Enable both the hunting-and-pecking loop and hash-to-element mechanisms
by default in OpenWRT with SAE.
Commercial Wi-Fi solutions increasingly frequently now ship with both
hunting-and-pecking and hash-to-element (H2E) enabled by default as this
is more secure and more performant than offering hunting-and-pecking
alone for H2E capable clients.
The hunting and pecking loop mechanism is inherently fragile and prone to
timing-based side channels in its design and is more computationally
intensive to perform. Hash-to-element (H2E) is its long-term
replacement to address these concerns.
For clients that only support the hunting-and-pecking loop mechanism,
this is still available to use by default.
For clients that in addition support, or were to require, the
hash-to-element (H2E) mechanism, this is then available for use.

The 80211r r0kh and r1kh defaults are generated from the md5sum of
"$mobility_domain/$auth_secret". auth_secret is only set when using EAP
authentication, but the default key is used for SAE/PSK as well. In
this case, auth_secret is empty, and the default value of the key can
be computed from the SSID alone.
Fallback to using $key when auth_secret is empty. While at it, rename
the variable holding the generated key from 'key' to 'ft_key', to avoid
clobbering the PSK.

Up to now the WPS script triggered WPS on the stations only if it
could not trigger it successfully on any hostapd instance.
In a Multi-AP context, there can be a need (to establish a new
wireless backhaul link) to trigger WPS on the stations, regardless of
whether there is already a hostapd instance configured or not. The
current script makes it impossible, as if hostapd is running and
configured, WPS would always be triggered on hostapd only.
To allow both possibilities, the following changes are made:
- Change the "pressed" action to "release", so that we can make use of
the "$SEEN" variables (to know for how long the button was pressed).
- If the button is pressed for less than 3 seconds, keep the original
behavior.
- If the button is pressed for 3 seconds or more, trigger WPS on the
stations, regardless of the status of any running hostapd instance.
- Add comments explaining both behaviors.
- While at it, replace the usage of '-a' with a '[] && []'
construct (see [1]).
This gives users a "fallback" mechanism to onboard a device to a
Multi-AP network, even if the device already has a configured hostapd
instance running.

Both hostapd and netifd attempt to add a VLAN device to a bridge.
Depending on which one wins the race, bridge vlan settings might be incomplete,
or hostapd might run into an error and refuse to service the client.
Fix this by preventing hostapd from adding interfaces to the bridge and
instead rely entirely on netifd handling this properly

When using htmode 'HE20' with a radio mode that uses wpa-supplicant
(like mesh or sta), it will default to 40 MHz bw if disable_ht40 is not
set. This commit fixes this behaviour.

With the default configuration we generate, the supplicant starts
scanning and tries to connect to any open network when the interface
is enabled.
In some cases it can be desirable to prevent the supplicant from
scanning by itself. For example, if on the same radio an AP is
configured and an unconfigured STA is added (to be configured with
WPS), the AP might not be able to beacon until the STA stops
scanning.
In such a case, the STA configuration can still be required to set
specific settings (e.g. multi_ap_backhaul_sta) so it can't be set to
"disabled" in uci (because that would prevent the supplicant from
being run at all). The alternative is to add the "disabled" parameter
to the default network block in the supplicant configuration.
This patch adds a "default_disabled" setting in UCI which, when set,
adds the "disabled" parameter to the supplicant default network block.

In the aftermath of the KRACK attacks, hostapd gained an AP-side workaround
against WNM-Sleep Mode GTK/IGTK reinstallation attacks. WNM Sleep Mode is not
enabled by default on OpenWrt, but it is configurable through the option
wnm_sleep_mode. Thus, make the AP-side workaround configurable as well by
exposing the option wnm_sleep_mode_no_keys. If you use the option
wpa_disable_eapol_key_retries and have wnm_sleep_mode enabled, you might
consider using this workaround.

Commit 0a7657c ("hostapd: add channel utilization as config option") added the
two new uci options bss_load_update_period and chan_util_avg_period. However,
the corresponding "config_add_int" calls for these options weren't added, so
attempting to actually use these options and change their values is bound to
fail - they always stay at their defaults. Add the missing code to actually
make these options work.

The country3 option in hostapd.conf allows the third octet of the country

Make it possible to specify the SAE mechanism for PWE derivation. The
following values are possible:
0 = hunting-and-pecking loop only
1 = hash-to-element only
2 = both hunting-and-pecking loop and hash-to-element enabled
hostapd currently defaults to hunting-and-pecking loop only.
