bgpd: Move 'enforce-first-as' from global to peer
This commit moves the command 'bgp enforce-first-as' from global BGP
instance configuration to peer/neighbor configuration, which can now be
changed by executing '[no] neighbor <neighbor> enforce-first-as'.
End users can now enforce sane first-AS checking on regular sessions
while e.g. disabling the checks on routeserver sessions, which usually
strip away their own AS number from the path.
To ensure backwards-compatibility, a migration routine was added which
automatically sets the 'enforce-first-as' flag on all configured
neighbors if the old global setting was activated. The old global
command immediately disappears after running the migration routine once.
