Finish WL2278 Impl 3 - Dynamic port allocation of cluster nodes.

ndb/include/util/SocketClient.hpp:
  Add SocketClient::set_port(unsigned short port)
  - Sets both m_port and m_servaddr.sin_port
ndb/src/common/transporter/Transporter.hpp:
  Fix set_r_port to call m_socket_client->set_port(port) (if there's a socket client).
ndb/src/common/transporter/TransporterRegistry.cpp:
  Handle non-TCP Transporter nodes correctly
ndb/src/mgmsrv/main.cpp:
  Better document and error check connecting back to our own ndb_mgmd
