Subject: [PATCH] b=1348 r=shaver

- send correct handle during reconnect.
- the client now cleans up the dlm export with class_disconnect()
- removed remaining references to imp_export, as it was unused
- fixed ptlbd to use new connection protocol
- rename ptlrpc_import_{connect,disconnect} to client_import_*
- cleaup debugging messages
