Previously this setting would just invalidate the whole CSS tree and
thereby hopefully avoid all cache usage.
Now, we actually don't cause extra invalidations anymore, but instead
avoid ever inserting anything into the cache when this setting is set.
This essentially copies the previous cache implementation. With one
caveat: It is now attached to and maintained by the CssNode, not by the
CssStyle.
And this is important because styles may be reused in incompatible
situations which would cause cache collisions and lead to broken CSS in
weird situations.
For now, the split out style cache doesn't cache anything. This is
mostly to make sure that bisections of wrong caching behavior will
bisect down to the commit that actually adds caching.
Use a vertical box gadget for the overall expander, and a
horizontal one for the title row. This lets us get rid of
all the custom allocation code here.
So far, the box gadget is always allocating all children the
full size in the cross axis. This behavior corresponds to the
align-items: stretch behavior in
https://www.w3.org/TR/css-flexbox-1/#align-items-property
This commit implements the other modes described there.
While widgets have halign/valign properties that we can use for
this, the API for inserting gadgets has to change to take an
extra align parameter. All callers have been updated to pass
GTK_ALIGN_FILL, since that corresponds to the previous behavior.

From gtk_widget_path_iter_set_object_name documentation:
"When set, the object name overrides the object type when matching CSS"
Update gtk_widget_path_to_string to match this behaviour.
This is sometimes needed, and calling into actual icon theme
code just for it is confusing - the resulting icon does not
depend on the icon theme at all.

This prevents WM from drawing shadows around tooltip windows,
which, in Adwaita, should have no shadow and are CSD-ish (which means
that tooltip window is larger than it looks, and WM draws the shadow
only on the outside, leaving a gap between the visible tooltip edge and
the shadow).

With Mingw-w64 fstat() can be an inline function that
calls _fstat32() or _fstat64(), depending on some macros.
And if LFS is enabled, fstat() is defined to turn into
_fstat32i64() or _fstat64(). And some/all of the above
might also be macros as well. Side-step all that mess
and excplicitly re-define fstat as _fstat32, which is
guaranteed to use a version of "stat" struct that
has 32-bit size and time fields, which is what we want.
