The logic here broke at some point so that we would only update the
input region for non-fullscreen windows. Thus, a fullscreen window would
be stuck with whatever size the most recent non-fullscreen size was.

The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

We get the child position but never use this information here. Just remove it.

the unmap event will be followed by the deletion of the weston_surface,
so the shell_surface will also be deleted by the shell. Having removed
the surface_destroy_listener, the surface_destroy callback doesn't
get called, so reset the value of shsurf here.
Typically we can write it immediately without blocking, so save the overhead
of setting up an fd watch and writing the data in a callback. For the
case where the immediate write doesn't write all data, we fallback and
set up the fd watch as usual.
This patch also consolidates setting up the async write a bit.
We used to destroy the frame window and reparent the client window to
wm_window. That means that we lose the destroy_notify event when the
client window is destroyed later, since we don't select for
substructure_notify on wm_window.
Instead of destroying and reparenting, just unmap the frame window.
Now that we use AC_SYS_LARGEFILE, we need to pull in config.h at least
whereever we use mmap(). Fixes at least the test-suite and simple-shm
on 32 bit systems.
window->x/y is the coordinate of the top-level surface (whether that's
the frame window or an override-redirect window) and the wayland surface
should be placed there, without the t->margin offset.
The coordinate transformation was broken (worked for first output where
output->x/y was 0,0, broke on all other outputs). We can just use
surface->geometry.x/y directly. We can't use the full transformation,
the best we can do is to move the X window to the geometry.x/y location.
Get rid of the static old_sx/sy hack as well.
We only get configure notify for toplevel (frame or override-redirect window)
and those are the cases where we want to update window->x/y. The way the
code worked, we'd exit immeidately in those cases and window->x/y would
not be updated.
We can get a destroy notify for the frame window after we've removed it
from the hash table. This turns into a NULL pointer deref when we look up
the window and try to use it for debugging printout.
Fixes the failing xwayland test case.
This commit sets the version numbers for all added/created objects. The
wl_compositor.create_surface implementation was altered to create a surface
with the same version as the underlying wl_compositor. Since no other
"child interfaces" have version greater than 1, they were all hard-coded to
version 1.

Window contents cannot be assumed to be fully opaque for windows drawn with
a RGBA visual. The optimization of setting a full opaque region is limited to
windows with a color depth != 32.
Because of its links to selection.c and xwayland, a destroy_signal field
was also added to wl_data_source. Before selection.c and xwayland were
manually initializing the resource.destroy_signal field so that it could be
used without a valid resource.

When printing debug information about atoms, the XWM would crash if the X
server failed to respond to a request about atom names. In practice this
occurred when the server itself crashed, e.g. when starting mplayer with the
"xv" vo.
This is the first in what will be a series of weston patches to convert
instances of wl_resource to pointers so we can make wl_resource opaque.
This patch handles weston_surface and should be the most invasive of the
entire series. I am sending this one out ahead of the rest for review.
Specifically, my machine is not set up to build XWayland so I have no
ability to test it fully. Could someone please test with XWayland and let
me know if this causes problems?
Because a surface may be created from XWayland, the resource may not always
exist. Therefore, a destroy signal was added to weston_surface and
everything used to listen to surface->resource.destroy_signal now listens
to surface->destroy_signal.
AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar
macros to expose the largest extent of functionality supported by the
underlying system. This is required since these macros are often
limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually
on some systems hide declarations which are not part of the X/Open spec.
Since this goes into config.h rather than the command line, ensure all
source is consistently including config.h before anything else,
including system libraries. This doesn't need to be guarded by a
HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org
modular transition.

[pq: rebased and converted more files]
This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config. This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.
To avoid a TOCTOU race the config file is actually open()ed during the
search. Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.

struct weston_surface is now the only surface type we have (in core, shell.c
has shell_surface, of course). A lot of code gets simpler and we never
have to try to guess whether an API takes a wl_surface or a weston_surface.
