Added FrequencyOfInterestControlMessage support to allow radio models to set
their frequencies of interest. Control message valid as part of
processDownstreamControl and processDownstreamPacket. Control message will cause
the spectrum monitor to flush any preexisting spectrum information.

Added FrequencyOfInterestControlMessage support to phyupstreamscenario test harness.

Removed FrameworkPHY::foi_ class member and replaced with a local variable in configure()
Added missing test case input XML to makefile for inclusion in source dist
Removed bandwidth test as a conditional for resetting the transmitter bandwidth
cache. Cache has NoiseRecorder references and must be cleared every time the
SpectrumMonitor is reinitialized.
Added phyupstreamscenario005 test case for FrequencyOfInterestControlMessage
Merge branch 'feature/foicontrolmessage' into develop
