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.
