18b95d85f2 libvpxdec: Fix "error: implicit declaration of function ‘av_check_image_size’". 
av_check_image_size() is declared in libavcore/imgutils.h.

When sizeof(uint_fast8_t) >= sizeof(int) there are unintended size effects.

8d370d88e5 Fix VP8 decoder dependencies 
This reverts rev 24674 - the VP8 decoder actually depends on cabac.o.
vp8.c includes vp56.h, which includes cabac.h, which has inline functions
that reference tables from cabac.c.

This fixes compilation with --disable-everything --enable-decoder=vp8.

f311208cf1 VP8: much faster DC transform handling 
A lot of the time the DC block is empty: don't do the WHT in this case.
A lot of the rest of the time, there's only one coefficient: make a special
DC-only transform for that case.
When the block is empty, don't incorrectly mark luma DCT blocks as having DC
coefficients.

6341838f3c Use word-writing instead of dword-writing (with two cached but otherwise 
unchanged bytes) in the horizontal simple loopfilter. This makes the filter
quite a bit faster in itself (~30 cycles less on Core1), probably mostly
because we don't need a complex 4x4 transpose, but only a simple byte
interleave. Also allows using pextrw on SSE4, which speeds up even more
(e.g. 25% faster on Core i7).
