title: Xamarin Forms (Core/Portable) creates more Android permissions
body: <p>I have a rather complicated application and just now notice the fact that my app asks for a lot more permissions then I put in the AndroidManifest.xml. In my App.Droid Debug obj map there is a version of the AndroidManifest.xml (this is also the file in the Releases build) which has about 10-15 more permissions then I setup. 
  For example the Accounts permission shows up, but I am not using that function.</p>
  
  <p>Can anyone explain where these come from and how they can be reduced?
  Thanks in advance.</p>
