FILS: Check for potential NULL return

hostapd_eid_assoc_fils_session() might return NULL if memory allocation
fails. This NULL value then will be used for invalid calculation and
cause unspecified behavior or be dereferenced unexpectedly. Avoid this
with an explicit check of the returned pointer.

RSNO: Protect wpa_ie_buf3 from reuse explicitly

Use else-if check for better clarity regarding usage of wpa_ie_buf3 to
make it explicit that memory is allocated for this pointer only once.

RSNO: Remove override elements from EAPOL-Key msg 3/4

This was not done in case the STA did not use RSN overriding.

wlantest: Remove unused QoS handling from GCMP nonce generation

This was copied from CCMP, but is not needed (and can trigger compiler
warnings) with GCMP.

Testing functionality to allow EAPOL-Key Reserved field to be set

The new hostapd configuration parameter eapol_key_reserved_random=1 can
be used for testing STA/Supplicant functionality to accept a random
value in the Reserved field within EAPOL-Key frames.

Allow RSNE/RSNXE/RSNOE/RSNO2E/RSNXOE to be replace for testing

This is convenient for testing STA behavior with various RSN element
combinations and special cases.

RSNO: Support over two octets of RSNXOE capabilities

The RSNXE generation function was extended to support this earlier, but
that update was missed from the RSNXOE variant.

RSNO: Allow RSNXE to be omitted

Add an explicit rsn_override_omit_rsnxe=1 configuration parameter to
allow the RSNXE to be omitted when using the RSNXOE and wanting to
minimize interoperability issues with STAs that might recognize the
RSNXE, but not handle it correctly, e.g., when multiple octets of
payload is included.

Enhance select_network() to trigger new scans in some cases

wpa_supplicant select_network() relies on fast_associate to reuse old
scan results. However, this approach does not apply in some cases in
Android:

1 - If the selected network is hidden, and the SSID is in Chinese,
Android switches between fallback SSIDs, necessitating a new scan for
switching between different hidden SSIDs.

2 - Similarly, if the selected SSID is OWE (Opportunistic Wireless
Encryption), and the OWE SSID bands have been changed, select_network()
requires a fresh scan to discover hidden OWE SSIDs.

To address these, enhance select_network() to trigger new scans instead
of relying on fast_associate. This improves network selection behavior
in Android.
