This adds core SAE functionality for a new mode of using SAE with a
specially constructed password that contains a fingerprint for an AP
public key and that public key being used to validate an additional
signature in SAE confirm from the AP.

Convert the previously used text log entries to use the more formal
OCV-FAILURE prefix and always send these as control interface events to
allow upper layers to get information about unexpected operating channel
mismatches.

Make reporting of OCV validation failure reasons more flexible by
removing the fixed prefix from ocv_verify_tx_params() output in
ocv_errorstr so that the caller can use whatever prefix or encapsulation
that is most appropriate for each case.

To support the STA testbed role, the STA has to use specified channel
information in OCI element sent to the AP in EAPOL-Key msg 2/4, SA Query
Request, and SA Query Response frames. Add override parameters to use
the specified channel while populating OCI element in all these frames.

It was possible for the RSN state machine to maintain old PMKSA cache
selection (sm->cur_pmksa) when roaming to another BSS based on
driver-based roaming indication. This could result in mismatching state
and unexpected behavior, e.g., with not generating a Suite B PMKSA cache
entry.

Address possible handover request collisions for cases where both
devices try to initiate handover simultaneously.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
The previous version was trying to force the handover roles based on the
--init-on-touch parameter on both sides. That is fine for some test
scenarios, but not appropriate for more normal use cases. Change this
design to enable handover server in all cases and only control starting
of the handover client based on --init-on-touch.
