ObjectInputStream.java (readFields): Turn off readDataFromBlock while reading via GetField. 

* java/io/ObjectInputStream.java (readFields): Turn off
	readDataFromBlock while reading via GetField.
	(GetField$1.get(String, Object)): Pass Class of default value to
	getField.
	(getField): Allow for null default values.

	* java/io/ObjectOutputStream.java: Fixed typo in comment.
	(PutField$1.put): Fixed calls of checkType in most of the put
	methods to pass the correct parameter.
	(PutField$1.put(String, Object)): Allow for null value arg.
	(PutField$1.write): Turn off writeDataAsBlocks while writing via
	PutField.

	* java/io/ObjectStreamClass.java (serialPersistentFields): Fixed
	typo in spec'ed field name.
	(getSerialPersistentFields): Changed spelling of method to match
	the correct spelling of the spec'ed field name.

More serialization fixes per Mauve errors.
