8bca292c30 avcodec: Implement mpeg1 nvdec hwaccel
Once I remembered that there's a separate decoder type for mpeg1,
even though params struct is shared with mpeg2, everything worked.

4c7b023d56 avcodec: Refactor common nvdec hwaccel logic
The 'simple' hwaccels (not h.264 and hevc) all use the same bitstream
management and reference lookup logic so let's refactor all that into
common functions.

I verified that casting a signed int -1 to unsigned char produces 255
according to the C language specification.

This is mostly straight-forward. The weird part is that it should
just work for mpeg1, but I see corruption in my test cases, so I'm
going to try and fix that separately.
