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.

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.

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.
