app ops: New ops, features, and modes

AppOpsService: Add MODE_ASK support to AppOps.

Add support for new mode(MODE_ASK) in AppOpsService to show a permission
dialog box to user to confirm user permission before allowing or ignoring
that operation.

All strict operations (defined in AppOpsManager) are going to be in
MODE_ASK by default.

Operations will be moved to MODE_ALLOWED or MODE_IGNORED according to
user's choice.

AppOps: Add support for whitelist of packages.

By default AppOps gives MODE_ASK permission to all strict operations.
This can degrade user experience for pre-installed apps.

This change adds support for passing a whitelist XML file to AppOps.
Operations requested by packages listed in whitelist file will be set
to MODE_ALLOWED by default.

User can still go into settings and override permissions of these
operations.

Whitelist XML file should have following format:
Example: whitelist_appops.xml

<whitelist-pkgs>
    <pkg name="com.android.settings"/>
    <pkg name="com.android.systemui"/>
    .
    .
    .
</whitelist-pkgs>

AppOpsManager: set default mode for sms write operation to MODE_ALLOWED.

The default mode for sms write operation is set to
MODE_IGNORED, so this was not allowing Bluetooth Map application
to do any write operation of SMS. So set the default mode to
MODE_ALLOWED.
