New math util funcitons:
- equals_v2v2
- project_v2_v2v2
- isect_seg_seg_v2_point
which would be necessery for my further multires interpolation commit
M_Geometry_LineIntersect2D now uses isect_seg_seg_v2_point(). Behaviour of this
function was changed a bit -- it haven't returned intersection point in several
cases when two segments are making angle.
