Clément Bœsch d0e132bab6 Merge commit '1bd890ad173d79e7906c5e1d06bf0a06cca4519d' 
* commit '1bd890ad173d79e7906c5e1d06bf0a06cca4519d':
  hevc: Separate adding residual to prediction from IDCT

This commit should be a noop but isn't because of the following renames:

- transform_add  → add_residual
- transform_skip → dequant
- idct_4x4_luma  → transform_4x4_luma
