ssedetect: Introduce function pointer structs

In order to defer to the currently applicable (CPU and SSE-Level dependant) implementation, a struct with function pointers is needed. The struct is filled up with pointers that point to the implementation that is suitable for the current PCU model.

This commit ads such function pointers in preparation for planned runtime CPU detection support. The decision which funcion is picked is still static (made at compile time) and follows the same rules as before. Automatic runtime CPU detection will be added with the following commits.

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

WIP: Turn off native architecture builds

The compiler option -march=native instructs the compiler to auto-optimize the code for the current build architecture. This is fine for building and using locally, but contraproductive when generating binary packages.

This commit introduces more general options and also removes --with-sse from the default configure options.

The Makefile.am now uses the -msse4.1 option as a default. This is still a problem as some compilers might have problems. We should integrate SIMD_FLAGS here, this is why this is still work in progress.
