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.

Sparse 1.3 is the matrix solver if no option (sparse or klu) is given.
...
KLU is selected by 'option klu'
If both 'option klu' and 'option sparse' are given,
the last one executed determines the solver.
'option sparse=0' de-selects spares, i.e. selects klu.
'option klu=0' de-selects klu, selects sparse.
'option klu=1' has the same meaning as 'option klu'.
'option sparse=1' has the same meaning as 'option sparse'.

of source files if make was accidentally used in the source tree.
That caused the original bug to return. Fix the problem by deleting
the generated source files by name (no such files exist in source.

unnecessary after a chenge to cmpp.
