Data usage multi-user support.

Browse Source 
Switch to storing policy per-user instead of per-app, meaning each
user has control over their own set of apps.  Summarize the usage of
non-current users.  Only allow owner to make changes to overall
network policy.

Hide auto-sync menu when viewing app details.  Search for
MANAGE_NETWORK_USAGE intent across all package names sharing a UID.
