fmt_ulong - write an ASCII representation of an unsigned long integer

       fmt_ulong  writes  an ASCII representation ('0' to '9', base 10) of source to dest and returns the number
       of bytes written.

       fmt_ulong does not append \0.

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

       For convenience, fmt.h defines the integer FMT_ULONG to be big enough to contain every possible fmt_ulong
       output plus \0.
