Commit faf9a8585d added mechanism for
selecting 2.4 or 5 GHz band for scan operation. However, no mechanism
for setting the setband value was added at that time. This commit adds a
new SET ctrl_iface parameter to allow the setband functionality to be
used. "SET setband <AUTO/5G/2G>" can be used to select all bands, 5 GHz
band only, or 2.4 GHz band only.

Android framework maintains a state to process the scan results after
the scan is issued. If wpa_supplicant issues the scan during the
initialization, the one issued by the framework may fail (with EBUSY) if
the host driver is already processing the scan. Thus, the scan results
returned for the first scan triggered by wpa_supplicant are not
processed for getting displayed resulting in delay for the display of
the first scan results after the Wi-Fi subsystem initialization. Thus,
trigger the scan only based on the framework request on Android.

FAIL-BUSY was already returned for the case where a scan had been
started, but with the radio work design, it would have been possible to
schedule multiple scan requests if a non-scan radio work was in
progress. Multiple back-to-back scans are not usually very helpful, so
reject this type of cases where the SCAN command would be used to build
such a sequence.

The mesh gate is used to bridge (or route) between mesh network and
another network. For example, mesh gate acts as router between mesh
network and IEEE 802.11 BSS network.
This command makes a virtual mesh interface to be used for mesh gate.
This command expects to be used like this.
wpa_cli -i wlan0 MESH_INTERFACE_ADD ifname=mesh0
wpa_cli -i mesh0 add_network
wpa_cli -i mesh0 set_network 0 ssid '"commell_2X_mmm"'

Previously, any P2P capable interface was skipped in cross connection
uplink consideration. However, this ends up skipping more or less all
nl80211-based driver cases now since they mark the main interface P2P
capable. Relax this rule to allow the parent interface to be used as the
non-P2P station interface for cross connection purposes.

This is needed to get into more consistent state after the FLUSH
command. DISCONNECT followed by FLUSH could result in
wpa_s->disconnected being left to 1 and this resulted in a test failure,
e.g., when running wpas_ctrl_dup_network followed by
wpas_ctrl_enable_disable_network where the latter was expecting
ENABLE_NETWORK on a disabled network to connect automatically and that
does not happen if wpa_s->disconnected == 1.

wpa_bss_in_use() used to determine that a BSS with BSSID of
00:00:00:00:00:00 is in use in almost every case since either
wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This
could result in a corner case of a BSS entry remaining in the BSS table
indefinitely if one was added there with a (likely bogus) address of
00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and
wpa_s->pending_bssid if the BSSID in the BSS table entry is
00:00:00:00:00:00.
In theory, that address is a valid BSSID, but it is unlikely to be used
in any production AP, so the potential expiration of a BSS entry with
that address during a connection attempt would not be a concern
(especially when a new scan would be enough to recover from that).
