Enable command 'optran' in spinit or .spiceinit,
when the circuit is not yet loaded.
Then the optran data are stored in static variables,
until optran is called again with arg NULL from inp.c,
to set the data in ft_curckt->ci_defTask.

Transient op calculation added to the standard operating point code.
When standard iteration, gmin stepping and source stepping fail,
try a transient simulation (like tran with uic option) to
determine the op. Implemented for AC and Tran simulation.

Efficiency: Remove setting the random seed to behind the options selection
Evaluate '.options cshunt=xx' earlier to allow the following:
Set the option by calling INPpas4() during parsing the circuit,
before .ic is set.
Ckt and Task cshunt are still set, but their values are available
only too late for INPpas4(), but may be used by command 'option'
(w/o parameters) for assessing the options and their values.
