hevcdsp_template: Templatize IDCT
This commit is a noop as we already have that code from a previous
commits (see 92cccb7bcd).
Spacing is adjusted to reduce the diff.

hevc: Separate adding residual to prediction from IDCT
This commit should be a noop but isn't because of the following renames:
- transform_add → add_residual
- transform_skip → dequant
- idct_4x4_luma → transform_4x4_luma

Allows the user to reserve space for the ODML master index. A sufficient
sized master index in the AVI header avoids storing follow-up master
indexes within the 'movi' data later. If the option is omitted or zero
the index size is estimated from output duration and bitrate.

The current implementation creates new segments comparing
pkt->pts - first_pts > nb_segs * min_seg_duration
This works fine, but if the keyframe interval is smaller than "min_seg_duration"
segments shorter than the minimum segment duration are created.
Example: keyint=50, min_seg_duration=3000000
segment 1 contains keyframe 1 (duration=2s < total_duration=3s)
and keyframe 2 (duration=4s >= total_duration=3s)
segment 2 contains keyframe 3 (duration=6s >= total_duration=6s)
segment 3 contains keyframe 4 (duration=8s < total_duration=9s)
and keyframe 5 (duration=10s >= total_duration=9s)
...
Segment 2 is only 2s long, shorter than min_seg_duration = 3s.
To fix this, new segments are created based on the actual written duration.
Otherwise the option name "min_seg_duration" is misleading.

Codec 4 (frame size 98) uses joint stereo per spec and examples.
Also removed an incorrect "align" var which wasn't used anyway (it was overwrittern).
Probably all/only .AT3 of frame size 98 are JS, too.

Place all temporary files within a single, quasi-atomically created
temporary directory rather than relying on unsafe 'mktemp -u'. This
prevents possible race conditions in case two parallel 'mktemp -u' calls
returned the same path. Additionally, it reduces TMPDIR pollution by
keeping all test files in a single subdirectory.

Instead of just updating statistics and leaving the work to the
call site, have it actually do the work.
Also: skip the samples by updating the frame data pointers
instead of moving the samples. More efficient and avoid writing
into shared frames.

Servers seem to be happy to receive the wrapped-around value as long
as they receive a report, otherwise they timeout.
Initially reported and analyzed by Thomas Bernhard.
Name and purpose are more appropriate there since the code isn't
an ideal example.

This allows testing EC and non EC. Avoids spending most time in EC on
high res samples and reduces the likelyhood of hitting timeouts
