  port string to int conversion using sscanf

  There are several instances where a port is parsed
  from a uri or some other source and converted to
  an int value using atoi(), if for some reason the
  port string is empty, then a standard port is used.
  This logic is used over and over, so I created a function
  to handle it in a safer way using sscanf().
