SystemUI: don't crash when user disable default apps

If the user has disabled the default clock or calendar application,
System UI will crash when the user clicks the Clock or Calendar
from the notification bar. This patch fixes the issue.

Clear the scan list when an empty list is received

When the framework receives an empty scan list from supplicant, it does
not clear the local list. So the UI will continue to show the previous
scan list even when there are no APs around. So clear the local list,
when an empty list is received.

wlan: Error handling on PNO failure due to active P2P session.

If set PNO fails due to concurrent active p2p sessions,
handle the error condition in framework and issue a
regular scan for every framework background scan interval
until set PNO is either success or disabled.

Close sockets on wpa_supplicant termination.

Framework does not close the sockets on supplicant
termination, leading to leakage of file descriptors.

Thus close the socket on supplicant termination.

frameworks/base: add app launch timeline instrumentation

Displayed Activity is often being used to measure application
launch times. However Displayed Activity only accounts for a
subset of the app launch. This additional instrumentation will
allow for more accurate measurements of applications launch
times.

wlan: Fix for delay in PNO scan trigger after p2p disconnect.

If PNO is disabled due to concurrent active p2p session,
on P2P disconnect PNO scan is not triggered until the next
framework scan is scheduled.
To mitigate this issue trigger the PNO scan on receiving
P2P_CONNECTION_CHANGED intent in disconnect state of the
wifi state machine.
