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.

It caused a segfault when channel reordering was in use and the last chunk
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().

'keyframes' metatag is not part of the standard, it is just
convention to use such kind of metatag information for indexing.
Structure is following, it allows to have it inconsistent:
keyframes:
 times (array):
  time0 (num)
  time1 (num)
  time2 (num)
 filepositions (array)
  position0 (num)
  position1 (num)

A zero sized stsc run doesn't make a lot of sense but the spec does not
prohibit them and MPlayer VLC demuxers support them.
