## Summary of Changes
While experimenting on self-intersecting polyhedral surfaces, I met two
bugs:
* `edge_min_size` was not enough taken into account in
`Protect_edges_sizing_field`,
* `edge_distance` was missing the information of which `curve_id` the
edge belongs to (available using internal code)
causing crashes.

Fix the case of surfaces with borders. Then they may be incident to only
the unbounded volume which so far was ignored.

## Summary of Changes
Some non intersection is wrongfully detected as an intersection for the
Line_3 Ray_3 combination. Here is an illustration:
The base code is :
```cpp
if(!do_intersect(l, r.supporting_line()))
return false;
typename K::Coplanar_orientation_3 pred = k.coplanar_orientation_3_object();
CGAL::Orientation p0p1s = pred(l.point(0), l.point(1), r.source());
if(p0p1s == COLLINEAR)
return true;
CGAL::Orientation stp0 = pred(r.source(), r.second_point(), l.point(0));
if(stp0 == COLLINEAR)
return Ray_3_has_on_collinear_Point_3(r,l.point(0),k);
return (p0p1s != stp0);
```
The supporting line of the ray intersects the line, and then nothing is
collinear, so we check L0,L1,R1 vs R0,R1,L0, which are of opposite sign
so there is an intersection... but there is none.
This check is very similar to what is done in Ray_3-Ray_3, where it is
correct.
I did a naive fix for now: without loss of generality we can go to the
configuration below
and so we have an intersection as long as the ray "points" in the other
slab wrt to the line. And so, in coplanar orientation checks, if the
orientation L0,L1,R0 differs from L0, L1, (L0 + (R1-R0)).
I feel like I could probably skip at least a translation by having
something like Coplanar_orientation(P3, P3, P3, V3), and maybe even
more...
