Add an optional timeout when a better roaming candidate is not found
after the scan-retry limit. The roam state-machine will not retry
scanning before this timeout has expired.
If the timeout is set to 0, the client is kicked instead, which
resembles the behavior prior this commit.
This is added, as without this patch, if a forced disconnect
is not desired before roam_scan_trigger is exceeded the client will
repeatedly be asked to return active beacon-reports. For battery powered
clients this can result in a noticeable battery drain.

Prioritize neighbor candidates installed to hostapd. Add a new config
option to set a limit for neighbor reports installed to hostapd. This is
due to the fact, most devices will only evaluate a certain amount of
neighbor reports. Furthermore, the number of neighbor reports possible
is limited by the maximum frame size.

Keep track of STA journeys between multiple nodes. When a new STA is
reported from a foreign node, check whether this STA was previously
associated with a local node.
Vice versa, check upon association whether or not the STA was previously
associated with a foreign node.
Keep track of these roaming transactions using two new (local) fields of
the node struct.

This adds optional support for message exchange using IPv6 multicast
messaging. This has the ability for routers and switches between nodes
to route traffic between usteer nodes multicast-aware.
By default, IPv4 is used. IPv6 can be enabled by configuring the ipv6
option to 1.
