Fix bug #602 "Warning message trying to linearize a transient analysis vector"
by changing the way "ngspice -a" (autorun option) works. The inserted code
now checks whether a simulation has already run by examining $curplot
before forcing "run". Also at most one simulation is forced to run.

* Look at only the first 2 nodes of S and W switches
and F and G controlled current sources, measure current
with = voltage source added to second node. So we get

Extend the output and partial derivatives of the output from the 2/3-D
table lookup models (XSPICE) continuously outside the defined
rectangle or cube, as it may help convergence and avoid ambiguity caused
by rounding at the boundaries. See bug #591 "Wrong 2D table model output".
The value is that of the nearest point in the region while the reported
derivative is ramped to zero outside the boundaries.
Also fixes incorrect output at the upper limit in each dimension.
