Allow multiple emulated storages at the same time.

Only do multiuser mapping for primary emulated storage as per google docs.
Allow all non-primary emulated storage to have id other than 0 so that
it could be distinguished from the primary volume.

Don't enable GPS if the requesting app is blacklisted.

This is transparent to the app, it just sees no location callbacks as
before. It just avoids the additional unneeded battery drain.

Frameworks: privacy guard fix UI freeze

randomly sometimes the complete UI freezes when toggle
privacy guard. Move out the forcekill from syncronized to
fix it so that it kills the app when all threads are open
and they can react to the forcekill which cannot result then in unknown states

cheers
