fsm inetable: sync mesh iface w/ uci, use batctl gw off, reduce redundancy

- add mesh_add/del_ipv4 to set/unset IPv4 addresses of mesh iface; the
  address is set using ifconfig to avoid ifudown+ifup but also updated
  in UCI to maintain a consistent state
- use this function in queen, ghost and robinson state transitions
- use `batctl gw off` in robinson state: this allows to deliever local
  DHCP replies while dropping the idea of announcing fake gateways
- ghost.leave reuses queen.leave
