30e6effff9 avcodec/nvdec: add 4:2:2 decoding and 10-bit support
This commit adds support for 4:2:2 decoding for HEVC and H.264 on
NVIDIA Blackwell GPUs. Additionally, it supports 10-bit decoding
for H.264 on Blackwell GPUs.

790f793844 avutil/common: Don't auto-include mem.h
There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.

Keep it for external users in order to not cause breakages.

Also improve the other headers a bit while just at it.

7f92014aca avcodec/nvdec: don't free NVDECContext->bitstream
Ensure all hwaccels that allocate a buffer use NVDECContext->bitstream_internal
instead. Otherwise, if FFHWAccel->end_frame() isn't called before
FFHWAccel->uninit(), an attempt to free a stale pointer to memory not owned by
the hwaccel could take place.

e35dfe864d avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccel
This commit is the AVHWAccel analogue of commit
20f9727018: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

83c7ac2e47 avcodec/nvdec: Explicitly mark codecs that support 444 output formats
With the introduction of HEVC 444 support, we technically have two
codecs that can handle 444 - HEVC and MJPEG. In the case of MJPEG,
it can decode, but can only output one of the semi-planar formats.

That means we need additional logic to decide whether to use a
444 output format or not.

0e00624389 h264dec: add a NVDEC hwaccel
Some parts of the code are based on a patch by
Timo Rothenpieler <timo@rothenpieler.org>

Merges Libav commit b9129ec466.

Due to the name clash with our cuvid decoder, rename it to nvdec.

This commit also changes the Libav code to dynamic loading of the
cuda/cuvid libraries.
