The CMD_PORT_AUTHORIZED event was described as an event which indicated
a successfully completed 4-way handshake. But the behavior was
not as advertized. The only driver which uses this is brcmfmac, and
this driver only sends the event after a successful 802.1X-FT roam.
This prevents userspace applications from knowing if the 4-way completed
on:
1. Normal 802.1X connects
2. Normal PSK connections
3. FT-PSK roams
wpa_supplicant handles this incorrect behavior by just completing
the connection after association, before the 4-way has completed.
If the 4-way ends up failing it disconnects at that point.
Since this behavior appears to be expected (wpa_s handles it this
way) I have changed the wording in the API description to reflect the
actual behavior.

Some usable channels are located in the union of adjacent
regulatory rules, for example channel 144 in Germany.
Enable them, by also checking if a channel spans two adjacent
regulatory rules/frequency ranges.
All flags involved are disabling things, therefore we can build
the maximum by or-ing them together. Furthermore, take the maximum
of DFS CAC time values and the minimum of allowed power of both
adjacent channels in order to comply with both regulatory rules at
the same time.

Each nexthop group contains an indication if it has IPv4 nexthops
('has_v4'). Its purpose is to prevent IPv6 routes from using groups with
IPv4 nexthops.
However, the indication is not updated when a nexthop is replaced. This
results in the kernel wrongly rejecting IPv6 routes from pointing to
groups that only contain IPv6 nexthops. Example:
# ip nexthop replace id 1 via 192.0.2.2 dev dummy10
# ip nexthop replace id 10 group 1
# ip nexthop replace id 1 via 2001:db8:1::2 dev dummy10
# ip route replace 2001:db8:10::/64 nhid 10
Error: IPv6 routes can not use an IPv4 nexthop.
Solve this by iterating over all the nexthop groups that the replaced
nexthop is a member of and potentially update their IPv4 indication
according to the new set of member nexthops.
Avoid wasting cycles by only performing the update in case an IPv4
nexthop is replaced by an IPv6 nexthop.
