Fix possible NPE in SyncHandler.onBootCompleted()

If onBootCompleted() was called a second time, it would have throw a
NullPointerException since the queue object would have already been
set to null by the previous call. This commit just makes such an
object behave as an empty queue instead of throwing the exception.

frameworks/base: Fix binder parcel leak with getMetadata() API

When VideoView calls getMetadata API of MediaPlayer, parcel object
is getting allocated by MediaPlayer and metadata is created over
parcel object. This metadata object is returned to the VideoView
which is being GC without calling recycle on parcel which was
creating leak in binder virtual memory.

server: clear forwarding rules when tethering is disabled

Since disabling NAT needs tethered iface's address info,
but sometimes the iface goes down before disabling NAT, this fix
just caches the iface's address.

Use a content observer for getting the default APN

Instead of executing a query of the database for the
default APN on every network state change, an observer
is used on the database to be notifited when the apn
has changed. This prevents unneccesary queries on the
the database.

Revert " Audio: SetForceUse config check in AudioService"

This reverts commit 0af88afe6dc16760b57afa74ca42e40fbe6ff9cf.

- During playback over BT using the Google Play Music app,
  if BT is disconnected through the app and playback is resumed,
  it continues over BT and not the speaker.
- The original commit forces playback to continue over BT
  although it is disconnected.
- Reverting the commit fixes this issue and the issue
  addressed by the commit is also not observed after reversion.
