Parse unknown enum values like full proto2.

Store unknown values in the unknown field set. For repeated fields,
store unknown values while leaving known values in place.

This can lead to some strange behaviors, such as new values not being
serialized (because the unknown field set copy comes second on the
wire), or the order of repeated fields changing (if the value is
serialized when the field is unknown, and deserialized later when it
becomes known). Having strange behavior be consistent with the
standard implementation is nonetheless better than diverging.
