e668fa2b5d Increase demodulator stack size on OSX 
Using pthreads as a drop-in, should work since underlying is already
pthreads?

746eca8d3e Demod worker now handles filter reconstruction 
Reduces audio jittering and only generates the last queued filter to
save redundant regeneration during dragging.

023002f009 Can now drag and resize demodulator on waterfall 
Pretty typical style of center = drag frequency, edge handles =
bandwidth

iirfilt_crcf_create_dc_blocker to reduce DC offset in IQ stream.

1554348f55 Demodulator can now tune offset! 
Demodulator will up-convert / down-convert by mixing VCO with incoming
IQ to shift frequency -- No longer limited to center freq. can listen
anywhere on the waterfall.

ddbc08a4ff Drag up/down to set arbitrary FM demod bandwidth 
Shouldn't need separate WBFM/FM/NFM setting this way -- Just "FM" and
then set arbitrary bandwidth by dragging.

Also removed redundant demod resampling stages left over from early
experiments.

99aa87df63 Now working on gcc4.8, x86-64 on windows 
Had to make my own portaudio and rtl-sdr binaries. The available
packages weren't compatible somehow.  Also wxWidgets wxPack doesn't
include OpenGL support but it's easy enough to compile.

6624ec11a3 IQ->Demod->Audio threads now chained 
No longer passing anything through the main thread which was causing
audio and IQ interrupts on UI events -- hopefully improves OSX jitter.

SDRThread can now have unlimited Demodulator bindings.. :)
