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)

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.
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.
