fsm: Increase get matching workers verbosity (bnc#882311, bnc#885040)
ifreload: build hierarchy before starting workers
ifreload: Increase verbosity (bnc#882311, bnc#885040)
ifreload: Reset matching workers before ifup check
fsm: Use valid origin (workers name or location)

There is no xml location specified for <device> nodes.
fsm: Hide configuration failed msg for build hierarchy
ifstatus: moved device-ready flag to ifflags

This causes that the device-ready is directly visible via
dbus (in client and nanny) in every refresh and does not
need additional tweaks to handle it.
Correctly set ipv4 and ipv6 enabled flags.

When an the flag is currently disabled in the system (e.g.
by an old config), a new config (ifup) has to explicitly
enable it and not keep unchanged (send a disable only).
fsm: tune ni_ifworker_by_ifindex

- rename to ni_fsm_ifworker_by_ifindex
- add param validity check
fsm: Add object_path parsing functions

- __ni_fsm_dbus_objectpath_to_ifindex
- __ni_fsm_dbus_objectpath_to_name
fsm: tune ni_fsm_ifworker_by_object_path

This function looks also for not refreshed
workers by their name.
Revert "server: no unrequested device-ready events (bnc#871135)"

fsm: wait for existing configration workers (bnc#876855, bnc#880515)

When interface shows up late (but the configuration is present)
we wait for it until WAIT_FOR_INTERFACES timeout.
