policy: don't track roam_scan_done
Don't determine a finished client scan based on whether the current node
has seen a beacon or not.
This works surprisingly bad on 5 GHz nodes, as clients may refuse to
perform active scanning on this frequency band. In case the clients does
refuse to scan the 5 GHz band but scans the 2.4 GHz band actively, we
might have a good indication about a better node on this band at least.
However, as the roam state-machine requires to have seen a probe request
from the client to direct him to a better node, thi process will not
continue, which either ends the node in being kicked due to exceeding
the number of max tries or the scan cooldown to kick in.
The solution to this is fairly simple: Don't track the roam_scan_done
state but instead just determine a better candidate after the scan
interval finished.
To ensure the indicated signal levels are as recent as 2 *
scan-interval, add a max_age parameter to find_better_candidate.

local-node: don't read pointer after clear
The name pointer provided by ubus get's cleared after the first call to
ubus_register_subscriber in usteer_get_node. The leads to an incorrect
ifindex returned by if_nametoindex due to the 0 characters long string.
Work around this issue by reusing the interface name already stored in
the local node struct.
Fixes querying the wrong interface with netlink, resulting in incorrect
SSIDs used for the nodes.

usteer: add support for IPv6 remote exchange
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.
