S-parameters in ngspice
With this commit the patch provided by Alessio Cacchiatori the S-parameter is completed:
Noise simulation added with C matrix output
Y and Z matrix output enabled
To allow compiling with gcc, the dense.h inline functions have been put into denseinlines.h

Update to plotting of event nodes:
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).
Still missing: y axis labeling (no numbers, but node names).

Add a flag 'alle' (all event nodes) to the plot command (and maybe others).
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.
