	* java/lang/Class.java: Fix forName() declaration.
	(getPackage): New method based on Classpath implementation.
	(getProtectionDomain0): New native method decl.
	(getProtectionDomain): New method.
	* java/lang/ClassLoader.java (getParent): Now final.
	(definedPackages): New field.
	(getPackage): New.
	(defineClass): New variant with protectionDomain argument.
	(definePackage): New.
	(getPackages): New.
	(findSystemClass): Now final.
	(getSystemResourceAsStream): Remove redundant "final" modifier.
	(getSystemResource): Remove redundant "final" modifier.
	(getResources): Now final.
	(protectionDomainPermission): New static field.
	(unknownProtectionDomain): Ditto.
	(defaultProtectionDomain): Ditto.
	(getSystemClassLoader): Now non-native.
	* java/util/ResourceBundle.java (tryGetSomeBundle): Use the correct
	arguments for Class.forName().
	* java/lang/Package.java: New file.
	* gnu/gcj/runtime/VMClassLoader.java (getVMClassLoader): Removed.
	(instance): Static initialize singleton.
	(findClass): Override this, not findSystemClass.
	* java/lang/natClassLoader.cc (defineClass0): Set class's
	protectionDomain field as specified.
	(getSystemClassLoader): Removed.
	(findClass): Renamed from findSystemClass. Call the interpreter via
	URLClassLoader.findClass if loading class via dlopen fails.

/**
* This class models a group of Java permissions. It has convenient
* methods for determining whether or not a given permission is implied
* by any of the permissions in this collection.
* <p>
* Some care must be taken in storing permissions. First, a collection of
* the appropriate type must be created. This is done by calling the
* <code>newPermissionCollection</code> method on an object of the
* permission class you wish to add to the collection. If this method
* returns <code>null</code>, any type of <code>PermissionCollection</code>
* can be used to store permissions of that type. However, if a
* <code>PermissionCollection</code> collection object is returned, that
* type must be used.
* <p>
* The <code>PermissionCollection</code>'s returned
* by the <code>newPermissionCollection</code> instance in a subclass of
* <code>Permission</code> is a homogeneous collection. It only will
* hold permissions of one specified type - instances of the class that
* created it. Not all <code>PermissionCollection</code> subclasses
* have to hold permissions of only one type however. For example,
* the <code>Permissions</code> class holds permissions of many types.
* <p>
* Since the <code>newPermissionCollection</code> in <code>Permission</code>
* itself returns <code>null</code>, by default a permission can be stored
* in any type of collection unless it overrides that method to create its
* own collection type.
