echo-cancel: Add alternative echo-cancellation implementation
This adds Andre Adrian's AEC implementation from his intercom project (http://andreadrian.de/intercom/) as an alternative to the speex echo cancellation routines. Since the implementation was in C++ and not in the form of a library, I have converted the code to C and made a local copy of the implementation. The implementation actually works on floating point data, so we can tweak it to work with both integer and floating point samples (currently we just use S16LE).
