This fixes such usage.

GCC 3.4 introduced an attribute warn_unused_result to warn when a programmer
discards the return value. Applying this judiciously across the codebase can help
in fixing a lot of problems. At a high level, functions which return error codes
should always be checked. More concretely, consider the functions ff_add_format
and the like in avfilter/formats.h. A quick examination shows that a large portion
of libavfilter fails to handle the associated errors, usually AVERROR(ENOMEM).
The above example was where I observed the utility of this, but it should be
useful in many places across the code base.

These are DNxHR profiles with the following properties:
- Variable size in a profile (property added in a previous commit),
  requiring variable-sized macroblock table;
- Variable bitdepth, up to 12 bits.
- Better validation of buffer sizes and positions

This a 4:4:4 10 bits profile, where image size is not fixed by the
profile, and which strays a bit outside the old frame header parsing
code.

Fixes ticket #4581 (DNxHR is not stricly supported, but that sequence is).

Currently not used, but will be used to indicate that a CIDEntry field
is not set, because it is variable, and that checks should be adapted.

Move the 'interlaced' flag to this element (arbitrarily set to 16bits).
This should allow better detection/selection of profiles.
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

Rely more on the actual syntax from the specs (also seen in the
encoder code).
