Description:
RNNoise is a noise suppression library based on a recurrent neural network.
The library is used for speech processing in WebRTC.

Local Modifications:
* Only retaining COPYING and from src/ the following files:
 - kiss_fft.c, kiss_fft.h
 - rnn.c
 - rnn_data.c
 - tansig_table.h
* KissFFT: non-floating point parts removed, code clean, from C to C++,
  class wrapper added
* BUILD targets and KissFFT unit tests added
* rnn_vad_weights.h: output layer sizes + weights scaling factor
* removing unwanted extern from constants in rnn_vad_weights.h and using
  constants to declare array sizes
* Add braces around arrays in unit test.
