* java/nio/MappedByteBuffer.java: (forceImpl, isLoadedImpl, loadImpl,
unmapImpl): New dummy methods, to be overridden by subclass.
(finalize, isLoaded, load, force): New methods.
* java/nio/MappedByteBufferImpl.java: More-or-less rewrite.
Now works, at least for read mapping.

inherit it.
* java/nio/ByteBuffer.java (endian): Make non-private so other
java.nio classes can inherit it.
(<init>): Don't bother clearing array_offset.
* java/nio/ByteBuffer.java (allocate): Re-implement using wrap.
* java/nio/ByteBuffer.java (get(byte[],int,int)): Check underflow.
Remove redundant test.
* java/nio/ByteBufferImpl.java (asCharBuffer, asShortBuffer,
asIntBuffer, asLongBuffer, asFloatBuffer, asDoubleBuffer):
Use new XxxViewBufferImpl constructors.
* java/nio/MappedByteBufferImpl.java: Likewise.

(offset): Remove unused field.
(<init>): Modify one and add another constructor. Change callers.
(allocateDirect): Removed - not used.
(getImpl, putImpl): Make static and pass address explicitly,
to make them useful for MappedByteBufferImpl.
(get, put): Check for underflow. Modify for new getImpl.
(getImpl): New native method where target is array.
(get(byte[],int,int)): Use the above.
(adjustAddress): New static native method.
