Fix a crash found by Brian Taylor: when .plot attempts to plot digital
node history, interpolation may produce an infinite value at digital edges.
Remove vertical edges when interpolating and make some other improvements:
do not calculate a polynomial approximation for unused frames;
center the target x-value in the frame; and do not propogate a reduction
in degree to later frames.

Add new code model function cm_irreversible(). This may only be
called from an XSPICE code model's INIT call and has three effects:
the instance is treated as "hybrid" even when it does not use both
port types; its position in the hybrids array is adusted; and it
is explicitly notifed when called just befoore the end of an
analog time-step.

Convert XSPICE's hybrid_index array to instance pointers.

In dctran.c, call EVTcall_hybrids() (which then calls a subset of
code model instances) only when the current timestep was successful.
That is efficient and means that code models may rely on such calls,
for example a co-simulator may safely advance to the end of the timestep.
The function cm_irreversible() that is mentioned in a comment will be
added in a later commit.

Add a predifined variable 'skywaterpdk' to speed up circuit
loading and parsing.
If set, it removes quoting tokens for params. This requires
that Skywater PDK does adequately stick to the ngspice syntax
to put params in between braces. As far as tests go, it does.
It also set the number of nodes for MSO devices to 4, so no lengthy
search is required.
