* Fixed issue-1135 (LVS mismatch on parallel devices)
The fix consists of a more elaborate device identity analysis
following the topological matching. In this step, the devices
are identified according to their connections and parameters.
It is important to properly identify devices taking their
parameters into account as well as their connections.
* Second part of issue fixed (inverter chain ambiguity)
* Added test
* Updated tests
* Updated golden test results
* Updated golden test data for Windows

* First attempt to fix. Rather experimental.
* Debugging and bug fixing
The basic issue was a missing break
However, correct computation of cache results for instance-to-instance cluster
interaction is implemented
Plus: identical and overlapping instances are no longer ignored except in the
case of exact duplicates. Otherwise these instance generate dead nets which
are not connected elsewhere.
* Added tests, fixed duplicate cells test, added missing files.
* Code simplification (removed invariant from transformation in cluster-to-cluster interaction cache)
* Skipping cell instance duplicates as some real-world testcases mandate so
* Updated test data
The bug was that while iterating a Region during the gate traversal,
the "select_interacting" was triggering a sort() which changed the
order.
Solution is to pre-sort when iterators are issued also when the
iterator is non-region selecting. This way, plain and region query
iterators can be used together. In addition, the dirty flag scheme
of Cell+Shapes was cleaned up a little for bboxes.
Previously: matching of blackbox pins was enforced
by using pin names for passive nets in the compare.
Problem: no match was achieved when pins are not
named or not named consistently.
In this case, it's desirable to treat them as
ambiguous.
The new solution is to let the ambiguity resolver handle
that using an extended definition of the net names:
it will take the pin name into account if an unnamed net
is attached to a pin.
In addition, net ambiguities are projected to pin
equivalence now. This also will propagate symmetry
through nested blocks (dbNetlistCompareTests:20_BusLikeConnections).
