Insert XSPICE bridging devices automatically when an analogue node
has the same name as an XSPICE event node (including digital nodes).
The function Evtcheck_nodes() is replaced by a new version in its
own file.

Initial files for translating Pspice u.. instances and timing models into Xspice equivalents. Standard gates, tristate gates, dff, jkff, dlatch are supported. Compound gates and pullup/down are not done. Makefile and frontend/inpcom.c changes have not been finished. These modifications will be needed to complete integration.

Allow math characters in node names
Add a function ft_getpnames_quotes()
It puts quotes " around tokens xxx, when these are enclosed as
V(xxx) and contain arithmetic characters. V(R*C) becomes
V("R*C"). After settig up the parse tree, the quotes are removed again.
Thus these math character remain part of the node name and are not
parsed as parts of an equation.

With the ngspice gnuplot command, enable x/y contour plots for 2d Cider save file data. Usage: gnuplot <file> xycontour <expr>. xycontour is a new flag which is ignored if the plot data is not from 2d Cider. For contours, only a single plotarg <expr> is allowed. With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored.
