According to http://doc.iridas.com/index.php?title=LUT_Formats

    for 3D textures, the data is also RGB, and ordered in such a way
    that the red coordinate changes fastest, then the green coordinate,
    and finally, the blue coordinate changes slowest:

Some older compilers might have particular trouble with them,

This is a more sensible place for these macros.

Simplify/extend syntax.

The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.

INT_MAX is used here to denote the max allowed value for a pixel format.

The opt-test code is changed to provide a valid reference example.

Fix crash.

Address trac ticket #2868.

The eval mode allows to evaluate the expression per-frame or just at
init.

In particular, address ticket #3234.

The generic version should be faster if optimized.

Currently the min and max values are not honored, but this will change in
a following patch.

Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.

All scheduled API changes are deferred to the next bump.
