bgpd: implement "next-hop-self all"

As specified in:
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/command/irg-cr-book/bgp-m1.html#wp4972925610

This allows overriding next-hop for ibgp learned routes on an
RR for reflected routes.

Especially useful for using iBGP in DMVPN setups. See:
