In order to send passive beacon-requests, channel and op-class of nodes
are required. Obtain this information per local-node from hostapd.

Make usteer handle incoming BSS-transition requests. Update with the
most active roaming neighbors like we already do for imminent
disassociations.
Create a new ubus method which calls hostapds bss_transition_request
method. This does not set the disassoc imminent bit, thus will not
automatically disassoc the requesting STA.

Logic for handling STA transition to disconnected state is
present multiple times. Create a new method to remove
duplicate code.

Move the sta frequency-seen logic to usteer_sta_info_update.
This method is called on every occurence the seen frequency
is set now, thus removing the duplicate code.

Move the roam event counters to a dedicated struct.
Update the ubus output to represent this new organization.

Save the RRM capabilities of STAs when updating clients from hostapd.
This is required to determine which measurement modes a STA supports.

Save the timestamp of the node creation. This is required to optimize
the selection of most-roamed to neighbors relative to their creation
time.

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.

Add a last_connected field to the sta_info struct. This field can be
used to determine, if and when a client was last connected to a given
node. This way, other nodes can determine where a client roamed to or
from.

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.

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.
