AviSynth 2.6 (and by extension, AviSynth+) moves these functions
into AVSC_API. This requires both adjusting their normal use,
and for AvxSynth, adjusting the position/use of the USING_AVISYNTH
ifdefs.

Rename the existing tscc2 test.

This will allow to copy the matrix as is and it is just cleaner to keep
the matrix in the same order specified by the mov standard (which is
also explicitly described in the documentation).

In order to preserve compatibility, flip the angle sign in the display API
av_display_rotation_set() and av_display_rotation_get(), and improve the
documentation mentioning the rotation direction.

These are essential allowing QuickTime to keep detecting content
as slow-motion - this allows preserving them on stream copy.

While it is a per-frame variable, it is only really used in the
low-level decoding code, so it is more efficient to store it in the
slice context.

There is no need to store a whole H264Picture, with a full AVFrame
embedded in it. This should allow getting rid of the embedded AVFrame
later.

This code makes no sense for h.264.

There is now no need to have per-slice copies of the H264Context.

All the variables modified by this code are either per-MB arrays or have
been moved to the per-slice context
