Add `CcCarousel` and `CcAppPermissions` from gnome-control-center and
rename the files. None of the contents of the files have been changed
yet. The files are from git master of gnome-control-center on
2020-01-08.
`carousel.{c,h,ui}` are licensed under GPLv2+, and are copyright 2016
Red Hat, Inc. The original author was Felipe Borges.
`user-controls.{c,h,ui}` are licensed under GPLv3+, and are copyright
2018, 2019 Endless, Inc.
`gs-content-rating.{c,h}` are originally from gnome-software, are
licensed under GPLv2+, and are copyright 2015, 2016 Richard Hughes. He
was also the original author. These files are needed by
`user-controls.{c,h}`.
`user-image.{c,h}` are licensed under GPLv2+ and are copyright 2015, Red
Hat, Inc. The original author was Ondrej Holy.
This code will not stay as copy-paste code for too long. The ultimate
plan is to rework most of the widgets:
• `CcCarousel`: Will be reworked to provide more information about the
screen time usage of each user. It will become a summary widget as
well as a selector.
• `GsContentRating`: Will be abstracted out into libappstream-glib, or
some other suitable library, where its implementation can be shared
between gnome-software and malcontent.
• `CcUserControls`: Will be reworked as the UI of malcontent evolves.
Will also be removed from gnome-control-center once malcontent-control
is released.
• `CcUserImage`: As per `CcCarousel`, this will evolve into a new
widget.
