While the listed unknown operating class/channel number pairs need to be
ignored, that should be done in a manner than prevents the parsed
bootstrapping info from being used as if it had no channel list (i.e.,
allowing any channel) if there are no known operating class/channel
number pairs.

This simplifies dpp_build_conf_obj_dpp() and makes it easier to share

"SET dpp_version_override <ver>" can now be used to request

If the Enrollee indicates support for DPP R2 or newer, add Connector and
C-sign-key in psk/sae credentials (i.e., cases where DPP AKM is not
enabled) for reconfiguration. Extend processing of such credentials in
wpa_supplicant network profile addition to handle this new case
correctly by not setting key_mgmt=DPP based on Connector being present,
but by looking at the actual akm value in the config object.

This avoids unexpected behavior if GAS query fails and the Config
Response does not get processed at all. Previously, this could result in
configuration being assumed to be successful instead of failure when
Config Response object was not received at all. That could result in
undesired Config Result frame transmission with DPP Rel 2 and not
clearing the ongoing DPP session.

Previously, unexpected Authentication Confirm messages were ignored in
cases where no Authentication Confirm message was expected at all, but
if this message was received twice in a state where it was expected, the
duplicated version was also processed. This resulted in unexpected
behavior when authentication result was processed multiple times (e.g.,
two instances of GAS client could have been started).
Fix this by checking auth->waiting_auth_conf before processing
Authetication Confirm. That boolean was already tracked, but it was used
only for other purposes.
