[ospfd] NSSA translate-enabled ABR should declare itself as ASBR

	* ospf_abr.c: (general) NSSA translate-candidate ABRs need to
	  be ASBRs, or other routers may rightfully refuse to install
	  translated type-5s LSAs. reported by dendroot@gmail.com.
	  (ospf_abr_nssa_check_status) Detect change in translator
	  state when ABR, and inc/dec redistribute count as when we
	  leave/enter the disabled state - so that translate-enabled
	  ABR properly sets ASBR bit on non-NSSA areas.
	  Run the resulting function through indent to clean it up.
	* ospf_lsa.c: (router_lsa_flags) For purposes of ASBR bit,
	  NSSA area is same as stub area.
