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.

Make the special "noglob" variable work. To preserve previous behaviour
change the default value from true to undefined (meaning false).
Also fix a misleading comment in glob.c.

Make special interpreter variable "noglob" behave as documented:
globbing is off by default. An incompatible change, but previous
behaviour can be restored by "unset noglob" in .spiceinit.

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).

Fix a bug in the "help" command. Some commands have no action function,
so the function pointer should not be used to detect the end of the table.

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.
