streqvmap - Set the character mappings for the streqv functions

       Set  the  character  mapping.   If  the count (ct) is set to zero, then the map is cleared by setting all
       entries in the map to their index  value.   Otherwise,  the  "From"  character  is  mapped  to  the  "To"
       character.   If  ct is greater than 1, then From and To are incremented and the process repeated until ct
       entries have been set. For example,
           streqvmap('a', 'A', 26);
       will alter the mapping so that all English lower case letters will map to upper case.

       This function name is mapped to option_streqvmap so as to not conflict with the POSIX name space.
