Remove unused arguments from dom_rtattach/dom_rtdetach functions and make them return/accept 'struct rib_head' instead of 'void **'. Declare inet/inet6 implementations in the relevant _var.h headers similar to domifattach / domifdetach. Add rib_subscribe_internal() function to accept subscriptions to the rnh directly.
