Removing unused models takes much more time than keeping them
for large circuits.
Probably a hash table may help here (t.b.d.).

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.

Evaluate function gauss() in B sources. This is required when
in .model files the tokens 'temper' and gauss() coexist, because

This is a re-write of the PWM generator.
It is modelled according to the new d_OSC by Giles Atkinson.
Here frequency is fixed and duty cycle is controlled by an
analog input.

This patch fixes a bug when shared library uses XSPICE:
Don't subtract delta twice, when breakpoint is active
and step is rejected.

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.

title: "`quit` in Interactive Mode."
Also restore terminal state when forcing exit with SIGINT (control-C).

Some KLU warnings are useless for the normal user, as she or he
does not have any means to further analyze or repair the issue:
Warning: KLU ReFactor failed. Factoring again...
Warning (ReFactor Complex): KLU Matrix is SINGULAR
Numerical Rank: %d\n
Singular Node: %d\n
So print these messages only in debug mode.

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.
