Add BluetoothDebug.apk for testing and debugging Bluetooth.

Currently it just registers a receiver for all Bluetooth intents,
and prints them to logcat. For example:

BTDEBUG : a.b.device.a.FOUND
BTDEBUG : 	a.b.device.e.DEVICE = 00:18:13:F2:CC:33
BTDEBUG : 	a.b.device.e.RSSI = -35
BTDEBUG : 	a.b.device.e.CLASS = 200404
BTDEBUG : a.b.adapter.a.DISCOVERY_FINISHED
BTDEBUG : a.b.device.a.BOND_STATE_CHANGED
BTDEBUG : 	a.b.device.e.DEVICE = 00:18:13:F2:CC:33
BTDEBUG : 	a.b.device.e.BOND_STATE = 11
BTDEBUG : 	a.b.device.e.PREVIOUS_BOND_STATE = 10
BTDEBUG : a.b.device.a.ACL_CONNECTED
BTDEBUG : 	a.b.device.e.DEVICE = 00:18:13:F2:CC:33
BTDEBUG : a.b.device.a.NAME_CHANGED
BTDEBUG : 	a.b.device.e.DEVICE = 00:18:13:F2:CC:33
BTDEBUG : 	a.b.device.e.NAME = "HBH-IV840"

This application is built by default, but is not installed. Use

mmm development/apps/BluetoothDebug
adb install -r $OUT/system/app/BluetoothDebug.apk

to install it. Logging will begin immediately.
