Refactoring of the noise suppressor and adding true multichannel support

Browse Source 
This CL adds proper multichannel support to the noise suppressor.
To accomplish that in a safe way, a full refactoring of the noise
suppressor code has been done.

Due to floating point precision, the changes made are not entirely
bitexact. They are, however, very close to being bitexact.

As a safety measure, the former noise suppressor code is preserved
and a kill-switch is added to allow revering to the legacy noise
suppressor in case issues arise.
