[opus] Opus is now RFC 6716, plus stable releases

[Jean-Marc Valin]

Hi everyone,

We finally made it! Opus is now standardized by the IETF as RFC 6716
(http://tools.ietf.org/html/rfc6716). See the announcements at:
https://hacks.mozilla.org/2012/09/its-opus-it-rocks-and-now-its-an-audio-codec-standard/
http://www.xiph.org/press/2012/rfc-6716/
Feel free to spread those around :-)

We're also releasing both 1.0.0 (same code as the RFC) and 1.0.1, which
is a minor update on that code (mainly with the build system). As usual,
you can get those from http://opus-codec.org/

Thanks to everyone who contributed by fixing bugs, reporting issues,
implementing Opus support, testing, advocating, ...

Enjoy!

	Jean-Marc
