* 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

Wildcard expansion feature on layer mapping
Finished feature, added doc and test.
The solution is to use placeholder indexes for the
layer mapping which are substituted by the real
layers when they are encountered.

Preparations for new feature: introduce relative and wildcard target layer specs
The cause for the problem was that the layout got updated
while iterating causing the mess within the iterator.
This solution is to lock the layout while an iterator
is present. This happens for various Cell and Shapes
iterator, so it's a major enhancement.
