Where are those numbers coming from? From the spec? From an annex?
- quantizer delta and matrix level specific.
- support loop filter delta.
- support use superres.

For film grain clip, vaapi_av1 decoder will cache additional 8
surfaces that will be used to store frames which apply film grain.
So increase the pool size by plus 8 to avoid leak of surface.

Since order_hint_bits_minus_1 range is 0~7, cur_frame_hint can be
most 128. And similar return value for cbs_av1_get_relative_dist.
So if plus them and use int8_t for the result may lose its precision.

These are some cosmetic changes and also priming the decoder for sprite
support (which i plan on adding). This patch was mainly for me to get
used to the git email patch flow, if anything. Of course the decoder
still works as it was before (i tested it).

Allows shifting of subtitle display times to align them with the video.
This avoids having to rewrite the subtitle file in order to display
subtitles correctly when input is seeked (-ss).
Also handy for minor subtitle timing corrections without rewriting the
subtitles file.

The whole purpose of the params field was to give it off to the encoder
and have it do its own parsing, such that we wouldn't have to keep up
adding more and more options.
