licensing changes
-----------------
Previously both libswscale and our AC-3 decoder had GPLed parts. These have
been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
but the C code is fully functional. Optimizations for other architectures have
been relicensed to LGPL.
AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
software OpenCORE libraries as an alternative to the non-free libamr libraries.
We found out that libfaac contains non-free parts and is not LGPL as previously
claimed. We have changed configure to reflect this. You now have to pass the
--enable-nonfree option if you wish to compile with libfaac support enabled.
Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
well that they were only used in a test program and never compiled into any
FFmpeg library.
