It could have been possible to get into an endless loop of retried EAP
authentication followed by failing or not completed 4-way handshake if
there was a different interpretation of EAP authentication result
(success on AP, failure on STA). Avoid this by limiting the number of
consecutive EAPOL reauth attempts without completing the following 4-way
handshake.

Unsolicited broadcast Probe Response frame configuration did not work in
hostapd due fils_discovery_min_int being used by mistake where
fils_discovery_max_int should have been used in checking for conflicting
configuration. The latter is the one used to decide whether FILS
discovery is enabled or not.

This is a workaround for mac80211 behavior of retransmitting the
Association Request frames multiple times if the link layer retries
(i.e., seq# remains same) fail. The mac80211 initiated retransmission
will use a different seq# and as such, will go through duplicate
detection. If we were to change our DH key for that attempt, there would
be two different DH shared secrets and the STA would likely select the
wrong one.

Add an alternative sequence for performing the RADIUS ACL check and PSK
fetch. The previously used (macaddr_acl=2, wpa_psk_radius=2) combination
does this during IEEE 802.11 Authentication frame exchange while the new
option (wpa_psk_radius=3) does this during the 4-way handshake. This
allows some more information to be provided to the RADIUS authentication
server.

While these do not return error code within the current hostapd
implementation, matching functions in wpa_supplicant AP functionality
will have an error case and using consistent return type will make the
control interface code more consistent.
In addition, export hostapd_set_acl() in preparation for the
wpa_supplicant control interface implementation extension.

Only the SME-in-hostapd case updated sta->ext_capability while the
SME-in-the-driver case updated sta->qos_map_enabled, but not other items

There can be some discrepancy between the theorical dfs cac end (as
computed with the cac duration and cac start) and the actual cac end as
reported by the driver. During that window, the value of remaining time
outputed by the status command on the socket control interface will
display an overflowed, invalid value.
To mitigate this lets compute the remaining time as signed and display
it only when positive, otherwise defaulting it to 0.
Status command shows something like that when polling every seconds:
state=DFS
cac_time_seconds=60
cac_time_left_seconds=1
...
state=DFS
cac_time_seconds=60
cac_time_left_seconds=0
...
state=DFS

cac_time_left_seconds=4294967292
