Update CMAS duplicate message detection for carrier requirement.
There is a carrier requirement for CMAS to use only an in-memory
table for duplicate message ID detection. When the max number of
65535 messages is received, the oldest message ID is removed from
the list. After a reboot, a previously received message ID will be
considered a new message. This is required for CMAS lab testing.
The app does not care if there are multiple rows in the SQLite DB
with the same message ID, because the primary key is a unique ID.
Remove the duplicate message detection from the CBContentProvider
and use only the in-memory duplicate detection in CBAlertService.
This is safe for other types of alerts such as ETWS, and has the
benefit that a new alert will not be suppressed due to a very old
alert with the same message ID that was never deleted from the DB.
Message IDs are now stored in an ArrayList as well as a HashSet
in CellBroadcastAlertService. When the 65535 message limit is
reached, an index is used into the ArrayList to remove the oldest
message ID from the HashSet. The new message ID replaces the old
one in the ArrayList, so the size stays fixed at 65535 entries and
no array copies are needed to replace the oldest message ID.

Multiple fixes to CMAS app.
* Allow screen to turn off after 30 seconds for emergency alerts.
* When multiple alerts are received, show them in reverse order.
* After showing the first CMAS alert received on device (other than
Presidential Alert), show opt-out dialog to allow user to
opt-in or out of the various levels of CMAS alert.
* Start/stop animating warning icon in activity pause/resume.
* When multiple non-emergency alerts are received, show them all
(most recent displayed first) when user selects the notification.
* For emergency alerts, start the dialog activity directly instead
of creating a PendingIntent and full screen notification.
* Correctly save/restore the list of alerts in the alert dialog
in onSaveInstanceState() when recreated after screen rotation.
* Fix test app to increment the message ID and to send the correct
alerts when multiple alerts are selected with 5 second delay.

Fix CellBroadcastReceiver to ignore duplicate broadcasts.
Before showing an alert dialog or notification, check to
see if the broadcast message is already in the database.

Add ContentProvider for received cell broadcasts.
Enable apps with android.permission.READ_CELL_BROADCASTS to access the
database of received cell broadcasts via a ContentProvider at URI
"content://cellbroadcasts/". The ContentProvider is read-only, but
provides internal methods for the app to insert and delete broadcasts,
and to mark broadcasts as read. These methods are not exposed to other
applications.
Other changes:
* Added static log() methods for simpler debug logging.
* Moved CellBroadcastDatabase.DatabaseHelper to new top-level
CellBroadcastDatabaseHelper class after refactoring the original
CellBroadcastDatabase class out of existence.
* Removed the "Delete" dialog title per Android UI guidelines,
and changed from a custom view to a built-in dialog type.
