This can overread (either before start or beyond end) of the buffer in
Nx1 (i.e. height=1) images.

Fixes mozilla bug 1240080.

Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in
lavc/qtrle. To reiterate, 1-bit video is not necessary black & white in
QuickTime, merely bi-level. The two colors can be any color. The palette,
either included in the sample description, or the default Macintosh
palette (black & white for 1-bit video) will be set in lavf/qtpalette.
See the QuickTime File Format Specification for details.

Fixes compilation with --disable-fft.

It seems the previous tables where calculated with 32bit integers ignoring
overflows.
Also check for the max qindex, the value is choosen so that the qfactor/offset
fit in int32.

No longer needed since previous commit

TNS was computing filter coefficients incorrectly for short windows
due to a few coefficient addressing bugs. Fixing them fixes lots of
instability with transients (short windows).

I/S energy, especially when it comes to phase cancellations,
needs to use signed coefficients as input, yet it was using
abs'd coefficients. That was a slight bug.

Make sure to properly enforce maximum scalefactor delta in PNS
and I/S, not as an absolute range but relative to the previous
and first scalefactor, the latter important since PNS uses an
implicit inicial scalefactor derived from the global gain, and
encoded in a different way, which makes a big difference in the
allowed range.

The sample factor must be the same for both 8- and 10-bit functions chosen
otherwise the output will be incorrect.

Around 25% faster than the ssse3 version.

Around 35% faster than the avx version.
