Reduce risk of DRC polygon split artefacts in deep mode (#722) 
* Fixed a segfault with simple 'klayout -v'

* is_halfmanhattan polygon predicate, confine polygon splitting to halfmanhattan

Splitting any-angle polygons for area reduction in the
deep processor creates a risk of introducing grid-snap
artefacts. Hence we avoid this.

Issue 718 (#719) 
* WIP: first part of fix - generation of hole cutlines

First problem was that hole cutlines got extended
over the whole length and sometimes lead to coincident
edges which are difficult to resolve for the polygon
cutter.

* Refined solution, fixed #718

- disabled elaborate hole insertion procedure for now as the
  performance impact has to be assessed yet and the new scheme
  will break many tests
- stricter rejection of ambiguous configurations in the polygon cutter
- fallback is boolean AND now since there is no need to re-invoke the
  polygon cutter (we can't do so as we made it more strict).
  Performance-wise we replace a merge by an AND step which may even be
  faster the output is smaller and the polygon cutter does not need
  to be re-invoked.

* Compatibility with other STLs

Matthias Koefferlein 9cf0a9e659 Major enhancements for DRC feature (universal DRC) 
Main issue: universal DRC scheme and rectangle filtering/opposite filtering/shielding.

The space function required some enhancements to accomodate symmetric interactions.
Now there are symmetric edge pairs. Space initially runs twofold (primary to foreign)
but produces symmetric edge pairs. These are filtered later unless converted before.
