Partially revert "avformat/matroskadec: set aspect ratio only when DisplayWidth and DisplayHeight are in pixels"

The code works just fine regardless of unit, so only make sure DisplayUnit
is not "unknown".

It's container level information on some formats (Matroska, MXF, yuv4mpeg), so
it should be printed at higher log levels than debug.

We don't currently support values 1 (centimeters), 2 (inches) or 3 (DAR),
only the default value 0 (pixels) which doesn't need to be written.

The fate refs are updated as unknown SAR is now signaled in the output
files with the addition of the new element.

A missing DisplayUnit element or one with the default value of 0 means
DisplayWidth and DisplayHeight should be interpreted as pixels.

The current code setting st->sample_aspect_ratio is wrong when DisplayUnit
is anything else.

The calculation of width/height should round up, not round down to
prevent setting width or height to 0.

Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
calculation could silently wrap around without the explicit cast to int.

This is a similar filter to f_metadata, only it works on side data. Since
adding side data from a user provided arbitrary binary string is unsafe,
because current code assumes that a side data of a certain kind has the proper
size, this filter only implements selection and deletion. Also, no value
matching support is implemented yet, because there is no uniform way to specify
a side data textually.

Use check_lib2 to test the header together with the function. This is
necessary, because '-DOPJ_STATIC' changes what the included header does.

Also add '-DOPJ_STATIC' to CPPFLAGS, so that it isn't necessary to
hardcode this in libavcodec/libopenjpeg{dec,enc}.c.

Finally, check for non-static openjpeg 2.1, too.

This fixes a build problem for MIPS architecture that looks like this:

libavcodec/mips/h264dsp_msa.c:2498:6: error: conflicting types for
‘ff_weight_h264_pixels16_8_msa’
 void ff_weight_h264_pixels16_8_msa(uint8_t *src, int stride,

This bug was introduced by commit bc26fe89:

  avcodec/h264: Use ptrdiff_t for (bi)weight functions

That commit changed the data type of some function parameters in some
function definitions. However, the implementation of those functions in
libavcodec/mips/h264dsp_msa.c wasn't changed accordingly.
