Update our in-tree implementation of the opus audio codec
to the 1.2 release candidiate. This gives us some wider
testing before making the first stable release of the
new series.
This release improves the quality and compactness of encoded
audio, and optimizes performance on ARM NEON platforms.

Our minimum-supported version of gcc is not 4.9, so we can
remove the work-around patch for the Internal Compiler Error
we encountered with the opus library and 4.8.

New upstream release.
This is a minor release focusing mainly on optimizations and bug fixes.
- Neon optimizations inproving performance on ARMv7 and ARMv8 by up to 15%
- Fixes some issues with 16-bit platforms (e.g. TI C55x)
- Fixes to comfort noise generation (CNG)
- Documenting that PLC packets can also be 2 bytes
- Includes experimental ambisonics work (--enable-ambisonics)

This release fixes two bugs:
- Resetting the encoder or decoder state with OPUS_RESET_STATE would
disable some run-time selected architecture-specific optimizations.
- In hybrid mode discontinuous transmission (DTX) operation, the
comfort noise above 8 kHz was incorrectly estimated and could
oscillate in time.
The androidabi-4.8 toolchain we'd liek to use for B2G ICS builds cannot
compile this section of the opus source. Force-disable optimizations
for the offending code in order to avoid the ICE.
Update our opus implementation to a prerelease of 1.1. This
brings many performance and encoder improvements and we believe
it is stable enough to switch. This import does not enable any
of the new assembly optimizations.
The imported code is https://git.xiph.org/opus.git master
commit f2446c25c6519bae190152f7a579310b83dc43fd.
Update files to match the opus-1.0.0 source release.
This corresponds to the spec implementation included
in RFC 6716.
Changes from the previous in-tree version (draft-12):
- Add extern "C" protection on opus_multistream.h.
- Align to sizeof(void*) instead of 4 bytes.
- Copyright header updates for IETF publication.
- Minor documentation and whitespace fixes.
Bug 716478 added MPL2 license headers to a couple of (headerless) files
in media/libopus. These files are third-party code and covered until the
associated BSD license of the upstream project.
Although the files in question are either source file listings, or
programmatically generated, and as such not copyrightable, labelling
them as MPL2 is technically incorrect.

Updates our copy of the libopus reference implementation to
match http://tools.ietf.org/html/draft-ietf-codec-opus-12
This uses the v0.9.10/draft-12 tag from the upstream git repo.
Summary of changes:
- License header updates
- Warning fixes
- Comment improvements
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
