[0/7] Assorted rhashtables cleanups.

Following 7 patches are selections from a recent RFC series I posted
that have all received suitable Acks.

The most visible changes are that rhashtable-types.h is now preferred
for inclusion in include/linux/*.h rather than rhashtable.h, and
that the full hash is used - no bits a reserved for a NULLS pointer.

Thanks,
NeilBrown
