Major refactoring of Bluetooth settings classes.
- Moved all functionality from LocalBluetoothManager into new
LocalBluetoothAdapter and LocalBluetoothPreferences, and into
existing classes.
- Refactored functionality from BluetoothEventRedirector into new
BluetoothEventManager class, deleting the original version. New
version uses a HashMap from action Strings to implementers of the
BluetoothEventManager.Handler interface.
- Created new BluetoothDiscoveryReceiver to update shared preferences
timestamp for Bluetooth discovery start/finish. This is the only event
handling we need to do when the settings app is not visible, so it has
its own receiver entry in AndroidManifest.xml. Edits are written using
QueuedWork.singleThreadExecutor(), which BroadcastReceiver knows about
and will wait for completion, eliminating the need for PendingResult.
- Miscellaneous cleanups to code style and logic for readability.
- Pulled some large switch statement code blocks into new methods.
- Changed all Bluetooth state references to the new BluetoothProfile
constants.
- Changed use of deprecated Notification constructor in
BluetoothPairingRequest to use Notification.Builder.
- Moved Utf8ByteLengthFilter helper function from BluetoothNamePreference
into its own class, and moved test cases into the same package.
- Moved all LocalBluetoothProfileManager functionality related to
specific profiles into new top-level classes (A2dpProfile, etc.), all
implementing the LocalBluetoothProfile interface.
- Moved all UI-related methods from CachedBluetoothDevice into the class
that uses the method, or into the static Utils class for shared methods.

The Bluetooth device name has a maximum length of 248 bytes in UTF-8
encoding. The settings app previously limited the Bluetooth device
name entered by the user based on the number of characters, which is
incorrect when the name includes non-ASCII characters.
Created a new Utf8ByteLengthFilter class for BluetoothNamePreference
which counts UTF-8 bytes instead of Unicode characters, along with
unit tests.
We can move Utf8ByteLengthFilter into the framework in the future
if it would be useful elsewhere in the system or for applications.

Split BluetoothDevice into BluetoothDevice and BluetoothAdapter.
BluetoothAdapter: Represents the local BT adapter. Operations on the local
adapter (start a scan, etc).
BluetoothDevice: Represents a remote BT device. Operations on remote devices
(pair, connect, etc).
