Support for self originated AS-external LSA.
With "redistribute (static|connected|default|none)" it is possible to
tell ospfd which external routes should be announced.
Connected routes will be announced only if there is no corresponding
interface configured, in that case the prefix is not external.
Adding and removing of announced prefixes are done automaticaly.
