It's been deprecated for decades and in Debian system it's starting
to print warnings. Just use grep -F instead.

Add dummy typedef to avoid the warning

Added OPUS_SET_INBAND_FEC(2) since previous version

This makes kiss_twiddle_cpx 4-byte aligned (instead of 2-byte) for
fixed-point builds. Tested with an armv6j+nofp development board, CELT
encoding becomes 1.4x as fast, and decoding over 2x.

Performance gain is mostly attributed to the proper alignment of the
static const array mdct_twiddles960.

Not sure if it was the original intent, but we now reduce the
loss percentage threshold for pitch scaling as 1/nFramesPerPacket
since only the first frame will have pitch scaling anyway.
As a side effect, this brings back the original behavior of
disabling pitch scaling for 0% loss.

Reduces fluctuations in the non-FEC target bitrate.

Making LTP scaling depend on the bitrate and whether FEC is on.
The thresholds for scaling 1 and 2 are now independent.
