Some of the license wording was less than clear. Try to clarify the
different GPL 'downgrade' scenarios but also be generic to ensure that
those packagers where GPL is a problem check thoroughly before they ship.
Inspired by comments from Brian Cameron @ Oracle via fdo#41822
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).
* add GPL text
