ObjectInputStream.java (readObject): Added code to conditionally dump out the serialized data.

Browse source 
* java/io/ObjectInputStream.java (readObject): Added code to
	conditionally dump out the serialized data.
	Handle ENDBLOCKDATA case a bit more gracefully since the current
	behavior doesn't seem to work as expected.
	(readStreamHeader): Added code for serialized data dumper.
	(readNextBlock): Ditto.
	(readFields): Ditto.
	(dump): New private static field for turning on/off dumper.
	(setDump): New native method.
	(dumpElement): New native method.
	(dumpElementln): New native method.
	* java/io/natObjectInputStream.cc (setDump): New method.
	(dumpElement): New method.
	(dumpElementln): New method.

Serialization dumper.  Enable by configuring with --enable-libgcj-debug
and calling java.io.ObjectInputStream.setDump(true) in your test program.
The output will be generated as the object is deserialized (i.e. the
readObject() method is executed).
