    Adds an app-ops option for root access.

    Platform-signed apps weren't previously being listed but there are some
    that use root access (FileManager comes to mind).

    So we list all of them, but for platform-signed apps we only show the
    root toggle and none of the permission-based ones.

    Settings: Fix inflate exception on search. Dynamically replace nested fragment.

       When PrivacyGuard is opened, the parent fragment would inflate the layout
       which contained a nested fragment. This is bad behavior. Since we couldn't
       keep track of the fragments lifecycle, the fragment we instantiated during
       inflation would cause an inflate exception if and when we toggled the search
       view within the current context.

       Mitigate the crash by programmatically replacing the fragment after instantiating it once.

    Do not allow privacy guard for core system apps.

    Hide any applications that have the system UID as well as System UI from
    privacy guard. Enabling this on these core apps can have disastrous
    consequences, since many privacy guard authorization requests will queue
    up. This can cause the system process or System UI to be killed when
    they ANR while they wait at the end of a very long queue for the user to authorize them.

    By using privacy guard, you are trusting that the system will control
    and protect these permissions in the first place; there is no need to protect
    the system from itself.

    Settings: Always show Privacy Guard permissions

    Enabling Privacy Guard for an app simply means switching a set of
    operations to MODE_ASK, independently on whether the application
    actually declared those ops (though a permission) or not. The
    framework keeps track only of the ops with a non-default value. As
    consequence, all the ops set by Privacy Guard that aren't declared
    by the app through its manifest are effectively lost when set to
    their default value and the settings won't show them.

    Never hide the Privacy Guard ops to provide a consistent UI.

    AppOpsState: Hide undeclared Privacy Guard OPs

    Since commit f02e0409
    ("Settings: Always show Privacy Guard permissions"), all the Privacy
    Guard OPs are shown independently on whether the application declared
    the associated permission or not. This solved the UI inconsistencies,
    but it's still confusing. Instead of always showing these special OPs,
    hide them, unless unless the application declared the associated
    permission or the OP doesn't have an associated permission.

    Note: if a Privacy Guard OP is not associated to any permission it
    will appear for every application with Privacy Guard enabled,
    bringing back the UI inconsistency solved with f02e0409.
    This doesn't happen with the current set of OPs.
