netif: more ip6 state changes invoke status callback

Browse Source 
For applications that use NETIF_STATUS_CALLBACK to help keep track of
extra per-address shadow state of IPv6 addresses, even in the light of
autogenerated addresses (which may "spontaneously" appear/disappear),
state transitions between tentative, duplicated, and invalid are
important as well. Therefore, invoke the status callback for all such
state transitions. Continue to filter out state changes between
various levels of progress of the tentative state, though.
