Matthias Koefferlein 99f111fe01 Attempt to achieve reproducibility between MSVC and gcc 
Applies to dbHierProcessor.cc:

The issue was related to std::unordered_set/map which
(as the name says) is not ordered. The output of the
boolean core computation step is currently dependent
on the order (it's single pass), hence the order of
the contexts matters.

Using ordered sets where possible and explicit
sorting might help.

Matthias Koefferlein 57305977a4 Spice writer delegate fix 
- Changed to const & objects in the Spice writer delegate
  to non-const & for Ruby/Python reimplementation (as const/non-const
  ambiguity is an issue for Ruby/Python we cannot efficiently
  work with const refs)
- Updated test data because the previous implementation wasn't
  using refs but rather copies of device and device class
  objects.

Matthias Koefferlein 30e26c4f96 Avoid an issue with virtual functions 
Reimplementing virtual functions with
"const &" arguments wasn't behaving as
expected because these arguments were
copied.

Now, "const &" for arguments (in virtual
function reimplementation) is not implemented
as a copy.

In addition, now it's possible to declare
results as references always (also if const &).

See gsiTest.cc:1078 for example:

  //  gsi::arg_make_reference makes the function's return value
  //  always being taken as a reference
  gsi::method<C_P, const CopyDetector &, const CopyDetector &, gsi::arg_make_reference> ("pass_cd_cref_as_ref", &C_P::pass_cd_cref)

Matthias Koefferlein 9c607d7663 Added a first version of the layout to netlist extraction feature 
The main entry point is RBA::LayoutToNetlist which is the
GSI binding for the layout to netlist extractor. For a first
impression about the abilities of this extractor see the
Ruby tests in testdata/ruby/dbLayoutToNetlist.rb.

The framework itself consists of many classes, specifically

- RBA::Netlist for the netlist representation
- RBA::DeviceClass and superclasses (e.g. RBA::DeviceClassResistor and
  RBA::DeviceClassMOS3Transistor) for the description of devices.
- RBA::DeviceExtractor and superclasses (i.e. RBA::DeviceExtractorMOS3Transistor or
  the generic RBA::GenericDeviceExtractor) for the implementation of the
  device extraction.
- RBA::Connectivity for the description of inter- and intra-layer connections.
