A small cnode.
To be called from the test case erl_eterm_SUITE:cnode_1.
1) Set up connection to node 'test_server' on the same host.
All sends are done to a registered process named 'mip'.
2) Create a long ref and send it.
3) Create a pid for ourselves and send it.
4) Receive a message.
5) Send back the message part of the message.
6) Send back the 'to' part of the message.
