WifiController: fix high perf lock sometimes not respected

When the device screen is turned off, the state is DeviceActive for
15 minutes. In this time, high perf lock is not respected and
Wi-Fi power-saving mode will be turned on because screen is off.

Fix by adding a new DeviceActiveHighPerfState.

P2P: reset mIsInvite flag when p2p transitions to inactive state

Commit Ifaeb6a8c5f9cddd7df96622056541e22aad74314 has set mIsInvite
to true when the invitation request is obtained from the peer to
ensure that the DUT does issue p2p connect with the intention to
join when the user accepts the invitation. However, this did  not
consider the case where the user has rejected the invitation request
which shall still set mIsInvite to true. This shall result in an issue
when the DUT shall initiate a GO Negotiation with a peer for the next
time. The DUT shall end up joining with the peer (because of the value
of mIsInvite being true) rather than doing a GO Negotiation. Thus reset
the value of mIsnivite whenever the transition happens to the InactiveState.

WiFi : Fix for  DHCP to Static IP configuration problem

WifiStateMachine shall update the IP address configuration to
the kernel through NetworkManagementService.This notification
from the kernel is again sent to the connectivity service
through the NetLinkStateTracker and WiFiStateMachine.
Thus ,if the interface is down during this IP address
reconfiguration (for the case of DHCP to Static IP configuration),
Connectivity service shall be notified with old IP address ,NULL(0)
IP address(signifying interface down) and the latest IP address.
This notification was done by updating the IP address using a local
variable , and hence the second notification on the interface down
is overridden by the last notification , resulting in missed
interface down notification to the connectivity service.This
resulted in failed data connection when IP address is changed from
DHCP to IP on the fly.
Hence ,this gerrit enhances the design and also pass the updated
IP address to the connectivity service.

wifi: Provide fix for no connect status for a network with WPA-PSK followed by WPS

WifiConfigStore maintains the state of each configured Wifi profile.
These profiles are maintained to create a one-to-one mapping between
the profile and the IP configuration. The same list is also used
to display the connected profiles.

While creating list of valid network configurations, the profiles
with same SSID but different security and authentication credentials
are considered duplicate. Thus the profile created due to WPS
connection attempt is not added to the list maintained by WifiConfigStore.
This results in the framework not displaying the new network as connected,
as the supplicant shall give the connect indication on the new network id
which shall not get added. Thus, overwrite the previous duplicate-disabled
configuration to fix this issue.

wifi: Reduce the frequency of scans when in disconnected state and display ON

When STA is not connected, display is ON and there are no saved profiles then
reduce frequent scans due to scan alarm source by increasing scan alarm time
mCurrentScanAlarmMs to 5 minutes since there is already a periodic scan every
mSupplicantScanIntervalMs (15 seconds). If there are saved profiles then keep
mCurrentScanAlarmMs to 10 seconds.

THRESHOLD_UNBLACKLIST_SOFT_5G
THRESHOLD_UNBLACKLIST_HARD_24G
THRESHOLD_UNBLACKLIST_SOFT_24G
THRESHOLD_INITIAL_AUTO_JOIN_ATTEMPT_RSSI_MIN_5G
THRESHOLD_INITIAL_AUTO_JOIN_ATTEMPT_RSSI_MIN_24G
Hence reverting the gerrit
