vp56: Remove clear_blocks call, and clear alpha plane U/V DC only
...
The non-alpha and alpha-Y planes are cleared in the idct_put/add()
calls. For the alpha U/V planes, we only care about the DC for entropy
context prediction purposes, the rest of the data is unused.

lavc: introduce VideoDSPContext
...
Move some functions from dsputil. The idea is that videodsp contains

Currently, it contains emulated_edge_mc() and prefetch().
