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.

This commit is the AVHWAccel analogue of commit
20f972701806be20a77f808db332d9489343bb78: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

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.
Some parts of the code are based on a patch by
Timo Rothenpieler <timo@rothenpieler.org>
Merges Libav commit b9129ec4668c511e0a79e25c6f25d748cee172c9.
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.
