dad06a445f avcodec/Makefile: Remove h263 decoder->mpeg4videodec.o dependency 
Also prefer using #if CONFIG_MPEG4_DECODER checks in order not
to rely on DCE.

0035d99c61 configure: Avoid mpeg4video_parser->{h263,qpel}dsp dependency 
This can be easily achieved by moving code only used by the MPEG-4
decoder behind #if CONFIG_MPEG4_DECODER.

ad77345a5d avcodec/exif: add EXIF parser and struct API 
This commit adds a structure to contain parsed EXIF metadata, as well
as code to read and write that struct from/to binary EXIF buffers. Some
internal functions have been moved to exif_internal.h. Code to read
from this new struct and write to an AVDictionary **dict has been added
as well in order to preserve interoperability with existing callers.
The only codec changes so far as of this commit are to call these
interop functions, but in future commits there will be codec changes to
use the new parsing routines instead.

75aeffb1c6 lavc: add a ProRes RAW Vulkan hwaccel 
This commit adds a ProRes RAW hardware implementation written in Vulkan.
Both version 0 and version 1 streams are supported.
The implementation is highly parallelized, with 512 invocations dispatched
per every tile, with generally 4k tiles on a 5.8k stream.

Thanks to unlord for the 8-point iDCT.

Benchmark for a generic 5.8k RAW HQ file:
6900XT: 63fps
7900XTX: 84fps
6000 Ada: 120fps
Intel: 9fps

Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.
