    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.
