8dd5c1b4e9 HS 2.0: Add a command to retrieve icon with in-memory storage
This adds a new command based Hotspot 2.0 icon retrieval option.

In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
   (if needed, repeat with larger offset values until full icon is
   fetched)
5. DEL_HS20_ICON <bssid> <file-name>

REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.

If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.

Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

96e8d831a5 wpa_supplicant: Add SIGNAL_MONITOR command
SIGNAL_MONITOR THRESHOLD=DD HYSTERESIS=DD command will request signal
strength monitoring events based on there having been requested amount
of drop in the signal strength. The threshold value is the RSSI
threshold in dBm for the event to be sent. 0 threshold can be used to
disable monitoring. The hysteresis value is RSSI hysteresis in dB to
specify the minimum amount of change before a consecutive event is
reported.

With nl80211 driver interface, these values map to the
NL80211_CMD_SET_CQM command with NL80211_ATTR_CQM_RSSI_THOLD and
NL80211_ATTR_CQM_RSSI_HYST attributes to the driver.

This command cannot be used when bgscan module is in use since that
depends on being able to control the connection monitoring parameters.

0f039e3432 Add an option to create interface of a certain type with INTERFACE_ADD
Some drivers do not support having two station interfaces, so the fact
that wpa_supplicant always creates a new interface in station mode, even
if it will be used as another type of interface, may prevent
wpa_supplicant from creating new interfaces. Allow setting the interface
type when a new interface is created so that interfaces of supported
types can be created.

Currently supported types are station ("sta") and AP ("ap"). If the
interface type is not specified, a station interface will be created.

dfaf11d648 P2P: Require fresh scan results for persistent group re-invocation
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.

b9da88d6c1 P2PS: Authorize any peer for P2PS method if interface address not known
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.

93f22b4583 P2PS: Fix PD PIN event notifications
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.

e66bcedd3e Do not set own_disconnect_req flag if not connected
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.
