to simplify future refactoring and development. In more detail: 1) Moved the updating of eBuf from the EchoSubtraction method to the EchoSuppression method as it is only used in the latter. 2) Moved the computation of efw and dfw from the SubbandCoherence method as those are actually the analysis filterbank computation that is not directly related to the coherence. 3) As a consequence of 2) 3 functions needed to be replaced by the generic function pointer scheme used in WebRTCAec as they have optimized versions for SSE2 and NEON (which before were local to each of the aec_core*.c files. Motivation: Apart from making sense from a logical point of view, the changes will a) Allow eBuf stored in half the size on the state. b) Allow simpler switching between using the the microphone signal and echo subtractor output in the echo suppressor. c) Allow further refactoring that move all the changes to eBuf to one method (currently those are happening in at least 4 different methods. Drawbacks: i) dfw is moved to EchoSuppression which increases the stack usage for that method. This will, however, be improved once further refactoring can be done. The changes have been tested for bitexactness on Linux using a quite extensive dataset.
