For all encoders and all decoders except MPEG-4 the unquantize functions to use don't change at all and therefore needn't be kept in the context. So discard them after setting them; for MPEG-4, the functions get assigned on a per-frame basis. Decoders not using any unquantize functions (H.261, MPEG-1/2) as well as decoders that only call ff_mpv_reconstruct_mb() through error resilience (RV30/40, the VC-1 family) don't have the remaining pointers set at all.
