  Log Message:

  Keep sending datagrams while we have data to send

If we've got more data to send than will fit in a single datagram we should
keep generating those datagrams until we've sent it all.

  Log Message:
  -----------
  Don't keep creating CONNECTION_CLOSE frames

If we want to send a CONNECTION_CLOSE frame then one is enough unless we
are scheduled to send another one. Now that we can create more than one
datagram in one go this is now required.

  Test that we send multiple datagrams in one go if appropriate

If we have enough data for more than one datagram then we should send more
than one datagram
