avcodec/vc1: implement interlaced out-of-bounds reference pixel replication

Browse Source 
The existing implementation did out-of-bounds reference pixel replication for
progressive reference frames. In interlaced reference frames both the even and
odd line on the horizontal edges need to be replicated.

Fixes #3262.
