	* gnu/java/rmi/server/UnicastConnectionManager.java
	(startScavenger): Set the client connection manager to daemon
	state because it may block clients until TIMEOUT is reached
	when they are exiting.

	* gnu/java/rmi/RMIVoidValue.java: New file for a class representing
	a void return.

	* gnu/java/rmi/server/UnicastRemoteCall.java
	(DummyOutputStream): Add a boolean before each written field to
	know whether it is a primitive.
	(releaseOutputStream): Flush parameters at write time.

	* gnu/java/rmi/server/UnicastServerRef.java
	(incomingMessageCall): Return a RMIVoidValue if no value is to be
	returned.

	* gnu/java/rmi/server/UnicastServer.java
	(incomingMessageCall): Do not write a returned object if it is
	a RMIVoidValue.
