Bluetooth: Set isPreferred to true for PanProfile Connections.

isPreferred is always true for PAN profile so that DUT can
initiate connection with remote device. Curretnly we are
returning true only when pan profile is in connected, so
it will return false when pan profile is not connected and
will never initiate connection on click.

p2p: Fix for GC unable to scan GO after tear down.

A start of the search is not done on a group removed
broadcast event for mLastGroupFormed being set, which
would result in the Group Client not able to find the
GO , though a p2p_find is issued before a disconnect.
This is due to the fact that supplicant shall notify
the p2p device info only once per p2p_find.

To avoid this remove the conditions that is blocking
the search to happen and issue another p2p_find.

P2P: Updates the P2P peer list when there is P2P State Change Action

In the current implementation the P2P window gets updated with the
Peers list only when there is WIFI_P2P_PEERS_CHANGED_ACTION Intent.
Thus the P2P status remains unchanged when there is
WIFI_P2P_STATE_CHANGED_ACTION intent. When there is back and forth
navigation to P2P window, WIFI_P2P_STATE_CHANGED_ACTION intent invokes
the onPeersAvaliable function asynchronously and updates the P2P status
and peers list.

Packages: Fix for SAP turn ON/OFF fails issue.

Turnig ON/OFF SAP repeatedly when WIFI is ON results
in command CMD_SET_AP being received in WifiStaEnabledState
of the state machine, which will not be handled and because
of this SoftAP is not turned ON and we receive no events
thus the check box remains greyed out/disabled.

To resolve this wait for WIFI_STATE_CHANGED intent before
re-enabling the SAP.
