While creating a cloned PMKSA entry for OKC both expiration and
reauth_time values are set to maximum values, but later only the
expiration time is copied from the old PMKSA entry to the new PMKSA
entry. Due to this there is a possibility of reauth_time becoming
greater than expiration time in some cloned entries. To avoid this copy
reauth_time also to the cloned entry.
Also, add check to reject control interface commands with reauth time
greater than expiration time.

Support adding/deleting vendor elements dynamically for AP mode while it
is started by wpa_supplicant instead of hostapd which already supported
this. This adds ap_assocresp_elements global parameter and UPDATE_BEACON
control interface command to take the changed values into effect.
Usage in wpa_cli:
Add vendor IE for (Re)Association Response frames
> set ap_assocresp_elements=xxxx
Add vendor IE for Beacon/Probe Response frames
> set ap_vendor_elements=xxxx
Delete vendor IE from (Re)Association Response frames
> set ap_assocresp_elements
Delete vendor IE from Beacon/Probe Response frames
> set ap_vendor_elements
To make vendor IE changes take effect
> update_beacon

Enhance the P2P_GROUP_ADD command to support DFS channel with 80 and 160
MHz bandwidth to be used for autonomous GO when using offloaded DFS.
For example, 'P2P_GROUP_ADD freq=5500 max_oper_chwidth=80 ht40 vht'
- Previous behavior: AP fallback to channel 100 using 20 MHz with
"No VHT higher bandwidth support for the selected channel 100"
- Enhanced behavior: AP starts on channel 100 using 80 MHz with
"VHT center channel 106 for 80 or 80+80 MHz bandwidth"
This functionality is on top of the driver's capability to offload DFS,
which is advertized through WPA_DRIVER_FLAGS_DFS_OFFLOAD.

External applications can store PMKSA entries persistently and
reconfigure them to wpa_supplicant after restart. This can result in
wpa_supplicant having a PMKSA for FILS authentication without having
matching ERP keys for it which would prevent the previously added
mechanism for dropping FILS PMKSA entries to recover from rejected
association attempts.
Fix this by clearing PMKSA entries configured by external applications
upon FILS connection failure even when ERP keys are not available.

The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes scan results to
be reported. Since the reassociate bit is set, this will trigger a
connection attempt based on the aborted scan's scan results and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.
Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.

The newer kernel versions enforce strict netlink attribute policy
validation and will cause cfg80211 to reject vendor commands with
NL80211_ATTR_VENDOR_DATA if NLA_F_NESTED attribute is not set but
if the vendor command is expecting nested data within
NL80211_ATTR_VENDOR_DATA attribute.
Most of the earlier instances were addressed by adding NLA_F_NESTED
flag in nla_nest_start(). This commit addresses the remaining
instance in which NL80211_ATTR_VENDOR_DATA is populated using data
set by user through the control interface.
Enhance the control interface VENDOR command to indicate whether the
vendor subcommand uses nested attributes within NL80211_ATTR_VENDOR_DATA
attribute or not.

Within wpas_connection_failed(), the 'count' value of wpa_blacklist is
erroneously used as a tally of the number times the device has failed
to associate to a given BSSID without making a successful connection.
This is not accurate because there are a variety of ways a BSS can be
added to the blacklist beyond failed association such as interference
or deauthentication. This 'count' is lost whenever the blacklist is
cleared, so the wpa_supplicant stores an additional value
'extra_blacklist_count' which helps persist the 'count' through clears.
These count values are used to determine how long to wait to rescan
after a failed connection attempt.
While this logic was already slightly wrong, it would have been
completely broken by the upcoming change which adds time-based
blacklisting functionality. With the upcoming change, 'count' values
are not cleared on association, and thus do not necessarily even
approximate the "consecutive connection failures" which they were being
used for.
This change seeks to remove this unnecessary overloading of the
blacklist 'count' by directly tracking consecutive connection failures
within the wpa_supplicant struct, independent of the blacklist. This new
'consecutive_conn_failures' is iterated with every connection failure
and cleared when any successful connection is made. This change also
removes the now unused 'extra_blacklist_count' value.
