Refactoring of CK_2 Filtered_bbox_circular_kernel_2: 

- The three classes Circular_arc_2, Circular_arc_point_2 and Line_arc_2
    now have a proper base class with bboxes,

  - The functors of Fb_ck_2 now directly use the functors of Ck_2 (without
    bbox filtering) templated by Fb_ck_2: that avoids all creations of
    temporary objects to convert between types CGAL::Foobar_2<CK_2> and
    CGAL::Foobar_2<Fb_ck_2>.

  - The number of functors in bbox_filtered_predicates has been reduced
    quite a lot: all functors that were not using bboxes have been
    removed. They were just forwarding all there calls to the functors
    without filtering. That was useless (and created a lot of temporary
    objects).

As a side effect, Fb_ck_2 now works even with -DCGAL_CFG_MATCHING_BUG_6
(VC++), because of the removal of the temporary objects.
