When processing 20/40 BSS Coexistence Management frames that do not
explicitly require 40 MHz to be disabled, check whether the reported
channels in 20/40 BSS Intolerant Channel Report element match the
current primary channel. If so, allow 40 MHz operation to continue. This
makes the during-operation updates for 20/40 Operation Permitted more
consistent with the scans during initial BSS startup.
The received 20/40 BSS Intolerant Channel Report channels are to be used
in the OT set in the during-operation determination and the P == OT_i
exception was ignored in the previous implementation which could result
in the AP first starting with 40 MHz and then dropping to 20 MHz on
first received 20/40 BSS Coexistence Management frame even though there
was no change in the neighboring BSSs.

Without this ignoring of the LOW_ACK event, the steering in-progress

hitting an infinite loop in hostapd if a station derived a different PMK

This allows external programs to get the average channel utilization.
The average channel utilization is calculated and reported through
STATUS command. Users need to configure chan_util_avg_period and
bss_load_update_period in hostapd config to get the average channel
utilization.

Recalculate the timeout value for each event instead of calculating this
once and then not allowing the timeout configuration to be changed
without fully stopping and restarting the interface.
This allows the bss_load_update_period configuration parameter to be
modified while a BSS continues operating.

owe_auth_req_process() can return NULL in error cases, but the caller
was not prepared for this. The p pointer cannot be overridden in such
cases since that would result in buffer length (p - buf) overflows. Fix
this by using a temporary variable to check the return value before
overriding p so that the hostapd_sta_assoc() ends up using correct
length for the IE buffer.

This allows wpa_supplicant configuration with phase1="tls_suiteb=1" to
use openssl_ciphers="ECDHE-RSA-AES256-GCM-SHA384" to further limit the
possible TLS cipher suites when using Suite B with RSA >3K keys. This
combination disables use of DHE and as such, mandates ECDHE to be used.

These functions are a bit awkward to use for one-off file loads, as
suggested by the tls_clear_default_passwd_cb() logic. There was also
some historical mess with OpenSSL versions and either not having per-SSL
settings, having per-SSL settings but ignoring them, and requiring the
per-SSL settings.
Instead, loading the key with the lower-level functions seems a bit
tidier and also allows abstracting away trying both formats, one after
another.
