Do the difference, returning SAD

| mv | the motion vector being used |
Implements dirac::BlockDiffUp.

| ) | [virtual] |
Do the actual difference, overwriting the best MV so far if appropriate, and bailing out if we do worse
| dparams | block parameters |
| mv | the motion vector being used |
| mvcost | the (prediction) cost of the motion vector mv |
| lambda | the weighting to be given to mvcost |
| best_costs | the best Lagrangian costs obtained yet |
| best_mv | the MV giving the best Lagrangian costs so far |
Implements dirac::BlockDiffUp.
