mauve-libgcj: Activated serialization tests.

* mauve-libgcj: Activated serialization tests.
	* gcj/field.h (getModifiers): Mask off unknown flags.
	* gnu/java/security/provider/SHA.java (munch): Reset buffer to 0 so
	spurious bits don't cause discrepancies.
	* java/io/ObjectOutputStream.java: Fixed typo in comment.
	* java/io/ObjectStreamClass.java: Fixed typos in comments.
	(lookup): Applied patch from Brian Jones <cbj@gnu.org> to optimize.
	(hasClassInitializer): Call getDeclaredMethod instead of getMethod.
	* java/lang/Throwable.java (serialVersionUID): New field.
	* java/lang/reflect/Modifier.java (ALL_FLAGS): Preserve STRICT if used.
	* java/lang/reflect/natConstructor.cc (getModifiers): Mask off
	unknown flags.
	* java/lang/reflect/natMethod.cc: Ditto.
