5b94fe6342 stylecontext: Make first property name explicit 
Insist that a first non-NULL property is passed to
gtk_style_context_get().

This is in particular relevant because of dropping the state argument
since GTK3, and code like
  gtk_style_context_get (context, state, "font", &font);
would keep compiling without warnings without this change.

83fb7a649f css: Merge GtkStyleProviderPrivate into GtkStyleProvider 
This is just lots of renaming.

The interface remains private, so the public API does not change, apart
from removing the definition of the Interface object to avoid
subclassing.

1dbdbecd39 gtkstylecontext: Clarify memory allocation behaviour of getters

2e921691d9 Redo CSS style printing 
Drop the custom style printing implementation in gtkcssnode.c and
instead reuse the existing gtk_css_style_print function, extending
it a bit to suit our needs.

Instead of computing values, just recognize initial values by
having no CSS section. Also do away with the show-initial flag, and
just always filter out initial values. The flag can come back when
it is needed.

fe51ac273c stylecontext: Change fallback behavior on state mismatch 
For functions that take state flags as an argument we need to special
case the situation where the passed in flags don't match the current
state.

Previously we would create a copy of the style info, change its state
and do the lookup from there.

Now that GtkCssNode has replaced style infos, this doesn't work as well
anymore as copying a GtkCssNode is not possible.
However, unike style infos, GtkCssNodes are instant-apply, so we don't
need to copy anymore, we can just change the state of the node.

This causes some invalidations to be queued, but we can take that
performance hit as this is fallback code.

637a4bda5c stylecontext: Get rid of stylecontext argument 
... to a bunch of functions.

This requires a tiny change to the heuristics for the style cache - we
now cache styles when they have the same style provider as their parent
instead of when they have the default provider - but that change doesn't
have any effect in practice.

a589f98821 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.

6f99a3cdb0 stylecontext: Change arguments for build_properties 
Instead of passing the style declaration, take the node's style
declaration. Add arguments to allow overriding the state for the one
case where this didn't work.
