Ralph Giles 573c99e500 Bug 674225 - Add the opus draft-11 source to the tree. - r=derf 
This is the IETF Opus audio codec reference implementation.
The source was copied into the tree using the included
update.sh script, from a checkout of the v0.9.9 git tag,
which corresponds to the source code published in
https://tools.ietf.org/id/draft-ietf-codec-opus-11.txt
