    AppOpsService: Add MODE_ASK support to AppOps.

    Add support for new mode(MODE_ASK) in AppOpsService to show a permission
    dialog box to user to confirm user permission before allowing or ignoring
    that operation.

    All strict operations (defined in AppOpsManager) are going to be in
    MODE_ASK by default.

    Operations will be moved to MODE_ALLOWED or MODE_IGNORED according to
    user's choice.

    AppOps: track op persistence by name instead of id

    On XML write, include the op name.  On XML read, map
    the name back to op id (if it exists).

    Persistent AppOp state now follows the op name instead
    numeric id.  This allows upgrades between versions of
    android that have different code<>name mappings.

    AppOps: fix deadlock issue when showing dialog

    WindowManagerService need call PowerManagerService to release
    wakelock. The Notifier in PowerManagerService need call AppOpsService
    to notify holding wakelock ops is finished.  Meanwhile, AppOpsService
    may need call WindowManagerService to show dialog. This scenario
    will lead to deadlock issue.
    To move showing dialog action out of lock section to fix this issue.
    Since only UI work is moved out of lock area, it is supposed to be
    safe.

    appops: Add support for SU

    This patch adds support for superuser app-ops control. The end-goal
    is to better prepare superuser for the multi-user experience while
    also replacing the superuser app with existing components.

    appops: Disassociate appops requests from notification broadcasts

    The AppOpsService is essentially a manager for a set of counters
    and permissions. Each operation request has the potential to change
    the state and, as such, access to such state is synchronized.

    We are whitnessing deadlocks caused by the broadcast and, in fact,
    while we want to notify superuser changes eventually, it does not
    have to be synchronous with the app ops request. This patch uses the
    request to schedule the notification on a handler, leaving the locking
    semantics of appops intact.

    Grant wifi, bt, boot_complete, nfc, and data changes for systemui.

    Also remove the bluetooth permission tied to the bluetooth_change op -
    it is not always directly tied to BLUETOOTH or BLUETOOTH_ADMIN, so we
    can't force one there.

    appops: Implement concept of delayedcount.

     High frequency request ops will be delayed until their ignore count
     ceiling is met. This is to mitigate the overloading the main activity
     manager service handler and having watchdog kill our service.

     Google play services likes to share its uid with numerous packages to avoid
     having to grant permissions from the users perspective and thus is the worst
     example of overloading this queue -- so, to not encourage bad behavior,
     we move them to the back of the line. NOTE: these values are magic, and may need
     tuning. Ideally we'd want a ringbuffer or token bucket here to do proper rate
     limiting.

    appops: Respect screen interactivity before creating dialogs.

      If the device's screen is currently off, do not queue ask
      runnables who cannot be interacted with. Since these events
      are gating mechanisms for closing an IPC loop, they need to
      happen when the user is interacting with the device.

      Likewise, on screen off, clear the queue of every op as they
      become unnecessary.
