c6b281685d netlist: Compile with float/double floating point. [Couriersud]
Added ability to compile using float instead of double. Specifically the
the solver as well as the infrastructure now can have their own floating
point type. Currently this is only an academic exercise since
numerically demanding circuits like kidniki only work with double/double
support. Using float here is pushing numerical stability over the
limits.

The long term design goal is too have the matrix type (double/float)
being a parameter.

97b6717027 (nw) Clean up the mess on master
This effectively reverts b380514764 and
c24473ddff, restoring the state at
598cd52272.

Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline.  When things like this happen, it wastes
everyone's time.  I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.

ca11021d73 Netlist:
- refactored reverse polish notation evaluator into own source files.
- added function parameter to current and voltage sources VS and CS.
  You can now use those to e.g. produce a sine wave.
- Changed code to allow devices to optionally be treated as dynamic or 
  timestepping devices.
