Never got SharedPreferences working for this system service. Didn't really need it anyway.
Using a straight up file now.

Don't use hard coded defaults - use build configs instead.
Iface is now ONLY set by config so gservices doesn't need to.

Currently warns if you exceed more than 25% and 2*100%*timeUsed/(timeUsed+totalTime)
The formula means that imagining you've got half of the remaining time that you really have,
we will warn you if you would exceed the quota given your rate so far. It's generous during the
early to mid-life and converges back to the limit as your timeUsed approaches totalTime.

Added ContentObserver to watch relevant Secure Settings.
Also added new policy-change broadcast to let settings know.
Lastly reorged things a bit so that all of our broadcasts are sent at boot so the sticky ones
are populated.
