Bluetooth app will indicate BluetoothOppReceiver to receive
device picker intent. But for fix the security issue we
removed the setClassName() method in ag/14111132 to avoid attack.
It causes BluetoothOppReceiver cannot receive the intent.
This CL will compare to calling package name with launch package name.
If they are not equal, the setClassName() will not invoke.

BluetoothPermissionActivity and DevicePickerFragment will send
broadcast to return the result to calling apps. As this broadcast
intent is from Settings with uid 1000, it will be sent to any
protected BroadcastReceivers in the device. It can make an attacker
send broadcast to protected BroadcastReceivers like factory reset intent
(android/com.android.server.MasterClearReceiver) via
BluetoothPermissionActivity or DevicePickerFragment.
This CL will not allow to set package name and class name to avoid
the attacker.

Test: make -j42 RunSettingsRoboTests and use test apk to manually test
to verify factory reset not started and no system UI notification.

The root issue is that CharSequence is an interface.
String implements that interface, however, Spanned class
too which is a rich text format that can store HTML code.
The solution is enforce to use String type which won't include
any HTML function.
Test: Rebuilt apk and see the string without HTML style.

Before this CL, there is a possible phishing attack allowing a malicious
BT device to acquire permissions based on insufficient information
presented to the user in the consent dialog. This could lead to local
escalation of privilege with no additional execution privileges needed.
User interaction is needed for exploitation.
This CL add more prompts presented for users to avoid phishing attacks.
Merge Conflict Notes:
There were a number of entries in strings.xml that did not exist on this
branch. However, as the CL only adds new entries rather than modifying
old ones this should not cause a problem. There were no merge conflicts
in the java files.
