Since RV40 and VC-1 use almost the same algorithm so optimizations for
those two decoders are easy to do and included.

NEON and VFP are currently mandatory for all ARMv8 profiles. Both are
handled as extensions as far as cpuflags are concerned. This is
consistent with handling x86_64 which always has SSE2, but still
handles it as an extension.

It could probably also be considered an error if the pointer isn't
null at this point, but then we might risk rejecting some
slightly broken files that we might have handled so far.

These arrays are normally freed at the end of mov_read_trak,
but make sure they're freed in case mov_read_trak returned
early (due to errors) or in case the atoms that allocate arrays
are encountered at some other point than within a trak (which
we don't have checks against).

Such files have IndexTableSegments which when parsed cover EditUnit
ranges like this:

 [0,1)
 [249,250)
 [249,377)
 [0,249)

where each interval is

 [IndexStartPosition, IndexStartPosition + IndexDuration)

This would be reduced to a sparse index like:

 [0,1), [249,250)

instead of the full range:

 [0,249), [249,377)

av_reallocp_array does the check already.

Without this fix the last sample was missing from the packet.

Overly large files are to be expected.

Always use the actually read size as the offset instead of making

The Omnia A/XE encoder writes the explicit extra data incorrectly
and wrongly disables parametric stereo. Truncating the extra data
by setting the size to 2 works around this. The AAC extra data
parser will then only parse the correct parts.

The global header is not explicitly required for playback, and
omitting it allows for simple concatenation.
