rpm: reload dbus in wicked-service post-install (bnc#897775)

We install dbus security policies for wicked service -- ensure
we tell dbus to (re)load them after installation / uninstall.
rpm: dbus policies as noreplace config (bnc#897775)

We still mark the policies as config to keep backups, but
replace them on upgrade to ensure they match new daemons.
man: added startmode hotplug and use-nanny (bnc#896403)

fsm: Add timeout to the ni_fsm_wait_tentative_addrs()
config: improved allowed update mask/defaults

DHCPv6 protocol does not define routing options (-> RA),
current linux ypbind does not support ipv6, ... do not
confuse users showing the current config would do this.

fsm: introduce timeout for tentative addresses loop
client-state: Do not fail on parsing empty origin and uuid
ifstatus: correctly OR grouped leas status (bnc#896188)
fsm: no failure report on failed lease (bnc#896188)

It is not a fsm failure when some lease request fails
or has been deferred -- ifup/ifstatus shows the final
status at the end.
hwaddr: added is_invalid and broadcast utilities (bnc#898622)
hwaddr: change hwaddr only when valid (bnc#898622)
