Alarm: ignore less than 2 mins upcomming power off alarm

2 minutes is our define for enough boot up time for a power off alarm.
For current design, it can only afford upcoming power off alarm which
is later than 2 minutes. Kernel alarm driver only take care the power
off alarm which is 2 minutes later. And the framework only pass the
first power off alarm to kernel. So we need to find the first 2
minutes later upcomming power off alarm to kernel, otherwise it will
be no power off alarm from kernel's perspective. Fix the bug by
ignoring less than 2 mins upcomming alarm as power off alarm, and
only treat it as a normal alarm.

ExtMediaPlayer: Increase parcel pool size to 30

Increase MAX_NUM_PARCELS to 30. This is to handle
parcel override issue when textsamples are sent at
a fast pace from mediaplayer.
Usecase: With CEA CC streams, dashplayer sendTextPacket
embedded in each video sample as soon as decoded.
No realtime offset delay sync logic for text samples
as with A/V samples. When samples drained in batch,
can have more than 5 textsamples sent in flurry

AlarmMangerService: Fix the delay of ACTION_TIME_CHANGED for time-services

After boot completed, if low memory condition happens or some ordered
broadcasts have time out, it will cause delay for some receivers to
receive ordered broadcasts. Adding FLAG_RECEIVER_FOREGROUND into
time changed action will make TimeServiceBroadcastReceiver receive
ACTION_TIME_CHANGED in time.
