Upon a warning on a model issue, ngspice should not bail out,
even if strict_error is set, as typically the simulation will
run and foreign models often have additional unsupported, but
less important parameters.
It shall however, exit if the simulation is interrupted due
to an error and strict_errorhandling is set.

Replace the logicexp parser with infix to postfix translation followed by evaluating the postfix. logicexp.c is now shorter and easier to understand and maintain. Also, operator precedence expression parsing conforms to the PSPICE rules. Thus, a & b | c is understood to mean (a & b) | c, for example.

There are approx. 47 out of 1455 subckts in PSPICE 9.1 libraries which contain X* subckt calls together with zero or more U* instances. Now this type of subckt can be translated to XSPICE.

Several PSPICE 9.1 evaluation digital libraries contain timing .model statements at the global level for subckts with U* instances that reference those models. By specifying "set ps_global_tmodels=1" in .spiceinit an extra pass inside u_instances() will collect those global timing models for use in subckts. Report errors detected when ngspice parses a LOGICEXP but has not added support for operator precendence. Include a hint of how to fix those errors by inserting parentheses. This error only occurs in 10 of 585 cases in the libraries. Note that inpcompat.c has been saved as a unix filetype.

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.

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.
