With Destination struct, multiple Paths can be moved from the table package to the server package in a cleaner way; for features such as add-path. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2017-07-04server: split rib into twoFUJITA Tomonori
currently, route server peers and non route server peers use the single global rib. To support deterministic-med for non route server peers, this splits the rib into two; easier to handle the best path selection in different ways. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2017-06-16config: Use State to get NeighborAddress instead of ConfigSatoshi Fujimoto
By introducing dynamic neighbor feature, GoBGP can have dynamic neighbors, and corresponding Config.NeighboAddress can be empty. This patch sets State.NeighborAddress for all neighbors, and gets the neighbor's address from them. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>

2017-06-05*: Support Peer-Group ConfigurationSatoshi Fujimoto
This patch enables to create peer-groups, also supports dynamic configuration to peer-groups. Manually set fields in neighbor configs have priority over its peer-group's config, except some fields, like "peer-as", or "minimum-advertisement-interval" and so on.

2017-06-03server: Implement event for BGP message watcherIWASE Yusuke
This patch enables to watch events for monitoring received BGP messages before the state comparison. Note: Currently, this event nortifies UPDATE message only, because the other messages will be handled in FSMHandler and not received at BgpServer, so BgpServer cannot send event for these messages.

2017-05-09server: ignore routes when local AS is in AS_PATHISHIDA Wataru
RFC4271 9.1.2 Phase 2: Route Selection If the AS_PATH attribute of a BGP route contains an AS loop, the BGP route should be excluded from the Phase 2 decision function. AS loop detection is done by scanning the full AS path (as specified in the AS_PATH attribute), and checking that the autonomous system number of the local system does not appear in the AS path. Operations of a BGP speaker that is configured to accept routes with its own autonomous system number in the AS path are outside the scope of this document. Also this commit adds support for allow-own-as option to relax this. Signed-off-by: ISHIDA Wataru <ishida.wataru@lab.ntt.co.jp>

2017-04-18policy: send a withdrawal if export policy blocks an existing routeISHIDA Wataru
This patch fixes a bug of export policy and implicit withdrawal. When a path is filtered by export policy, we need to check whether the old path (implicit withdrawn path) was sent before the new path. If it has been sent, we need to send a withdrawal message.
