Commands like BSS and GET_NETWORK are used in some cases very frequently
and those can increase the amount of debug information from
wpa_supplicant without significant benefit. These were logged at the
DEBUG level (-d). Move logging of such read-only commands (i.e., no new
wpa_supplicant operation is started based on it) to EXCESSIVE level
(-ddd) which was already used for the PING command.

Previously, the BSS command returned an error if the WSC IE(s) in scan
results could not be parsed. This may be not ideal for all cases, to
instead of rejecting the command completely, return all other
information apart from the WPS information in such a case.

The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.
Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

When P2PS PD with default P2PS method is done, the peer that becomes GO
should authorize the client. However, P2PS specification doesn't require
the client to include its intended interface address in PD
Request/Response. As a result, the P2P Client's interface address may not
be known and any address may need to be authorized.
Previously, client's P2P Device Address was used for authorization,
which is not correct when a dedicated interface is used for P2P Client.
This is not resulting in a connection failure, however it causes a
significant delay (until WPS_PIN_TIME_IGNORE_SEL_REG elapses). Fix this
by authorizing the intended interface address, if known; or any address,
if not known.

Change P2PS P2P-PROV-SHOW-PIN/P2P-PROV-ENTER-PIN event notifications
on PD Request/Response handling to meet required P2PS behavior.
The new implemented scheme:
1. For a legacy P2P provision discovery the event behavior remains
without changes
2. P2PS PD, advertiser method: DISPLAY, autoaccept: TRUE:
Advertiser: SHOW-PIN on PD request replied with a status SUCCESS
Seeker: ENTER-PIN on PD response received with a status SUCCESS
3. P2PS PD, advertiser method: DISPLAY, autoaccept: FALSE:
Advertiser: SHOW-PIN on PD request replied with a status
INFO_CURRENTLY_UNAVAILABLE
Seeker: ENTER-PIN on Follow-on PD request with a status
SUCCESS_DEFERRED
4. P2PS PD, advertiser method: KEYPAD, autoaccept: TRUE/FALSE:
Advertiser: ENTER-PIN on PD request replied with a status
INFO_CURRENTLY_UNAVAILABLE
Seeker: SHOW-PIN on PD response received with a status
INFO_CURRENTLY_UNAVAILABLE
This change in behavior breaks the existing test cases
p2ps_connect_keypad_method_nonautoaccept and
p2ps_connect_display_method_nonautoaccept. Those will be fixed in a
followup commit.

A P2P GO channel switch should not be triggered in all cases that
require channel list update. Specifically, a P2P GO CS should not
be triggered in case that the P2P GO state changed or in case that
that the P2P GO has just completed a CS.

This fixes some issues where a disconnection event may get ignored if an
earlier operation to remove or disable a network resulted in an attempt
to disconnect event though no connection was in place.
wpa_s->current_ssid != NULL alone is not sufficient to determine that
there will be a driver event notifying completion of such disconnection
request. Set own_disconnect_req to 1 only if wpa_s->wpa_state is also
indicating that there is a connection or an attempt to complete one.
This showed up in a failure, e.g., when running the hwsim test case
scan_int followed by ap_vlan_wpa2_psk_radius_required where the latter
ended up not processing a connection failure event and getting stuck not
trying to run a new scan and connection attempt.

This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.
INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).
