Reverting c/s 20158 does not remove drbd support in xen.  On the
contrary, it fixes the use of drbd as documented here

http://www.drbd.org/users-guide/s-xen-configure-domu.html

The drbd project provides block-drbd.  I'm not talking about removing
it.  I'm talking about removing a hack in xend that prevents even using
drbd resource type.
