Replace the previously used extension of IEEE 802.11 managed Ethertype
89-0d (originally added for Remote Request/Response in IEEE 802.11r)
with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP
communication. The new design uses a more properly assigned identifier
for the messages.
This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new
hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP),
and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH
protocol.
This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

This adds an option to configure hostapd to enable use of perfect
forward secrecy option in FILS shared key authentication. A new build
option CONFIG_FILS_SK_PFS=y can be used to include this functionality. A
new runtime configuration parameter fils_dh_group is used to enable this
by specifying which DH group to use. For example, fils_dh_group=19 would
allow FILS SK PFS to be used with a 256-bit random ECP group.

Previously, CONFIG_IEEE80211R enabled build that supports FT for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode FT is required and there is no need for AP mode FT.
Add support to differentiate between station mode FT and AP mode FT in
wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used
when AP mode FT support is required in addition to station mode FT. This
allows binary size to be reduced for builds that require only the
station side FT functionality.

This changes 4-way handshake authenticator processing to decrypt the
EAPOL-Key frames using an AEAD cipher (AES-SIV with FILS AKMs) before
processing the Key Data field. This replaces Key MIC validation for the
cases where AEAD cipher is used. This needs to move the EAPOL-Key msg
2/4 RSN element processing to happen only after the PTK has been derived
and validated. That is done for all AKMs to avoid extra complexity with
having to maintain two code paths for this.

Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.
The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.
New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.
When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.
To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.
Though not depended on by the code, vlan_id assignment ensures:
* vlan_id = 0 will continue to mean no AP_VLAN interface
* vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
with no per_sta_vif and no extra tagged vlan.
* vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.
This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.
DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.
MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.
Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).
Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

prints allowed (-K on the command line), it is possible for passwords
and keying material to show up in debug prints. Since some of the debug

purposes, a copy of such password may remain in heap. Clear these
