The Power panel currently installs "info-symbolic"
in /usr/share/icons, which makes this icon to appear
as a pre-installed system icon. This makes app
developers to use this icon in their apps
under that assumption.
Ship this icon as a gresource to fix this.

The "CcPermissionInfobar" widget is a more descriptive way to
communicate that some Settings panel needs authentication in order
to perform certain actions.
This widget doesn't handle the permissions (as in GPermission)
itself. It needs to be binded to an existing instance of GPermission,
and it will react to the permission's state (show when the current
user is not authorized, and hide when the user is authorized).
This is part of a big set of changes that aim to set a consistent
authentication method accross Settings panels.
