ASRC (B-Source) error message is cryptic, as it does not tell
which B-Source failed.
Add a hint to the ASRC error message on the name of the
B-Source instance.

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.

Add new SOA parameters (safe operating area) for BJT.
We now scan for max of Ic, Ib, power, taking into
account the max allowed temperature, using the thermal
resistance rth0 model parameter between juntion and ambient.
Two user options are there: If rth0 is given, we calculate
a derating of the max power allowed.
Without a constant max power according to model param pow_max
is assumed.
The new model parameters for the bipolar model are:
pow_max, ic_max, ib_max, te_max, and rth0, in addition
to the already existing vbe_max, vbc_max, adn vce_max.

Some update to SOA for a diode:
Limit output to four digits
Add power and temperature limits.
Derating with self-heating, or with fixed temperature,
or no derating at all, selectable by setting model parameters.
