Subject: [vty] Add support for a 'restricted mode' with anonymous vty
connections
* lib/command.h: Add a RESTRICTED_NODE, intended for use with
anonymous, 'no login' vtys, to provide a subset of 'view' mode
commands.
* lib/command.c: Add RESTRICTED_NODE bits, nothing special, just
following VIEW_NODE.
* lib/vty.c: (vty_auth) enable authentication should fall back to
restricted/view node as appropriate.
(vty_create) init vty's to restricted/view node as appropriate,
for the 'no login' case.
(vty_{no_,}restricted_mode_cmd) config commands to enable
'anonymous restricted' in vty configuration.
(vty_config_write) 'anonymous restricted' config.
(vty_init) Install some commands to restricted mode, and the
'anonymous restricted' config commands into VTY_NODE.
* bgpd/*.c: Install some of the safe(r) BGP commands into
'restricted mode', i.e. lookup commands of non-sensitive data.
Useful with looking-glass route-servers.
