StringBuffer.java (ensureCapacity): Don't resize vector when shared.

Browse Source 
* java/lang/StringBuffer.java (ensureCapacity): Don't resize
	vector when shared.
	* java/util/Locale.java (Locale(String,String)): Implement in
	terms of 3-argument version; variant now defaults to empty
	string.
	(toString): Assume variant is not null.
	(equals): Assume all strings are not null.
	(Locale): Throw NullPointerException if any argument is null.
	* java/util/ResourceBundle.java (getBundle): Don't try the base
	name; now implicit in partialGetBundle call.
	(trySomeGetBundle): Search for parent bundles and call setParent
	as required.
	(partialGetBundle): Added `langStop' argument.  Use
	`Locale.toString' to compute bundleName.
	(resource_cache): New static field.
	(partialGetBundle): Cache the returned resource bundle.  Now
	synchronized.
	* gnu/gcj/text/LocaleData_en.java (contents): [collatorRule] Added
	missing `<'.
	* mauve-libgcj: Enable Collator and RuleBasedCollator.
	* java/text/natCollator.cc (decomposeCharacter): `base' now
	`const'.
	* Makefile.in: Rebuilt.
	* Makefile.am (ordinary_java_source_files): Added
	CollationElementIterator, CollationKey, Collator,
	RuleBasedCollator.
	(nat_source_files): Added natCollator.cc.
	* java/text/RuleBasedCollator.java (ceiNext): No longer static.
	(compare): Pass `this' to CollationElementIterator constructor.
	(getCollationElementIterator): Likewise.
	(ceiNext): Fix off-by-one error when finding initial substring.
	(next): Correctly mask off bits when computing return value.
	Fixed return values when one string is shorter than the other.
	* java/text/CollationElementIterator.java (collator): New field.
	(CollationElementIterator): Added collator argument.
	(next): Call ceiNext on collator object.
