Clarify and add examples for the behaviour of the quantisation offset,
and define how multiple ranges should be handled.

Monochrome 10 and Main 10 Still Picture profiles are added by the 2018
version of the standard.

Operates in the same way as the h264-levels test.

To match the same option in h264_metadata.

The maxDpbPicBuf value which is used in the DPB size calculation depends
on the profile (it's usually 6, but 7 for screen-extended profiles).

This commit fixes an overflow introduced in a569a7b3 that affected EBML
elements that the Matroska demuxer doesn't want to parse like CRC-32
elements. The return value of avio_skip (the new position on success or
an AVERROR on failure) has been assigned to an integer which meant that
new positions in the range of 2GB to 4GB-1 etc. were considered errors.

Fixes ticket #8001.

The linearize function (usually refered to EOTF) is the inverse of
delinearize function (usually referred to OETF). Demarcation point of
EOTF should be beta*delta, but the actual value used now in the source
code is beta.

For ITU Rec.709, they are 0.081 (0.018*4.5) and 0.018 respectively
(beta = 0.018 and delta = 4.5), and they correspond to pixel value 5
and 21 for an 8-bit image. Linearized result of pixel within that range
(5-21) will be different, but this commit will make linearize function
of the filter more accurate in the mathematical sense.
