Add inv_strpbrk() function and convert equivalent sindex() calls

inv_strpbrk() is the inverse of the standard function strpbrk().

Calls to sindex() where both strings are not NULL and the second string begins with ^ are equivalent
to calls to inv_strpbrk() (but without the ^).  Convert those calls.
