This was missing and causing some problems with GIR compilation for the
UI library.

Philip Withnall 1f3f0a4560 libmalcontent-ui: Move widgets over from malcontent-control
They need to be re-used in gnome-initial-setup. The other widgets which
remain in malcontent-control don’t need to be used in g-i-s so can stay
where they are for now. They might move across to libmalcontent-ui later
if there’s a need for it.

Philip Withnall 3289a37317 libmalcontent-ui: Add initial skeleton for separate UI library
Moving the widgets out of malcontent-control means they can be reused in
other projects. In particular, I’m interested in reusing them in
gnome-initial-setup.

The new library will not build yet, but this introduces all the build
framework necessary for moving the source files over.

Philip Withnall 2a3f0fd741 libmalcontent: Rework pkg-config file generation
Meson 0.49 has matured its pkg-config file generation a little, and the
API has subtly changed. The main library we’re building a pkg-config
file for is now passed as the first argument; and all dependencies can
be passed to `libraries`/`libraries_private`. Any dependencies which
provide pkg-config files will automatically be moved into the pkg-config
file’s `Requires`/`Requires.private` sections.

See https://mesonbuild.com/Pkgconfig-module.html#implicit-dependencies

This bumps our Meson dependency to ≥ 0.49.0.

Philip Withnall 4054913dc2 malcontent-control: Fix losing user changes when apps are installed
If the user has the restrict applications dialogue open and has made
some changes, then installs/uninstalls a flatpak (for example) from
gnome-software in another window, then the list of apps in the restrict
applications dialogue will be reloaded and the user’s changes will be
lost.

Prevent that by not reloading when the set of installed apps changes.
This is not a long-term solution: ideally we’d diff the changes against
the list of apps in the restrict applications dialogue and only update
what’s changed.

Philip Withnall 695ee10235 malcontent-control: Fix use-after-free when closing
Sometimes, when closing the application,
`flush_update_blacklisted_apps()` would be called after
`MctRestrictApplicationsSelector` had been destroyed, leading to a
critical.

This was because the `MctRestrictApplicationsDialog` was being disposed
early due to its `destroy-with-parent` property being set. The dispose
function of `MctUserControls` was run several times due to GTK calling
`g_object_run_dispose()`, and the critical would be emitted the second
time.

Make the dispose function’s call to `flush_update_blacklisted_apps()` be
safe for multiple dispose calls, and ensure the dialog isn’t destroyed
too early.

Philip Withnall bffab0942f malcontent-control: Move the app restrictions into a separate dialogue
Rather than having a scrollable listbox within a scrollable list of
widgets, move the listbox out to a separate dialogue.

This involves separating out all the code to query the apps, to get and
to set the app filter, from `MctUserControls` out into the new
`MctRestrictApplicationsSelector`. Most of it is unchanged, aside from
its interaction with the filter: the filter is now provided to the
widget by the calling code, rather than being queried by the widget
itself. The widget’s status can be queried into an
`MctAppFilterBuilder`, rather than being used to set the app filter
directly.

This commit redesigns the appearance of the relevant widgets in the main
window so that they follow the new list-box-like visual design. A
following commit will apply similar changes to the other widgest in the
main screen.

Philip Withnall 0e22ad7861 malcontent-control: Use g_signal_connect_object() when we don’t hold ref
The application doesn’t hold a ref to some of the widgets it holds a
pointer to, since their ownership is controlled by the main window. The
main window’s lifecycle is controlled by the application, but its
dispose cycle runs at a slightly different time.

Hence, we should disconnect from the widget signals when we can, but
without holding a strong ref.

Philip Withnall c7f975bb2b malcontent-control: Add initial draft of main interface
This replicates the old interface from Endless’ gnome-control-center,
with no attempt to improve or rework it. That will come later.

It might not work fully.

It allows a user to be selected, and their parental controls to be
changed. It currently doesn’t filter the users.

It supports a simple ‘Loading’ screen, before displaying the main
interface. If loading fails (due to a D-Bus error with accountsservice),
an error page is displayed instead.

Philip Withnall aa6ece8a91 malcontent-control: Add widgets from gnome-control-center
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.

Philip Withnall 876c155efb tests: Add pam_malcontent.so tests
These tests check that the built `pam_malcontent.so` module can be
loaded using `dlopen()` and that it exports the right symbol. This
should mean that PAM can load it and use it.

Unfortunately, we can’t actually run the module, since PAM hard-codes
its configuration path as being in `/etc`, and there seems to be no way
to override that to load a dummy configuration from a test directory. So
the only way to test the PAM module is to use a file system bind mount
to fake `/etc` (which requires privileges); or to actually install it on
your system and integrate it into your real PAM configuration. Neither
of those are acceptable for a unit test.

It might be possible to re-execute a test under `bwrap` (if installed)
to achieve this, bind mounting a dummy `/etc/pam.d/dummy` service file
into the subprocess’ mount namespace, and otherwise bind mounting `/` to
`/`. It would need a mock malcontent D-Bus API to talk to. Something to
experiment with another time.

(See `_pam_init_handlers()` in
https://github.com/linux-pam/linux-pam/blob/master/libpam/pam_handlers.c
for details of how PAM modules are loaded.)
