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.

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.
