[buffer][math] check for inf when checking on equals
...
This fixes an error in buffer for geometries with extreme coordinate differences
(though the generated buffer is not correct then)

[buffer] Fix calculation of the number of points. For an angle of 125 or more,
...
no points in between were generated, which was erroneous.
Thanks to Menelaos for spotting and Adam for the calculation
This changes some of the unit test results, because in some cases a point in between
is generated now, creating a larger polygon

[buffer] fix the case where a side was skipped because detected as equal, followed
...
by an end-cap. This caused further problems. Detection of empty sides is now delegated
to the strategy

[buffer] major fix: we now create concave helper-pieces differently
...
In the past there was one with a straight line going from one piece to the next.
Now there are two, going from one piece to the point on the geometry, and the
second going from the point on the geomety to the next piece.
They are now zero-volume.
They fix:
1) crossings of sides with flat-ends (unit-test cases curve, field_sprayer, bend_near_start)
2) joins with limited number of points (unit-test cases concave_b_rough, italy_part, nl_part)
3) joins with large distances
4) many self-intersections on remaining aimes-cases

[buffer][fix] fix output for generated linestrings with two equal points only
...
It now simplifies first and removes second point if necessary. Also it is
defensive such that generation is stopped if length is 0.
Including unit tests.

the default without changing the tests.
This only changes the parameter / involves many lines but nothing else is changed.
