Change the code that makes variables from device/model parameters
(spiceif.c) and vectors from variables (vectors.c) so that
array and string-valued parameters and the resulting variables
are handled correctly. Fix a memory leak in converting
array parameters; that requires a change in cplask.c so that
CPL devices behave the same way as others. Add a "device" variant of
the Compose command so that generated vectors are available in scripts.

During setup of the models thre have been search scans in the
linked model list modtab. The time used here grows approx.
quadratically with the number of models. If the numbers get large,
e.g. with the IHP Open PDK, setup time make simulation impractical.
Therefore the linked list modtab has been enhanced by a hash table
modtabhash, which allows linear search time and makes simulation
of a 200k transistor circuit with IHP PDK possible. Already
the setup time for 15k transistor circuits has been reduced.

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.

Efficiency: Remove setting the random seed to behind the options selection
Evaluate '.options cshunt=xx' earlier to allow the following:
Set the option by calling INPpas4() during parsing the circuit,
before .ic is set.
Ckt and Task cshunt are still set, but their values are available
only too late for INPpas4(), but may be used by command 'option'
(w/o parameters) for assessing the options and their values.

implement option 'indverbosity' to control check of inductive systems
default is 2, maximum verbosity
option indverbosity=1
can be used to prevent check for
"incomplete set of couplings"
option indverbosity=0
can be used to avoid the check altogether
set indverbosity=INTEGER
or
.option indverbosity=INTEGER
works as well
