Perform NTP lookup at Mobile data connections

If NITZ isn't supported by the current carrier the Android framework
relies instead on a remote NTP server to set the system clock. The
NetworkTimeUpdateService class polls for NTP time during the first 4
minutes after boot, failing to get NTP time within these minutes will
increase the polling interval to 24 hours. Hence, if a data connection
isn't activated directly after boot it can take a long time for the
system clock to be updated. To prevent this situation, NTP lookup is
scheduled as soon as a Mobile data connection has been established.

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.

Bringup NSRM(network socket request manager).

NSRM is a feature to synchronize app socket requests
to reduce network signalling and there by save some power.

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
