Michael Niedermayer b05830169d Merge commit 'b9ba5253dd1232be4b48cfe61c31ff4b3de3d10a'
* commit 'b9ba5253dd1232be4b48cfe61c31ff4b3de3d10a':
  dsputil: Move copy_block functions to a separate header
  dsputil: Drop unused functions copy_block{2|4|16}

No functions are droped because they are used in several places.
