Alarm: Add one more RTC alarm type for poweroff alarm.

Now we use type of RTC_WAKEUP for the poweroff alarm.
Actually lots of other applications also use this type.
But these applications never expect the device will
power on after it has been shut down. So we need to
add dedicated alarm type for the Deskclock or similar
applications.

alarm: add JNI interface for clearing alarm

Add the JNI for clearing cancelled alarm, otherwise kernel driver
would know nothing about the alarm status. E.g. power-off alarm
would not be really cleared in alarm driver even it is cancelled
in the apps/framework.

Fix alarm wakelock not being released.

Alarm wakelock was not released when the pending intent was served
by the package with a uid not the same as the one which created the
alarm.
Remove advanced for loop from PowerManagerService since the list is
modified during iteration and thus resulting to
ConcurrentModificationException error

Wifi: wifi not connecting, once the APN gets disabled state

APNs are disabled on select network and they are enabled on
receiving connected event. But forgetting an APN before the
connected event is received,will result all the remaining APN
to be in disabled state and they never connect.
So, Enabling all the disabled APN on forget network will help
to connect automatically to a saved APN.

 Audio: SetForceUse config check in AudioService

 - Audio is routed to headset when BT is turned off while audio is
   played on speaker
 - Mediarouter does not have setForce device information when app forces
   audio to speaker. So while disconnecting BT, MediaRouter is routing
   audio to headset instead of speaker.
 - Added check for setforce config in AudioService.
