Fix 3148496: Initial pass at fragmentizing lockscreen settings.
This converts most of the existing activities to fragments and wraps them in PreferenceActivities so they can be launched as before (e.g. by a DevicePolicyManager) Upload after sync/rebase. Change-Id: I4f351b75d9fca0498bcb04b4e11ff3b70765a4ba
