src/spicelib/parser/inpptree.c, bug fix, B expression of kind `max(0,expr)'
identified and reported by Marcel Hendrix,
expressions of this kind could trigger a segmentation violation.
PTdifferentiate() roughly evaluates to
ternary_fcn(ge0(0-expr), 0, PTdifferentate(expr))
and mkb() optimizes
0 - expr --> unary_minus(expr)
IFeval() invokes PTeval() for the derivative too,
PTeval() looks at the incorrect tree->funcnum
and tries to PTeval for a second argument which is not there,
(unary_minus does not have a second argument)
causing a segmentation fault.

src/spicelib/parse, implement `nint()' (`B' language)

fix `log' in `B' and in `.control', to base e instead of 10
In the B language this can be considered a bug fix.
In the .control language this is a severe change
and breaks backwards compatibility.
In all three languages 'numparam' 'B' and '.control' we now have
ln to the base e
log to the base e
log10 to the base 10
Thus log and log10 is now consistent
with the vast majority of programming languages.
ln is merely for convenience.
very few other languages have it.
I'd like to discourage its usage.
