Add calls to mgmd after setting up connections. (not fully functional yet, checkin for pull) ndb/include/mgmcommon/ConfigRetriever.hpp: add get_mgmHandle() member function ndb/include/transporter/TransporterRegistry.hpp: Add remoteNodeId parameter to add_transporter interface add get_transporter() and get_localNodeID() these are required for getting the right information out of TransporterRegistry to inform mgmd of what ports we use to connect to other nodes. ndb/src/common/mgmcommon/IPCConfig.cpp: call add_transporter_interface with the new nodeId2 parameter ndb/src/common/transporter/TransporterRegistry.cpp: Implement additional (remoteNodeId) parameter in add_transporter_interface Implement get_transporter() ndb/src/kernel/main.cpp: Call ndb_mgm_set_connection_int_parameter() to tell mgmd what ports we use to connect to other nodes. ndb/src/kernel/vm/Configuration.hpp: add get_config_retriever() ndb/src/mgmapi/mgmapi.cpp: Add DBUG_ENTER call to ndb_mgm_set_connection_int_parameter ndb/src/ndbapi/TransporterFacade.hpp: Add get_registry() ndb/src/ndbapi/ndb_cluster_connection.cpp: Add call to ndb_mgm_set_connection_int_parameter to tell mgmd what ports we use to connect to other nodes.
