Commit cd483180 added support for NV24 and NV42, including several
fate tests for these formats, but did not include the reference files
for the tests filter-pixdesc-nv24 and filter-pixdesc-nv42. As a result,
these two tests were broken.

Some formats use longer names than 12.
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

In libswcale/tests/swcale.c, the function fileTest() calls sscanf in
an argument of "%12s" on character srcStr[] and dstStr[], which are
only 12 bytes.  So, if the input string is 12 characters, a
terminating null byte can be written past the end of these arrays.

This bug was found by cppcheck.

Prevents crash or interruption in text rendering
if new option string contains invalid values.

Hardware-accelerated encoding may not support 10-bit encoding. Use
'-require_sw 1' in this case.

Lauri had asked me what the semi planar formats were and that reminded
me that we could add it to pixdesc_query so we know exactly what the
list is.

The implementation is pretty straight-forward. Most of the existing
NV12 codepaths work regardless of subsampling and are re-used as is.
Where necessary I wrote the slightly different NV24 versions.

Finally, the one thing that confused me for a long time was the
asm specific x86 path that did an explicit exclusion check for NV12.
I replaced that with a semi-planar check and also updated the
equivalent PPC code, which Lauri kindly checked.

These are the 4:4:4 variants of the semi-planar NV12/NV21 formats.

These formats are not used much, so we've never had a reason to add
them until now. VDPAU recently added support HEVC 4:4:4 content
and when you use the OpenGL interop, the returned surfaces are in
NV24 format, so we need the pixel format for media players, even
if there's no direct use within ffmpeg.

Separately, there are apparently webcams that use NV24, but I've
never seen one.

perfer avctx->framerate first than use avctx->time_base when setting
