mov: Rework the check for invalid indexes in stsc
This commit is a noop, see 3c058f5701.
The proposed fix breaks seeking in multiple_stsd.mp4 (ticket #3962) and
playback of wwwq_cut.mp4 (ticket #2991).

Certain alpha run lengths (for SHQ1/SHQ3/SHQ5) could be stored in
both long and short versions, and we would only accept the short version,
returning -1 (invalid code) for the others. This could cause an
out-of-bounds write on malicious input, as discovered by
Andreas Cadhalpun during fuzzing.
Fix by simply allowing both versions, leaving no invalid codes
in the alpha VLC.

Multichannel joint stereo simply interleaves stereo pairs (6ch: 2ch + 2ch + 2ch), so each pair is decoded separatedly.
***
To test my changes, I converted examples to wav with ffmpeg.exe (old and new), and compared them to see they are byte-exact.
Regular 2ch files (JS and normal) were straightforward to test.
For multichannel, to check each JS pair is correctly decoded separatedly I did:
- manually demux 6ch.msf into 3 pairs and convert them (2ch_1.wav + 2ch_2.wav + 2ch_3.wav)
- convert the 6ch.msf file to wav (with my changes)
- manually demux the 6ch.wav into 3 pairs (6ch_d1.wav + 6ch_d2.wav + 6ch_d3.wav)
- compare each pair (ex. 2ch_3.wav vs 6ch_d3.wav): all pairs are byte-exact.
The new code just processes each JS pair separatedly, there are no algorithm changes.
It could be improved a bit but I'm not sure about typical styles.
I've only seen 6ch .MSF (probably the AT3 spec only supports 2ch audio).

return -1 is used here as it is used in similar code in this function, I intend
to replace it by proper error codes in the whole function.

mov: Wrap stsc index and count compare in a separate function
The mov_stsc_index_valid() function is replaced with a macro to prevent
signdness issues (index is not always signed, and count is always
unsigned currently).
The comparison is also adjusted to reduce the risk of overflows.

Retain the ranges of frame indexes when applying edit list in
mov_fix_index. The index ranges are then used to keep track of the frame
index of the current sample. In case of a discontinuity in frame indexes
due to edit, update the auxiliary info position accordingly.
