TrueHD supports more channels than FFmpeg, so a valid sample
could set the channel layout to a value that represents less
channels than the sample actually consists of.

In particular, now it assumes that
a) chapters are chronologically ordered
b) chapters have the same timebases
c) duration of the stream is known
and asserts if any of these is not met.

Make it properly deal with harsher conditions.

To avoid further special-casing, dummy AVHWAccels are added
for VDPAU.
It should be possible to move VDPAU completely to AVHWAccel later.

Part of the fft8() function corresponds to the BUTTERFLIES macro,
so use it.

of data was not silent.

These expressions are equivalent since levels is always odd, and
overflow is impossible due to the constraints set by the assert().
