Convert FT RRB into a new TLV based format. Use AES-SIV as AEAD cipher
to protect the messages.
This needs at least 32 byte long keys. These can be provided either
by a config file change or letting a KDF derive the 32 byte key used
from the 16 byte key given.
This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

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.

If the driver provides input on MBO transition candidate handling, the
target value in get_mbo_transition_candidate() can be NULL if the driver
provided BSSID is not found in the wpa_supplicant BSS table. And later
it would be dereferenced. Fix this by adding an explicit check before
dereferencing the pointer.

The check for erp->keyname_nai within eap_erp_get_key() is apparently

Commit 941caed980 ('MBO: Add MBO
ANQP-element processing on AP') changed the design by using the
rx_anqp_vendor_specific() function to process all ANQP vendor specific
elements. However, the caller for this was within ifdef CONFIG_HS20
block. Fix this by calling the function even in CONFIG_HS20=y is not
included in the build. This fixes CONFIG_MBO=y builds without
CONFIG_HS20=y.

Disconnection due to DISABLE_NETWORK while being connected was resulting
in the AP getting blacklisted. Avoid this by setting own_disconnect_req

ieee802_1x_kay_move_live_peer() did not check
ieee802_1x_kay_get_potential_peer() result explicitly and a static
analyzer reported a warning about the possible NULL result. This cannot
really happen in practice since the only caller of
ieee802_1x_kay_move_live_peer() verifies that the specific peer entry is
available. Anyway, it is easy to silence the false warning by adding an
explicit check here and cover any other potential case if another caller
is added.

If the uuid configuration parameter is not set, wpa_supplicant generates
an UUID automatically to allow WPS operations to proceed. This was
previously always using an UUID generated from the MAC address. This
commit adds an option to use a random UUID instead. The type of the
automatically generated UUID is set with the auto_uuid parameter: 0 =
based on MAC address (default; old behavior), 1 = random UUID.
