Matthias Koefferlein cef96902ad Boundary for circuits, reverted automatic generation of global pins
- global pins have been generated for device cells too and lead
  to implicit pins which may not be desired. The original problem
  was how to make abstract circuits comparable. This has to be
  solved differently.
- Circuit boundaries are good for displaying the boxes for
  abstract circuits

Matthias Koefferlein 993ef78575 WIP: some cleanup/enhancement
General topic: abstracts and swappable pins.
Issue: we work bottom up and assign pins. This is the
basis for net graph building. But swappable means those
pins can change. The compare works fine, but debugging
output is strange: as the pin assigned is fixed, the nets
found to be attached to a circuit might not fit any
proposed pin pair (which does not contain swapping).

The problem gets worse with abstracts.

The enhancements are
- Such cases generate only warnings in the browser
  and the message says swapping might be the case
- Floating nets are treated differently. This should
  lead to a better performance for abstracts/black boxes,
  but in case of disconnected pins (due to wire errors),
  floating nets happen to create mismatches in the nets above.
- Net graph building does not consider swappable nets. In
  case of two swappable pins this wouldn't be an issue, but
  for more than two this would create ambiguities and
  prevent topological matching.

Plus: Debug output option for net graph

Matthias Koefferlein 624811d55e WIP: fixed a basic issue with empty layers
Previous: empty layers occupied a special layer in the DSS
But what when empty layers are required as outputs?
ONE layer isn't good -> would overwrite the layer and it's
no longer empty for others.
So we need to keep the layers separate.

Matthias Koefferlein 0d623bc57a Avoid netlist extraction issues with duplicate instances
So far, duplicate instances have lead to net propagation
into parent cells and floating nets. This is fixed by ignoring
duplicate instances where possible.

Matthias Koefferlein ebd00c186b Enhancements for net export feature
- some refactoring
- better performance (was slow because layer iteration
  was done outside of loop and recursive cluster iterator)
- with selected nets, only the required hierarchy is
  produced. For this a new argument is added to
  LayoutToNetlist::create_cell_mapping (nets) which
  allows selecting the nets for which a cell mapping
  is requested
