Reference the AVFrame while the backing DMA-BUFs are used for scanout
...
This prevents tearing and other artifacts caused by the decoder
writing to a DMA-BUF that is currently being displayed.

Check modifiers support in IN_FORMATS property
...
As it turns out, there *are* in fact hardware vendors dumb enough
to ship V4L2 decoders that output buffers which are unsupported by
any plane on their display hardware. By checking modifiers, we can
still fall back to GLES on GL_IS_SLOW=1 builds in this case.

Remove async and non-blocking page flip support
...
It doesn't work well in practice for a few major reasons:
- It can result in the decoder writing on DMA-BUFs being used by the display
- It can generate page flip events that collide with Qt/SDL
- It can stall the decoder if the DMA-BUF has a fence on it from the display driver

Handle missing bitstream restrictions element in H.264 SPS fixup
...
NVENC on the 591.59 driver seems to not include the bitstream
restrictions element, which renders our attempt to set the
max_dec_frame_buffering value ineffective. Handle this by
providing inserting default bitstream restrictions if one
is not present.
