framework: Privacy Guard

 * Introduce a new privacy feature which allows the user to run an
   application with reduced visibility into his or her personal data.
 * Adds a per-application flag and simple API to determine if this flag
   is enabled for the current or calling process.
 * This flag can be used by content providers to decide if they should
   return a limited/empty dataset.

privacy guard: Use LocationBlacklist for location filtering

 * Google has built a per-package blacklist into the location service.
 * Let's use this to handle Privacy Guard instead of our one-off code
   which has a bunch of edge cases and can leave apps in a weird state.
