cssnode: Add gtk_css_node_invalidate_style_provider()
...
This function not just invalidates the current node, but also all
children.

cssnode: Change get_style_provider() vfunc
...
Instead of always returning a provider, allow the vfunc to return NULL
to mane "use same provider as parent". This allows a bunch of
optimizations.

cssnode: Implement a way to properly track invalidations

See the comment in gtkcssnodeprivate.h for how this works.

cssnode: Change vfunc
...
This is mainly an attempt to merge the update_style() and validte()
vfuncs. Code is not there yet, but that's the idea.
Also, gtk_css_node_set_style() should not be public. And this gets
closer to that goal, too.

cssnode: Only pass a boolean for parent changes
...
Nobody cares what changed in the parent, so don't track it.

cssstyle: Remove unused optimization
...
After measuring it, I realized the optimization never triggers for
Adwaita and rarely ever triggers for simple themes. So it is not
useful to keep it around.

cssnode: Treat transient nodes as invisible nodes
...
Making transient nodes invisible allows us to remove special cases
without any bad side effects and they continue working just like they
did before.

cssnode: Add visibility concept
...
This allows hiding nodes of invisible widgets.
And that in turn makes sure :nth-child() works as expected.

box: Use CSS nodes instead of widget paths

This is a very simple patch that causes a bunch of overhead. But it
works.

cssnode: Refactor node tree modification code
...
This allows adding more API for it.
It also includes code that tracks modifications and invalidates siblings
and their positions whenever nodes get added or removed.

cssmatcher: Allow widget path matcher to take a node declaration
...
The node declaration has the same functionality as
gtk_css_node_declaration_add_to_widget_path(). So instead of using that
function on a path, you can use the original path and the declaration in
a matcher.

cssnode: Split out a function
...
So far the vfunc is kinda quirky (the path argument is an out argument
for something you have to free when you're done with the matcher), but
I'm about to change that.

cssnode: Change way invalidation is handled
...
Have a queue_validate() vfunc and a dequeue_validate() vfunc that are
called only on root nodes so they can queue a validation on their frame
clocks.

When the style is invalid, redo it.
Make this a vfunc, so the widget nodes can opt out.

cssnode: Implement refcounting
...
The parent refs the child, so gtk_css_node_set_parent() adds/removes a
reference.
We should probably refactor this so that we name the function
parent.add(node) instead of node.set_parent(parent) - makes the
refcounting more clear.

stylecontext: Split out GtkCssNode into own file

The functionality of it is supposed to grow, so better put it in a
custom file early.
This is just a naive split so far, the next patches will split things
further.
