Peter Oberparleiter d8e5bc07aa libutil: add function to concatenate a format string in place ...

Add function util_concatf() that appends the result of a format string
expansion to the end of an existing string while taking care of the
required memory allocations.

Usage example:

  char *str = NULL;

  util_concatf(&str, "list:");
  for (int i = 1; i <= 3; i++)
    util_concatf(&str, "%spart%d", (i > 1 ? "," : ""), i);
  printf("%s\n", str); /* list:part1,part2,part3 */
