Prevents the decoder from being out-of-sync on an invalid packet. Also
returns OPUS_INVALID_PACKET on a corrupted FEC packet.

The previous version simply produced zeros for fixed-point.

This script updates version.mk, which is under version control,
so the tree is always dirty. Until the script is updated to write
package_version instead, incorporating version.mk as a fallback
the way update_version does, it's better not to use --dirty.

This generates a useful version string even for --depth=1 checkouts.
The option was added in git v1.6.6.

Default complexity is now 9.

Should fix delayed decision on surround, but not well tested.

We're now a bit more conservative and only take into account the bands
that are being codec. Also weighting the rate saving by the band width.

Not well tested.

Still untested.

This should make the scaling the same for fixed and float. It changes the float
scaling too by normalizing by the number of channels, which matters for
bandwidth detection.

Code is still float, but at least tonality esitmation seems to work.
Speech/music analysis is still disabled.

I checked that it's not *completely* busted, but it probably needs more testing.

The channel energy is now computed using an MDCT in the multi-stream
encoder rather than computing the energy of the stereo downmix.

Saves 2.5% on ARM without any asm. The float build still uses the old
code because celt_fir() then becomes a float function.

bit-exact with original version

Should gives us ARM/SSE optimizations for free.

Koen Vos for reporting the issue.

Thanks to thinqa for the report.
Fixes #1968.
