If IP_MULTICAST_LOOP is left to true/1 the dawn instance will send the packet out and then receive it itself, this will generate a 'Remote PROBE updated client / BSSID = XX:XX:XX:XX:XX:XX / YY:YY:YY:YY:YY:YY' after every 'Local PROBE used to update client / BSSID = XX:XX:XX:XX:XX:XX / YY:YY:YY:YY:YY:YY'
Rename function `ubus_add_oject` -> `ubus_add_dawn_object` to avoid
confusion and potential collision with function `add_ubus_object` from
libubus.

This also fix a typo error on check_timeout on wrong list
Fixes: 47e98ef ("network: ping pong keepalive for tcp connections")
Signed-off-by: Chen Minqiang <ptpt52@gmail.com>
For an unknown reason the entry that is returned in ap_array_unlink_entry
was always set to NULL. This commit changes the function so it returns the
ap that should be unlinked. This is needed to free the corresponding
memory that is allocated by the ap struct.
Thanks a lot to ptpt52 for reporting this issue.

Somtimes client connetions will not close therfore add a timeout. Add a
new timer that checks every 5s if we did not receive anything from a
client for (default) 60s. Can be configured via client_timeout.
Code is based on the work of ptpt52.

In the build_hearing_map_sort_client there was a dawn_mutex_require
without having locked the mutex resulting in warnings:
daemon.warn dawn: MUTEX require = 4226B8@ubus.c:2003[2012069248l] - appears to be UNLOCKED!
daemon.warn dawn: MUTEX require = 4226B8@datastorage.c:694[2012069248l] - appears to be UNLOCKED!
I guess it was a typo, because before entering the
client_array_get_client function the mutex client_array_mutex needs to
be locked and not required.

Modifications to BEACON and PROBE handling to improve understanding of
RSSI and RCPI / RSNI values. Also address bugs in frequency / band handling.
[cleanup commit message]
Signed-off-by: Nick Hainke <vincent@systemli.org>
Updated approach to sending BEACON REQUEST. Each AP asks every 802.11k
enabled client for the BEACON REPORT of a single other AP in the network
at N second intervals, where N is the refresh period / num-APs. N seconds
later the request is sent for the next AP.

In addition to scored "hard" kick for all clients (inc. legacy), add a "soft"
kick for 802.11v aware clients by always asking them to move if below
threshold RSSI, but with no mandatory disassociation.
