Defines: strinstr()
strinstr(src, pat) looks for an instance of pat in src. pat is not a
regex(3) pattern, it is a literal string which must be matched exactly.
The result 0 if the pattern was not found else it is the start char of
the pattern counted from the beginning of the string, where the first
char is 1.
