We can get G_IO_HUP and G_IO_IN at the same time, if the compositor writes
data to us and then closes our connection. Make sure that we dispatch events
always if we have G_IO_IN and then error out if we get G_IO_HUP after that.
This way we don't have to reopen all the time for pure updates,
and we can immediately unlink the shm file to avoid "leaking" them
on improper shutdown.
We now only update surface data after we have painted. Before we painted
in an idle, which meant we might send black data some times if we e.g.
resized the window and had not painted yet. Also, it means we're updating
less often to the daemon, saving resources.
We still have to queue a flush in the idle for non-draw operations,
otherwise e.g. resize of a toplevel will never be flushed if the clock
is frozen (e.g. during toplevel resize).
We don't want to update the window size on configure event, only
the position, as the size is client side controlled. We were
updating to an old size during resizes which causes us to send
surfaces of the wrong size to the daemon.
The cursor buffer is only non-null when a cursor is created from pixbuf,
so it is not necessary to keep track of whether to free this buffer on
finalize.
By keeping a pointer to the wl_cursor struct in GdkWaylandCursor, it is
no longer necessary to duplicate cursor data (width, height, hotspots,
etc.) between wl_cursor and GdkWaylandCursor.
Instead of maintaining the init refcount in regular event handlers that can
fire in case of hotplug or mode changes, use a dedicated sync callback
to wait for roundtrips.
If a window is overlapped by a layered (i.e. partially transparent)
window then that region will not disappear from the native window clip
region. This lets us handle compositing multiple layers of windows.
For native subwindows this doesn't really work. For them we apply the
clip region as a shape to the native window which lets us have client
side windows overlapping the native window. However, with the addition
of the layered stuff the "overlapped-by-alpha-csw" part got broken, as
this area is not removed from the clip region of the native window.
We fix this by also removing the layered area when applying the shape.
This means alpha and alpha backgrounds don't work over native windows,
but there is not much to do about that.

The global_removal argument is the _name_ of the object.
We were comparing it to the _object id_ of the object.
To fix this, store the name at the time the object is bound.
We need to be a bit more careful when updating the screen
size - the code that was there would not do the right thing
if e.g. the width of one monitor was reduced.
We use a ref-count mechanism to track whether parts of the init sequence
still needs round trips to receive remaining initial state. Typically
we need a couple of roundtrips total to get the global list, then the
input and output configurations, but with the ref-count we avoid making
global assumptions like that.

Allow to set a GdkWindow to use a custom surface instead of a
wl_shell_surface. It allows to register the surface as a custom type
with some Wayland interface.

The GDK model for keymaps expects the keymap object to stay
around and emit a ::keys-changed signal. So, do that. This
should make layout changes work, but it remains untested since
weston does not support layout changes at runtime.
At the same time, plug a memory leak where GdkWaylandKeymap
forgot to free its xkb objects in finalize.

For introspection scanning which ends up calling class_init() which in
turn calls into the keybindings code, we can just use the fallback
keyval conversion code.

With this commit, we pick up xft settings from GSettings
as well. Among other things, this makes the Large Text
setting work. Still to do: pick up fontconfig changes without
having all clients use up inotify watches for all font
directories.
Add GInitable interface with a default implementation that always
succeeds. This allows backends to override the GInitable implementation
and add their own checks to determine if the backend can be loaded. If
a backend cannot be loaded, GDK can attempt to load the next available
backend.
Since backends may need to read any relevant options (such as the
display flag) to determine if they can be created successfully, this
patch also removes calls that attempt to create the display manager
before the options have been parsed.

The check for GDK_CURSOR_IS_PIXMAP was ineffective, since _all_
cursors have this type, from the looks of it. Instead, store
buffer ownership information separately.
