ospfd: Extend 'ip ospf area' to take address argument + rationalise ospf enable

* ospfd.c: (general) Clean up the whole running of OSPF on interfaces.
  (add_ospf_interface) taking (struct interface *) arg is pointless here.
  (ospf_is_ready) new helper.
  (ospf_network_run_subnet) Put all the code for choosing whether to enable
  OSPF on a subnet, and if so which area configuration to use, here. If a
  subnet should not be enabled, ensure an existing oi is freed.
  (ospf_network_run_interface) Just call run_subnet for all subnets on an
  interface.
  (ospf_network_run) Just call run_interface for all interfaces.
  (ospf_if_update) Just call run_interface for the given interface.
  (ospf_network_unset) Just call run_subnet for existing ois.
  (ospf_update_interface_area) helper: update area on an oi, or create it.
  (ospf_interface_set) renamed to ospf_interface_area_set for clarity.
  Ensures OSPF is created, then into if_update.
  (ospf_interface_unset) renamed to ospf_interface_area_unset and collapses
  down to simple loop to call run_subnet for all ois.
* ospf_interface.h: add a more general OSPF_IF_PARAM_IS_SET, which does the
  right thing and takes default config into account.
* ospf_vty.c: (OSPF_VTY_GET_IF_PARAMS) new macro with common code for handling
  interface parameter commands - only used for 'ip ospf area' in this commit.
  (OSPF_VTY_PARAM_UNSET) similar
  ({no,}ip_ospf_area) Use said macros.
* doc/ospfd.texi: add 'ip ospf area' command.
