Express bitfields more simply.

In these cases, there is no extradata but only the properly set
width/height values by the demuxer.

This makes sure VP6 in F4V files is cropped properly.

This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f515091.

This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

Returning 0 for failure is misleading.

Interlacing is not supported at all and mismanaged down the normal
codepaths causing possible buffer management issues.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers.  The new
function pointers enable optimised implementations of the filters.
