  Log Message:
  -----------
  Set POLLRDHUP on Linux when polling rtpproxy's socket to drain
any unclaimed data. This seems to be necessary on TCP sockets
otherwise poll() appears to hang indefinitely if rtpproxy has been
terminated despite timeout being set to 0 (i.e. don't block).

With this flag set the disconnect is properly detected and socket
is re-connected after configured timeout.
