fmt_strm - write multiple ASCII strings

       fmt_strm  copies  all  leading  nonzero  bytes  from  source and following function arguments to dest and
       returns the number of bytes it copied.

       fmt_strm does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_str returns the number of bytes it would  have  written,  i.e.
       the number of leading nonzero bytes of source and following function arguments.
