* bgp_packet.c: (bgp_open_receive) fix warning in a zlog call
* bgp_vty.c: (bgp_vty_return) add return code
* bgpd.c: (bgp_master_init) setup the socket list.
* bgp_network.c: Remove the dual IPv4/6 socket thing for now, which
was implemented by Michael, until such time as its clear its
required for Linux (see sockopt comments). IPv6 support, including
IPv4 sessions on AF_INET6 sockets, therefore is broken, and the
'-l 0.0.0.0' arguments would need to be given to bgpd to make
things work here.

* bgp_network.c: (bgp_md5_set_one) shim between libzebra tcp-md5
sockopt and bgpd.
(bgp_md5_set_socket) Helper for bgp_connect
(bgp_md5_set) setup TCP-MD5SIG for the given peer.
(bgp_connect) call out to bgp_md5_set_socket for the outgoing
connect socket.
(bgp_socket) save references to the listen sockets, needed if
TCP-MD5SIG is applied later or changed.
* bgp_vty.c: (*neighbor_password_cmd) New 'neighbor ... password'
commands.
* bgpd.c: (peer_{new,delete) manage TCP-MD5 password
(peer_group2peer_config_copy) inherit TCP-MD5 password
(peer_password_{un,}set) orchestrate the whole add/remove of TCP-MD5
passwords: applying checks, stopping peers, and trying to return
errors to UI, etc.
(bgp_config_write_peer) save password.
Fix missing newline in writeout of neighbor ... port.

* sockunion.c: ifdef out various places that converted
