The tmpdir is used for a wide assortment of things, and
can easily fill up. If it fills then desktop will start
crashing with SIGBUS errors.
This commit changes the shm pool allocation code, to use
memfd_create, instead, so the shared memory files will
be anonymous and not associated with /tmp

(1) Keep priv->text_allocation for the area used by the text
(2) Compute all text coordinates with the help of priv->text_allocation
As a side effect the get_text_area_size and get_frame_size vfuncs are
now unused. If we wanted them back, they should get a single use durig
size_allocate() and then their results should be stored for further
processing.
This complicates refactorings, so remove that feature. It's not used
anywhere and doesn't play well with nodes the way it's implemented.
If we want it back, we can add it back later.
Changing the visibility of child widgets in size-allocate does
not work well with out current allocation and layout machinery.
To avoid the visual fallout, just keep the arrow buttons visible
and only change their sensitivity.

We don't want to let baseline adjustment shift the child
out of the original allocation. This is purely a sanity
measure - in practice, the baseline should always be bigger
than the child_baseline.
We were adjusting the allocation to line up baselines before
calling gtk_widget_size_allocate_with_baseline, but that function
is doing this alignment internally anyway and expects to be given
a 'fill' allocation.
Move the allocation adjustment code down into
gtk_box_gadget_allocate_child where it only affects child gadgets,
not child widgets.
Make the theme follow our documentation for the various .csd and
.ssd style classes: They all go on the window node. For now, just
add the new selector; the old one will be removed when mutter has
been updated.

When measuring children while distributing a given height,
we must measure them for the given width that goes with
the height. Otherwise, things will go wrong if some of the
children do actual width-for-height. This was showing up
as misaligned images in anaconda.

It might have changed (eg. after a row being expanded, and the child
rows revalidated), so just update it here based on the last pointer
position.
Based on a patch by Maxim Reznik <reznikmm@gmail.com>
https://bugzilla.gnome.org/show_bug.cgi?id=760891
The pointer position is queried to properly trigger the prelight
updates on the new row below it. We store the last coordinates
though, and track crossing events to unset these, so it's safe
to just update_prelight() here on these.
Check that non-native window are indeed children of the event window and
only then confirm that they should be drawn.
Fixes Glade thinking that it's okay to have the draw function do
different things depending on what window to draw. (This should really
be fixed in Glade.)
There's no reason to insta-crash when something goes wrong. Just don't
do anything stupid.
Also, remove the SPCIAL_CONTAINER() exception. Every case where special
containers needed this, it is wrong and made containers draw children
multiple times.
