91b6ba653e Revert "avcodec/h2645: allocate film grain metadata dynamically" 
AVFilmGrainAFGS1Params, the offending struct, is using sizeof(AVFilmGrainParams)
when it should not. This change also forgot to make the necessary changes to the
frame threading sync code.
Both of these will be fixed by the following commit.

H274FilmGrainDatabase will be handled later.

This reverts commit 08b1bffa49.

c49001e338 avcodec/cbs_h266: Fix regression in DVB clip introduced by 93281630a7 
This commit introduced a regression to VVC_HDR_UHDTV1_OpenGOP_3840x2160_50fps_HLG10_mosaic.ts.

Root Cause:
The AV_CEIL_RSHIFT(a, b) macro uses bit tricks that work only when -a is a negative value.
However, due to integer promotion rules, this behavior does not extend to the unsigned int type.

See "6.3.1.1 Boolean, characters, and integers" in the "ISO/IEC 9899" for details.

2e338152a2 avformat/mov: use an array of pointers for heif_item 
Pointers to specific entries in the array are stored in other structs, so
in the scenario where heif_item was reallocated when parsing an iloc box after
and iinf one, the pointers may end up referencing freed memory.

Fixes use-after-free with such samples.
