Send packets to remote node only via the send thread to avoid possible
races - in this case a keepalive packet was send from wrong thread which
lead to connection dropping, because of corrupted packet.

Fix it by sending keepalive packets directly from the send thread.
As a bonus we now send keepalive packets only when connection is idle.
