Log Message:
Change the "string" argument to evalstring() and setinputstring()
from being "char *" to being "const char *".

This is needed for a forthcoming change which needs to pass a const char *
to evalstring (and through it to setinputstring) and be assured that
nothing will alter the characters in the string supplied.

This is (aside from the additional compile time protection provided)
a no-op change, all evalstring() does with its string is pass it to
setinputstring() and all that does with it is determine its length
(strlen() which expects a const char *) and assign the string pointer
to parsenextc which is already a const char * - there never has been
any reason for these two functions to not include the "const" in
the arg declaration -- except that when originally written (early
1990's) I suspect "const" either didn't exist at all, or wasn't
supported by relevant compilers.

NFCI.   Most probably (though I didn't check) no binary change at all.
