Holger Vogt 0e46f6f8a1 remove numerous unsigned int vs. int warnings 
by setting all variables to type int.
Remove redundant function declarations by remmoving some includes
in span.c and vsrcdefs.h
In tmalloc convert int to size_t

Ic, Ib of a positively biased npn.

Add current measurement for all nodes of a device,
e.g. .probe i(Q1) will measure Ic, Ib, Ie (and Is)

Holger Vogt 16f619818e Remove a conflict between the text variable substitution like 
set text = "mytext"
set newtext = new.{$text}
echo $newtext
and the command circbyline, which may have to process strings
containing braces {...} without any change to the string.

Do not call cp_doglob() when command circbyline is executed.

Holger Vogt 2915f8e991 In case of resistor valuues r150 (r + integer number), 
return 150
R2 n1 n2 r150

In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter
R3 n3 n4 r23mod
