This is not perfect and only works if the CC is known via
the GSM radio and is only accurate if there is one time zone
per country. This does nothing to resolve time zone problems
for wifi only devices.
So this is a partial fix for bug 2896745

Moved more configuration into config.xml so we can tweak settings
like the default journal mode, WAL auto-checkpoint interval and
so on.
This change itself should not introduce any functional differences.

When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

Combine the code for opening readable and writable databases.
This improves the handling of the case where a database cannot
be opened because it cannot be upgraded. Previously we would
open the database twice: first read-write, then read-only, each
time failing due to the version check. Now only open it once.
Removed the goofy locking logic related to upgrading a read-only
database to read-write. We now do it in place by reopening the
necessary connections in the connection pool.

This is a problem only when using TextView's internal scroll.
Since there was no bug report about this obvious problem, it
looks like most EditText are single ine or located inside of
a ScrollView.

An "UpdateLock" works similarly to a wake lock in API: the caller is
providing a hint to the OS that now is not a good time to interrupt
the user/device in order to do intrusive work like applying OTAs.
This is particularly important for headless or kiosk-like products
where ordinarily the update process will be automatically scheduled
and proceed without user or administrator intervention.
UpdateLocks require that the caller hold the new signatureOrSystem
permission android.permission.UPDATE_LOCK. acquire() and release()
will throw security exceptions if this is not the case.
The "is now convenient?" state is expressed to interested parties
by way of a sticky broadcast sent only to registered listeners. The
broadcast is protected; only the system can send it, so listeners
can trust it to be accurate. The broadcast intent also includes a
timestamp (System.currentTimeMillis()) to help inform listeners that
wish to implement scheduling policies based on when the device became
idle.
The API change here is a tiny one: a dump(PrintWriter) method has been
added to the TokenWatcher class to facilitate getting information out
of it for dumpsys purposes. UpdateLock itself is still @hide.

Refactor SMS Cell Broadcast support to enable receiving CMAS warning
notifications over CDMA. The CellBroadcastReceiver app must also be
updated with the corresponding change. All cell broadcasts are now
delivered as a Parcelable SmsCbMessage object in the "message" extra
of the SMS_CB_RECEIVED_ACTION or SMS_EMERGENCY_CB_RECEIVED_ACTION,
instead of as a GSM/UMTS "pdu" byte array.
Existing functionality for ETWS and CMAS alerts over GSM/UMTS continues
to be supported using the new radio-technology independent SmsCbMessage
and related objects. Test cases are added to verify that valid and
invalid broadcast data is handled appropriately.
Unit testing discovered a bug in the BitwiseOutputStream utility class
used by the added test cases. When the BitwiseOutputStream object must be
expanded (in the private possExpand() method), the mEnd field is not
updated to the new array size. This causes a new array to be allocated
on every new write, and for all data beyond the original array allocation
to be replaced with zeroes. Fixed by adding a line to possExpand() to
update mEnd. Added a test case to BitwiseStreamsTest to verify the fix.
Besides the test cases, BitwiseOutputStream is only used by BearerData in
two places, both of which allocate a sufficient initial buffer. So the
bug in BitwiseOutputStream is not critical to fix for normal operation,
but should be fixed so that the test cases using it function correctly.

Bug 6083776
While WebKit limits the length of a field with maxlength, the
InputConnection can get out of sync with it when it doesn't
recognize that the characters haven't been changed. Adds
maximum field length to WebViewInputConnection to limit the
characters typed.

Allow disk access during application and provider setup. This could
block processing ordered broadcasts, but later processing would
probably end up doing the same disk access.
