  Fix a possible infinite loop in SDP parsing during glare situation.
  
  There was a while loop in get_ip_and_port_from_sdp which was controlled
  by a call to get_sdp_iterate. The loop would exit either if what we were
  searching for was found or if the return was NULL. The problem is that
  get_sdp_iterate never returns NULL. This means that if what we were
searching
  for was not present, the loop would run infinitely. This modification of
the
  loop fixes the problem.
