Subject: [PATCH] AI 144257: am: CL 144256 Need to show opt-in screen for
 location collection.   Added a screen to the setup wizard, after login, to
 ask user to   opt-in for location collection.   Added a dialog to Settings
 when user turns on Network location.   Fixed a security permission issue in
 LocationManagerService related   to this change.   Original author: yamasani 
  Merged from: //branches/cupcake/...

Automated import of CL 144257
