  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

1f821750f0 hevcdsp: split the qpel functions by width instead of by the subpixel fraction 
This should allow for more efficient SIMD.

Keep the C versions as they are now, to allow the compiler to inline the
interpolation coefficients.
