Moved some math macros (sqr, lerp, clamp) to libslic3r.h

Browse source 
Added UNUSED macro to libslic3r.h, used it to reduce some compile warnings.

Split the Int128 class from Clipper library to a separate file,
extended Int128 with intrinsic types wherever possible for performance,
added new geometric predicates.

Added a draft of new FillRectilinear3, which should reduce overfill near the perimeters in the future.
