I don't really feel too strongly about this, but it seems to me that
there is a difference between the checkers and prioritizers, which
it seems like most users of libmultipath would want, and the foreign
code, which doesn't seem that way. libmpathpersist, for instance,
will use the checkers and prioritizers, but not the foreign code.
On the other hand, if the caller isn't using the foreign code,
then grabbing the lock and checking the foreign pointer shouldn't
take much time.
