The position child property is problematic, since it
requires us to emit notification for all children when
inserting a child early in the list of children.
Remove the property from all ui files.
The tree is not needed to walk around the nodes.
It is however still needed for anything that requires modifying the
tree.
There is no immediate benefit in changing this API, but there might be
situations in the future where we can avoid looking up the tree when we
just want to check some details about the node.
Using an empty `configuration_data` object to copy a configuration file
is deprecated since Meson 0.47 (released July 2018); the equivalent
behaviour is available by using `copy: true`.
The executable is called autotestkeywords, so we shouldn't try to run
an executable named keywords. Also rename the metadata file to match.

The installed-tests are now namespaced as gtk-4.0 to avoid colliding
with GTK+ 3, but these files weren't updated.

After removing elements, there were a few cases where the tree wasn't
properly balanced which could further down violate assumptions about the
layout.
Attached is the original testcase that triggered it. I didn't bother
simplifying it.
This model just takes an object and a property name and recursively
looks it up. In particular, I want it for:
widget, widget.parent, widget.parent.parent, ...
This patch does multiple things:
1. Add a custom persistent per-row object.
2. Move all per-row API to that object. This means notifications are now
possible.
3. Add a "passthrough" construct-only property to the TreeListModel that
influences if the model returns these new object or passes through
the ones from the model.
This greatly simplifies the code needed to be written for widgetry,
because one can just connect the per-row object to the expanders that
expand and collapse rows.
As an added power feature, these objects can also be passed through
further models (like filter models).
It also adds kind of a hack to Adwaita to make the test look neat.
The intention of this check was to skip the keyword
test if no c++ compiler is found. But the meson
docs say that add_languages() will abort unless we
pass required: false.
It looks like this got dropped during the move from autotools and never
restored. I can see why, since making it work wasn't a hugely fun task!
Notes on some less then obvious details:
* PlacesSidebar is private now and didn't seem to be to be particularly
easy to adapt to, so this moves to checking for it by name, not TYPE.
I couldn't find a (fast) better way; if you know how, please clean up
* added 2 casts to avoid warnings from the new type-propagating ref()
* GdkClipboard and GdkContentProvider need some properties dodged
* GtkToolItemGroup is gone
* fixed indentation and used TypeName:property-name syntax in a print()
The comment above explains neatly why subclassing GtkButton for
GtkColorButton was a bad idea. Nowadays it's a GtkWidget subclass
containing a GtkButton so let's remove the special case here.
