This is the value actually used by the decoder in speed-critical code.
The encoder uses these tables only in init code.

The minimum weight value is 32 so this test can be skipped for the
10-bit case.  Overall speedup 3-4%.

High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not.  This creates a conflict with the templated
functions operating on DCTELEM data.  This patch adds a field
allowing the caller to choose the element size in dsputil_init()
and adds the required functions.

On some platforms EINVAL could be positive, ensure we return negative values.

This ensures the linker picks the just built libraries even
if LDFLAGS for some reason contains -L flags pointing at
other directories containing libav libraries.

Using Sun's compiler on Solaris, -xc99 is as much a linker flag as a
compiler flag, so add it to LDFLAGS.

G729_BITEXACT is never set, so the code is all dead code.

Mpegvideo would free frames as soon as they're not the next or prev
picture. This is fine for a single-threading model, but fails miserably
in a system where pictures can be referenced (as e.g. last/prev pic)
in other threads. Keeping track of ownership of pictures keeps image
references (e.g. motion vectors, or the reference of a motion vector)
alive as long as the picture data itself is alive.

This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.

Use of these has been broken ever since the h264 idct was changed
to always use transposed inputs.  Furthermore, they were only
ever used if some *other* non-default idct was requested.
