Implements 'next hop keep' option for BGP.
...
This option allows to keep the received next hop even in cases when
the route is sent to an interface with a different subnet.

Implements ADD-PATH extension for BGP.
...
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

Process well-known communities before the export filter (old behavior is
to process these attributes after, which does not allow to send route
with such community) and just for routes received from other BGP
protocols. Also fixes a bug in next_hop check.
