EVO-PLAYER (PPSA99039) creates resident AVC, HEVC and VP9 decoders at
start-up, and stopped at "Videodec2: unsupported codec" on the HEVC one.
Codec types 974921 (HEVC) and 2382845 (VP9) now open FFmpeg's HEVC and
VP9 decoders. HEVC input goes through the same Annex B conversion as
H.264 and VP9 frames are passed through; output stays 8-bit NV12, and a
frame deeper than 8 bits throws. Picture info throws for HEVC and VP9,
whose layouts differ from the AVC one.

Adds libSceVideodec2. Access units (Annex B, or length-prefixed rewritten to
Annex B) are decoded by FFmpeg's H.264 decoder into the title's NV12 frame
buffers (256-byte pitch, chroma after the visible luma rows). Decode hands
out at most one picture per call, Flush drains the reordered ones, Reset
clears the decoder; timestamps and attached data travel with the picture.
FFmpeg is found through pkg-config and is optional: without it the decoders
return black pictures. guest_videodec2_tests checks the pictures of an
embedded stream against reference hashes.
