f3e5917850 Enables multihop mode for IBGP by default.
This is more consistent with common usage and also with the behavior of
other implementations (Cisco, Juniper).

Also changes the default for gw mode to be based solely on
direct/multihop.

b21955e058 Fixes a bug related to mixed up neighbor events in BGP.
Neighbor events related to received route next hops got mixed up with
sticky neighbor node for an IP of the BGP peer. If a neighbor for a next
hop disappears, BGP session is shut down.

send notification packet to close the session.

79b4e12e60 Implements interface masks for choosing router id.
Router ID could be automatically determined based of subset of
ifaces/addresses specified by 'router id from' option. The patch also
does some minor changes related to router ID reconfiguration.

Thanks to Alexander V. Chernikov for most of the work.

cf98be7b67 Allows rejected routes to be kept and examined.
When 'import keep rejected' protocol option is activated, routes
rejected by the import filter are kept in the routing table, but they
are hidden and not propagated to other protocols. It is possible to
examine them using 'show route rejected'.

c0adf7e9fc Better support for multitable protocols.
The nest-protocol interaction is changed to better handle multitable
protocols. Multitable protocols now declare that by 'multitable' field,
which tells nest that a protocol handles things related to proto-rtable
interaction (table locking, announce hook adding, reconfiguration of
filters) itself.

Filters and stats are moved to announce hooks, a protocol could have
different filters and stats to different tables.

The patch is based on one from Alexander V. Chernikov, thanks.
