change update and causing the channels to all tune-out their desired signals as the tuner center frequency changes and the output channels continue mixing to the previous frequency. (#1407 )

Identified and resolved issue where a 2-stream polyphase synthesizer was being updated with an incorrectly designed synthesis filter which was causing massive droop on the second half of the reconstructed channel.  Oddly enough, this didn't seem to impact the P25 decoders, but it may have impacted other decoding.

Identified and resolved issue with concurrent modification of the modules list in the processing chain associated with recent addition of the channel FFT view in the channel power tab.
