* java/nio/DirectByteBufferImpl.java
(shiftDown): Made static, give address as argument and
provide a convenience method that overwrites shiftDown in
ByteBufferImpl and calls the native shiftDown.
* java/nio/MappedByteBufferImpl.java
(): Use optimized method in DirectByteBufferImpl.
* java/nio/natDirectByteBufferImpl.cc
(shiftDown): Changed method signature. Removed usage of array_offset.
