I don't think we should support interlacing in the netvc bitstream. I
bring this up because draft-filippov-netvc-requirements-01 still
specifies some interlaced modes.

Arguments against interlacing:
- Requires extra features to encode efficiently. HEVC has dropped MBAFF,
libvpx has never supported interlacing.
- Moves deinterlacer complexity to the encoder, which is an easier place
to offload complexity
- There are no internet-connected interlaced displays in common usage

If anyone has counterarguments, I'd like to hear them.
