New upstream release with only minor cleanup after 1.2-rc1.
- Speech quality improvements especially in the 12-24 kbit/s range
- Improved VBR encoding for hybrid mode
- More aggressive use of wider speech bandwidth, including fullband speech
starting at 14 kbit/s
- Music quality improvements in the 32-48 kb/s range
- More optimizations for x86 (SSEx) and ARM Neon
- Support for directly encoding packets up to 120 ms
- DTX support for CELT mode
- SILK CBR improvements
- Support for all of the fixes in draft-ietf-codec-opus-update-04 (the mono
downmix and the folding fixes need --enable-update-draft)
- Many bug fixes, including integer overflows discovered through fuzzing
(no security implications)

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.

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)
MozReview-Commit-ID: IcdnCok500X
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.
