cosmetic: Make parameter lists uniform

The non-sse implementation and the sse implementation of the convert
and convolve functions have different parameter lists. This makes it
difficult to use function pointers in order to select the right
function depending on the SSE-Level and CPU.

This commit uniformizes the parameter lists in preparation for
planned runtime cpu detection support
