Add generic types.

2010-04-28  Andrew John Hughes  <ahughes@redhat.com>

	* gnu/javax/print/ipp/IppUtilities.java:
	(INTEGER_CLASS_ARRAY): Use generic typing.
	(TEXT_CLASS_ARRAY): Likewise.
	(classesByName): Likewise.
	(instanceByClass): Likewise.
	(getClass(String)): Remove cast.  Return generic type.
	(getSupportedAttrName(Class<? extends Attribute>)): Remove cast.
	Add generic type to parameter.
	(getSupportedCategory(Class<?> extends Attribute>)): Likewise.
	(getEnumAttribute(String,Object)): Add missing generic types on Class.
	(getIntegerAttribute(String,int)): Likewise and on Constructor.
	(getTextAttribute(String,byte,byte[])): Likewise.
