Previously, the restart command hardcoded "mutter" as the binary name.
This commit changes it to use g_get_prgname() which has a better chance
of being correct (and it does fix session saving for gnome-shell).
Now that mutter is a library, it might be more correct (but also
much higher overhead) to add api for setting these things from
the outside.

An ARGB window with a frame is likely something like a transparent
terminal. It looks awful (and breaks transparency) to draw a big
opaque black shadow under the window, so clip out the region under
the terminal from the shadow we draw.
Add meta_window_get_frame_bounds() to get a cairo region for the
outer bounds of the frame of a window, and modify the frame handling
code to notice changes to the frame shape and discard a cached
region. meta_frames_apply_shapes() is refactored so we can extract
meta_frames_get_frame_bounds() from it.

It's useful to get frame shapes and manipulate them within Mutter, for
example so that the compositor can use them to clip drawing.
For this, we'll need the regions as cairo regions not X regions, so
convert frame shaping code to work in terms of cairo_region_t.

Using MetaWindowActor.opacity for _NET_WM_WINDOW_OPACITY makes it
difficult to implement effects like fading a window in on map.
Instead, set the opacity on the MetaShadedTexture child and use
it when drawing the shadow.
Since the check MetaWindowGroup does on meta_actor_get_paint_opacity()
no longer covers this, we need to handle the opacity in
meta_window_actor_get_obscured_region() explicitly.

If a window can not be tiled, e.g. due to its minimum size hints,
dragging away from the top after activating the maximize tile preview
does not cancel the maximization request, the only way to do so is by
hitting Escape.
To fix, reset the tiling state in the maximize-tile code path as
well if necessary.

Apparently the "fox" toolkit doesn't set WM_CLIENT_MACHINE; while we
could do gymnastics to attempt to figure this out (talk to the X
server?), better to just default to FALSE.

Since appears-focus only propagates up from modal dialogs, if an
application removed the modal hint from a dialog before destroying it,
then its parent would be left with a stray reference to it in
attached_focus_window, causing it to be permanently appears-focused.
The obvious fix, calling meta_window_propagate_focus_appearance() when
the modal hint is removed, tends to cause noticeable flashing, because
the window will get drawn unfocused and then focused again.
So instead we just change meta_window_propagate_focus_appearance() to
check the window type only when focusing in, not when focusing out.
This would also cause flashing, but in this case we can avoid it by
not notifying the change in appears-focus on the parent window if it
is the expected_focus_window (which it will be by this point). (This
does mean though that if something weird happens and the window
doesn't end up becoming the focus window, it won't get redrawn
unfocused until something else forces it to.)
https://bugzilla.gnome.org/show_bug.cgi?id=647613
We need to redraw a window's shadow any time the value of
meta_window_appears_focused() changes. So make that into a property so
we can get notifications on it.

This is necessary for gnome-shell to know whether it should try to
replace the org.gnome.Shell DBus name.
Note: We can't just #include <meta/util.h> because it #defines '_'
at least which obviously conflicts with core gettext. We should
un-export util.h or fix it.
