Logic to move phone into security-admin mode

* Create notification to display when syncs fail due to security
* Create psuedo-activity (no UI) to manage device admin state transitions
* Clean up and flesh out SecurityPolicy APIs'
* Add placeholders in EasSyncService showing how to react when policies
    are not met and sync cannot continue.

Note:  There are some STOPSHIP todo's at the top of SecurityPolicy.java.
These should explain any code that you might think is "missing".
