	(putInt): Use limit() instead of limit.
	* gnu/java/nio/CharBufferImpl.java
	(slice): Fixed implementation.
	(subSequence): Better bounds checking.
	* gnu/java/nio/MappedByteFileBuffer.java:
	Import all needed classes directly.
	* java/nio/ByteBuffer.java
	(hashCode): New dummy method.
	* java/nio/CharBuffer.java
	(array_offset): New member variable.
