streqvcmp - compare two strings with an equivalence mapping

       Using a character mapping, two strings are compared for "equivalence".  Each input character is mapped to
       a  comparison  character  and  the  mapped-to  characters  are  compared for the two NUL terminated input
       strings.  This function name is mapped to option_streqvcmp so as to not  conflict  with  the  POSIX  name
       space.

       str1   first string

       str2   second string

       none checked.  Caller responsible for seg faults.
