3281d823cd intrax8: Change type of array stride parameters to ptrdiff_t 
ptrdiff_t is the correct type for array strides and similar.

Also rename all such parameters to "stride" for consistency.

922b7e6d86 intrax8: Use local destination buffers 
These buffers are just a way to store frame pointers and be able to
modify them without touching the original ones.

The two dependent decoders (WMV2 and VC1) do not need special care for
these fields: the former does not seem to use the dest buffers, while
the latter reinits them every time to the current frame data buffers.

So only keep a local copy rather than the one from mpegvideo.
