ByteBuffer.java (shiftDown): New helper method.

Browse source 
* java/nio/ByteBuffer.java (shiftDown):  New helper method.
	* java/nio/natDirectByteBufferImpl.cc (shiftDown):  New implementation.
	* java/nio/ByteBufferImpl.java (compact):  Use new shiftDown method.
	* sava/nio/ByteBufferHelper.java:  Remove redundant 'final' specifiers.
	Pass ByteOrder parameter to most methods, since the underlying
	ByteBuffer's order isn't always what we should use.
	* java/nio/ByteBufferImpl.java:  Pass byte-order various places.
	* java/nio/DirectByteBufferImpl.java:  Likewise.
	Use ByteBufferHelper methods.
	* java/nio/MappedByteBufferImpl.java:  Likewise.
	(compact):  Use shiftDown.
	* java/nio/CharViewBufferImpl.java (<init>):  Pass byte-order.
	(get, put):  Use ByteBufferHelper.
	(compact):  Use new shiftDown method.
	(duplicate(boolean)):  New helper method.
	(duplicate, asReadOnlyBuffer):  Use it.
	(order):  Return endian field.
	* java/nio/DoubleViewBufferImpl.java:  Likewise.
	* java/nio/FloatViewBufferImpl.java:  Likewise.
	* java/nio/IntViewBufferImpl.java:  Likewise.
	* java/nio/LongViewBufferImpl.java:  Likewise.
	* java/nio/ShortViewBufferImpl.java:  Likewise.
	* java/nio/CharViewBufferImpl.java (subsequence):  Redundant test.
	* java/nio/DirectByteBufferImpl.java (shiftDown):  New native method.
	(compact):  Re-implement using shiftDown.
