e9d817351b dsputil: Separate h264 qpel 
The sh4 optimizations are removed, because the code is
100% identical to the C code, so it is unlikely to
provide any real practical benefit.

42d3246948 floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

fef906c77c Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. 
Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

8c53d39e7f lavc: introduce VideoDSPContext 
Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context 
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

c73d99e672 Separate format conversion DSP functions from DSPContext. 
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.
