05da586fef dv: move inverse weight tables to decoder
The encoder has its own tables and does not access the idct_factor
member of the DVVideoContext structure.

6fe02d25ee dv: fix weight table for 2x4x8 transform
The coefficients must be in the appropriate zigzag scan order.
Also fix their values at the same time, as they were pretty wrong.

Fixes ticket #2970.

1086f09da3 dv: more precise weight table for 8x8
It is derived from the actual equations of the specs. In
particular, it is closer to the inverse of what the encoder uses.

fate tests accordingly updated.
