Subject: Makefile.am: Add HashSet.java and java/lang/ref classes.

	* Makefile.am: Add HashSet.java and java/lang/ref classes.
	Remove BasicMapEntry.java and Bucket.java.
	* Makefile.in: Rebuilt.
	* java/util/HashMap.java: Rewritten.
	* java/util/HashSet.java: Imported from classpath.
	* java/util/WeakHashMap.java: Imported from classpath.
	* java/util/Hashtable.java: Rewritten based on new HashMap code.
	* java/util/Bucket.java: Deleted.
	* java/util/BasicMapEntry.java: Deleted.
	* java/util/Collections.java (search): Use a for-loop, not iterator
	hasNext().
	(copy): Use a for-loop. Throw an IndexOutOfBoundsException if run out
	of elements in source.
	(max): Use a for-loop.
	(min): Ditto.
	(reverse): Keep track of positions instead of using Iterator's
	nextIndex() and previousIndex().
	(shuffle(List)): Initialize defaultRandom if required using
	double-check thread safety idiom. Call two-argument shuffle method
	using defaultRandom.
	(defaultRandom): New field.
	(shuffle(List, Random)): Use a for-loop. Keep track of pos instead
	of using previousIndex() and nextIndex().
	(singletonMap(iterator)): Use a HashMap.Entry, not BasicMapEntry.
	* java/util/AbstractCollection.java (toString): Use a StringBuffer.
	* java/util/AbstractMap.java (toString): Use StringBuffer.
	* java/lang/ref/PhantomReference.java: Imported from classpath.
	* java/lang/ref/SoftReference.java: Ditto.
	* java/lang/ref/Reference.java: Ditto.
	* java/lang/ref/WeakReference.java: Ditto.
	* java/lang/ref/ReferenceQueue.java: Ditto.
