When checking whether a client is allowed to associate to a node, the
lower ceiling for kicking clients was not taken into account when
assoc-steering is disabled.
The problem behind this is, that a configured lower barrier for
disassociating clients (kicking) would kick the client immediatly after
association. In the worst scenario the client immediatly associates
again to the station and ends up in a kick loop.
Don't allow associating when a min_snr is configured and the client
signal is below this value.

Make the connection state of a sta-info more readable by introducing an
enum for the STA connection state.
Also switch come comparison cases to use the explicit enum values to
make the code more readable.

Add the node BSSID to messages exchanged between usteer hosts. This way,
a foreign node can determine the node reported by a STA using beacon
reports.

Add the node BSSID to the usteer_node struct. This will be helpful in
the future when evaluating beacon reports from STAs.

The host address is allocated on the heap, hence it has to be freed when
freeing the containing struct.

When checking if the hostaddresses match up, the result returned from
strcmp was incorrectly evaluated. strcmp returns 0 in case both strings
match.

Add a build dependency for libpcap, as it is required for the monitor
utility but not usteer itself. Use a build-dependency, as the monitor
utility executable is not packaged.

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.

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.
