Add (enhanced) patch by Giles Atkinson
Add controlled_exit() to errors when parsing functions.
Add verbose error messages, including line number and
name of the source file.
.lib file handlinmg with its recursive structure probably needs
testing and improvements.
More error messages may need this update.

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 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.
That simplifies code and will be needed for irreversible code model support.

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'.

Restore the deleted unused params to be backword compatible. Handle the case where the d_process instance has a null in vector, so that N_din is zero. This allows the model to be just a pattern generator. Add include to cmproto.h to avoid a forward ref. to an enum type.

Add a code model function cm_exit(const int exitcode).
This function calls controlled_exit(exitcode) to shut

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.

Handle SIGTTIN and SIGTTOU on Unix-like OSs with X11 graphics.
That makes it possible to push ngspice into the background while
plot windows are open: the windows remain responsive.
Discussion on ngspice-users, starting 2023-09-01,
title: "`quit` in Interactive Mode."
Also restore terminal state when forcing exit with SIGINT (control-C).

By default, use the shortest typical delay estimate. This makes the digi_74LS90_74LS42.cir testcase for bug641 behave almost the same as MicroCap 12. In ngspice and MicroCap, the only signal with a glitch is not_y8. The other not_* signals look the same. Setting ps_use_mntymx in .spiceinit will change the delay estimates. See the function set_u_devices_info in src/frontend/udevices.c for the various settings of ps_use_mntymx.

Getting rid of SPARSE for Initial Circuit Matrix creation. Now KLU is totally independent from SPARSE. This opens up the interface for other solvers as well
