Automatically create a default lo(4) interface per rdomain.
In order to stop abusing lo0 for all rdomains, a new loopback interface
will be created every time a rdomain is created. The unit number will
be the same as the rdomain, i.e. lo1 will be attached to rdomain 1.
If this loopback interface is already in use it wont be possible to create
the corresponding rdomain.
In order to know which lo(4) interface is attached to a rdomain, its index
is stored in the rtable/rdomain map.
This is a long overdue since the introduction of rtable/rdomain. It also
fixes a recent regression due to resetting the rdomain of an incoming
packet reported by semarie@, Andreas Bartelt and Nils Frohberg.
