ByteBuffer.java (shiftDown): New helper method.
* 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.
