* (general) Bug #234, see also [quagga-dev 3902].
Fix problem with nbr_self not being properly reinitialised
when an interface comes up, after having been down.
+ Some re-arrangement done by Paul Jakma, any bugs introduced
+ on top of Len's suggested changes are his.
* ospf_neighbor.c: (ospf_nbr_add_self) centralise
