This introduces new AKM for SAE and FT-SAE and adds the initial parts
for going through the SAE Authentication frame exchange. The actual SAE
algorithm and new fields in Authentication frames are not yet included
in this commit and will be added separately. This version is able to
complete a dummy authentication with the correct authentication
algorithm and transaction values to allow cfg80211/mac80211 drivers to
be tested (all the missing parts can be handled with
hostapd/wpa_supplicant changes).

Otherwise it's difficult to determine if the supplicant was built with
CONFIG_AP, CONFIG_IBSS_RSN, CONFIG_P2P, etc. CONFIG_AP and CONFIG_P2P
can be inferred from the introspection data of the Interface object,
but CONFIG_IBSS_RSN does not change the introspection data at all and
thus it's impossible to determine whether the supplicant supports it
without knowing its compile-time options.

The wpa_s->p2p_in_provisioning flag did not get cleared in some cases
where p2p_cancel command is used to stop group formation. This can result
in some operations (like p2p_find) failing afterwards. Fix this by using
wpas_group_formation_completed() when processing p2p_cancel for a group
that has not yet completed group formation.

External programs can use this new parameter to prevent wpa_supplicant
from connecting to a list of BSSIDs and/or SSIDs. The disallowed BSSes
will still be visible in scan results and it is possible to run ANQP
operations with them, but BSS selection for connection will skip any
BSS that matches an entry in the disallowed list.
The new parameter can be set with the control interface SET command
using following syntax:
SET disallow_aps <disallow_list>
disallow_list ::= <ssid_spec> | <bssid_spec> | <disallow_list> | “”
SSID_SPEC ::= ssid <SSID_HEX>
BSSID_SPEC ::= bssid <BSSID_HEX>
For example:
wpa_cli set disallow_list "ssid 74657374 bssid 001122334455 ssid 68656c6c6f"
wpa_cli set disallow_list
(the empty value removes all entries)

Commit 6b56cc2d97 added clearing of the
p2p->pending_action_state too early in this function. This should not
be done if we are going to silently ignore the frame due to dialog
token mismatch. Fix this by moving the code around to check the dialog
token first.
This issue resulted in PD Request retries getting stopped too early if
the peer is sending out an unexpected PD Response (e.g., because of it
being excessively slow with the response so that the response is
received only after the next TX attempt with a new dialog token).

It is possible for the P2P client group to be removed while waiting for
a pending scan operation (e.g., when p2p_group_idle timeout hits after
getting disconnected from the GO with something else than
Deauthentication with reason code 3). If this happens with a P2P
interface that is used both for P2P Device and group roles, scan state
could get stuck while waiting for the next scan to complete since no
more station (P2P client) mode scans are scheduled. Fix this by clearing
sta_scan_pending when removing the temporary group network block.

Make Invitation process for re-invoking a persistent group behave
similarly to GO Negotiation as far as channel negotiation is concerned.
The Operating Channel value (if present) is used as a starting point if
the local device does not have a forced operating channel (e.g., due to
concurrent use). Channel lists from devices are then compared to check
that the selected channel is in the intersection. If not, channel is
selected based on GO Negotiation channel rules (best channel preferences
etc.). Invitation Request is rejected if no common channel can be
selected.

If two P2P_FIND commands and a station mode SCAN command are issued in a
sequence with the second P2P_FIND and SCAN commands started before the
initial scan from the first P2P_FIND command has completed,
sta_scan_pending may be left set without an automatic way of getting it
cleared. This can get P2P search stuck if no further station mode scan
operations are run.
Fix this by clearing the sta_scan_pending flag whenever station mode scans
are stopped due to no enabled networks resulting in INACTIVE mode getting
entered. In addition, avoid setting sta_scan_pending flag when a special
scan_res_handler is set so that this does not get enabled on the P2P
Device interface during a P2P search operation.

If there are any disabled networks, show a debug print with the count

The ASCII hexdump is somewhat difficult to search for (especially on
Android builds), so make the debug log easier to parse by printing the
full control interface command as a text string. In addition, use
wpa_dbg() to get the interface name printed so that multi-interface
cases can be debugged.

Setting just ssid->passphrase is not enough to complete the network
block for the GO entry. Also the PSK needs to be derived so that the
network is considered enabled by wpas_network_disabled(). The previous
version worked as long as something else allowed the scan request to be
performed (this is needed even though the actual scan is skipped when
starting GO).
The first GO start was allowed because wpa_s->scan_req is initialized to
1 in wpa_supplicant_alloc(). However, other attempts may fail if
wpa_s->scan_req is cleared. This failure shows up as "No enabled
networkas - do not scan" in debug log followed by state change to
INACTIVE when trying to start GO.
Fix this by deriving PSK from the passphrase for GO mode.

Commit 30ee769235 started skipping P2P
group removal if wpa_s->current_ssid is not set and commit
0d30cc240f started clearing
wpa_s->current_ssid on disconnection. This combination broke
p2p_group_idle timeout on P2P client interface in a case where no
separate P2P group interface is used and when the disconnection is
triggered by something else than an explicit indication of GO
terminating the group.
Fix this by relaxing network block matching rules when figuring out
whether any of the configured network blocks could be in P2P use. The
p2p_group flag alone should be enough for this since temporary P2P group
network blocks are removed once the P2P group is terminated.

If the AP creation failed (missing freq= or driver error) the supplicant
would previously stay in SCANNING state forever. Instead, it should

If a connection operation is started on an interface based on scan
results, other virtual interfaces should not be information about the
results to avoid potential concurrent operations during the association
steps. Since the sibling notification of scan results received was added
as an optimization, skipping it for this type of cases is the simplest
way of avoiding unnecessary concurrent operations.

Since we have a global P2P module, the flag to trigger scan completion
events to it needs to be in similar context. The previous design
maintained this separately for each virtual interface and if P2P module
did not run its scan operation on the virtual interface that completed
the scan, P2P module would not be allowed to restart operations
properly.
