Also, try to see if it is possible to use vertex conflict
instead of the orientation Linf test in insert_third.

The changes fix several bugs.
One choice involves a specific choice of bisectors to
compute the vv of three segments, that gives priority
to axis-parallel segments and segments that have a common
endpoint.
Maybe these changes should be also translated to vring.

Problem with the following input is fixed now:

s -50 -20 0 +30
s 0 +30 +50 -20
p -20 0

New predicates in Basic_predicates_C2.h:
is_site_h_or_v
is_site_horizontal
is_site_vertical
These predicates are used in several files in classes that are derived
from Basic_predicates_C2.

This fixes the bug for the input br10.cin:
s -100 110 0 100
s 200 80 -110 -190
p 0 0
s 0 100 200 80
However, it seems we must also check if things
are in the same quadrants.
The bug for input br20.cin is still there:
s -100 130 0 100
s 200 80 -110 -190
p 0 0
s 0 100 200 80

This fixes the bug for input:
~/Dropbox/cgal/demo/Segment_Delaunay_graph_Linf_2/September/br10noseg.cin
s -100 110 0 100
s 200 80 -110 -190
p 0 0
In particular, vertex conflict of (M,CM,DE) with F now returns -1,
where M=(0,100), C=(-100,110), D=(200,80), E=(-110,-190), F=(0,0).
Maybe the same fix has to be done for qref.

There was a problem with the following input.

For A=(0,0), B=(100,0), C=(200,200), D=(200,250),
we had erroneously fecf(BC,A,AB,BD,-1) returning
false. The correct answer is true and it is fixed now.

When q is point, we have the following assertion (again):
bool is_q_tsrc = same_points(q, t.source_site());
bool is_q_ttrg = same_points(q, t.target_site());
CGAL_assertion(not (is_q_tsrc or is_q_ttrg));

This is useful for use of Bisector_Linf in constrcutions.
I have also added support for Sign and Boolean.

It solves the bug for the following input:
$ cat ~/Dropbox/cgal/demo/Segment_Delaunay_graph_Linf_2/September/5segA2.cins 0 0 0 100
s 0 100 100 100
s 0 0 100 100
p 50 50
p 50 100
s 50 50 50 100
It has to be further tested when the line l comes from a segment t which
is a strict subset of a side of the Linf square related to vertex vv.

I have only kept in an include directory at the root
the change in arrangement point location.
This change also requires to use some special local
includes in CMakeLists.txt files. I will do it in a
subsequent commit.
