[Mimedefang] Make problems: libsm + strlcpy

[Rick Mallett]

One solution is to write your own strlcpy function and add it
to the source for libmilter, or put it in a separate file and
modify the Makefile to compile and link it in. All you need is

size_t strlcpy(char *dst, const char *src, size_t dstsize) {
  if (strlen(src) < dstsize) {
    strcpy(dst,src);
  } else {
    strncpy(dst,src,dstsize-1);
    dst[dstsize-1] = '\0';
  }
  return strlen(src);
}

I didn't test this BTW for syntax errors, but it should work. If
the compiler complains about size_t change it to "int" and it should
work.
