	PR libgcj/18115
	* java/nio/Buffer.java (address): New field.
	* java/nio/DirectByteBufferImpl.java (address): Removed.
	* java/nio/MappedByteBufferImpl.java (address): Likewise.
	* java/nio/CharViewBufferImpl.java (CharViewBufferImpl):
	Explicitly initialize Buffer.address if needed.
	* java/nio/DoubleViewBufferImpl.java (DoubleViewBufferImpl): Likewise.
	* java/nio/FloatViewBufferImpl.java (FloatViewBufferImpl): Likewise.
	* java/nio/IntViewBufferImpl.java (IntViewBufferImpl): Likewise.
	* java/nio/LongViewBufferImpl.java (LongViewBufferImpl): Likewise.
	* java/nio/ShortViewBufferImpl.java (ShortViewBufferImpl): Likewise.
	* jni.cc (_Jv_JNI_GetDirectBufferAddress): Don't assume buffer is a
	DirectByteBufferImpl object.
	(_Jv_JNI_GetDirectBufferCapacity): Likewise.
	* testsuite/libjava.jni/directbuffer.c,
	testsuite/libjava.jni/directbuffer.java,
	testsuite/libjava.jni/directbuffer.out,
	testsuite/libjava.jni/bytebuffer.c,
	testsuite/libjava.jni/bytebuffer.java,
	testsuite/libjava.jni/bytebuffer.out: New files.
