In fact there were two issues:
1. GtkFlowBoxChild with "can-focus"==FALSE should pass the focus
to its child immediately.
2. GtkFlowBox with "can-focus"==FALSE should cease its custom keynav
implementation and fall back to the default GtkContainer behavior
which is more natural.
Thanks to these changes the flow box can act as a better replacement
for GtkGrid and similar containers.

These days exposure happens only on the native windows (generally the
toplevel window) and is propagated down recursively. The expose event
is only useful for backwards compat, and in fact, for double buffered
widgets we totally ignore the event (and non-double buffering breaks
on wayland).
So, by not setting the mask we avoid emitting these events and then
later ignoring them.
We still keep it on eventbox, fixed and layout as these are used
in weird ways that want backwards compat.
If the position of the children is always relative to the box
then we should not take the allocation of the box into account
when flipping the children for RTL text direction.
This patch also removes unused assignments to child_allocation.

We don't want to leak references if the widget created to represent the
item in the model does not have a floating reference — which is usually
what happens in bindings, as they automatically sink references when
creating new instances.
See commit 6e03e7e8 for the similar change in GtkListBox.
gtk_css_node_set_after/before() are now called
gtk_css_node_insert_after/before().
This brings them in line with other similar APIs (ie GtkListStore). And
it allows easier usage of the API (see changes to gtkbox.c).
- gtk_style_context_get_background_color()
- gtk_style_context_get_border_color()
Those functions shouldn't be used anymore, because they don't represent
anything from the CSS styling we support. The background color often
isn't used due to background images and there are actually 4 different
border colors (1 for each side) - if there isn't also a border image in
use.
Replace GTK_TYPE_WIDGET with more specific GTK_TYPE_FLOW_BOX_CHILD
for GtkFlowBox::child-activated. This matches signature of
child_activated slot in class struct.
