Synchronous API for RPC clients
This is a synchronous client that suffices for most applications of RPC.
type 
The type of simple clients
val create : Rpc_client.connector -> Rpc.protocol -> Rpc_program.t -> tCreate a simple client that connects with the given server using the given protocol type. The program argument specifies the remote program.
val call : t -> string -> Netxdr.xdr_value -> Netxdr.xdr_valuecall simple_client procedure_name procedure_arg:
 Call the procedure with the given name and the given argument. Returns
 the result of the procedure on success; otherwise raises an exception.
Note that it is possible that the connection is aborted and the
 client is reset. In this case call raises an exception but it is
 currently difficult to recognize this case.
 Other reasons may be that the server refuses the call (e.g. because
 of missing authentication).
Frequent exceptions:
Rpc.Rpc_server condition:  The server did not like the call;
                                the 'condition' explains whyRpc.Rpc_cannot_unpack reason:  Got a badly formatted message.Rpc_client.Message_lost:   The stream ended before there was any
                                reply (perhaps not even the call could
                                be sent over the stream)Rpc_client.Message_timeout: There was no reply for the specified
                                period of timeRpc_client.Communication_error x:
                                An I/O error or a serious internal
                                error happened
 Failure s:                   Mostly: The internal state of the client
                                does not allow to do another callNote that only the Rpc_server exception has clear semantics as it is
 known that the procedure has not been invoked.
 It is a good choice to shut down the connection if one of the other
 exceptions happens. (Note that the connection may already have been
 shutted down, but it is ok to shut down twice.)
val shut_down : t -> unitShut the connection down. After the client has been shutted down, it is not possible to call further remote procedures. Throw the client away and create a new one if you want to continue.
