fmt_ip6_flat - write a formatted ASCII representation of an IPv6 number

       fmt_ip6_flat  formats  an  IPv6  number in a flat ASCII representation from ip and writes the result into
       dest. It returns the number of bytes written (always 32).

       This representation does not contain colons and is meant to be easily machine-readable.  Use fmt_ip6  for
       the  normal  (standard)  representation.   This function is meant for places which use colons to separate
       fields and thus have problems interpreting the standard IPv6 notation.

       If dest equals FMT_LEN (i.e. is zero), fmt_ip6_flat returns the number of bytes it would have written.

       fmt_ip6_flat does not append \0.

       For convenience, ip6.h  defines  the  integer  IP6_FMT  to  be  big  enough  to  contain  every  possible
       fmt_ip6_flat output plus \0.

       #include <libowfat/ip6.h>

         char buf[IP6_FMT];
         char ip[16];
         buf[fmt_ip6_flat(buf,ip)]=0;
