This adds a test that tries to simulate a simple game loop that would
be like this:
while (1) {
draw_something();
eglSwapBuffers();
}
In this case the test is relying on eglSwapBuffers to throttle to a
sensible frame rate.
The test then verifies that only 2 EGL buffers are used. This is done
via a new request and event in the wayland-test protocol.
Currently this causes 3 buffers to be created because the release
event generated by the swap buffers is not processed by Mesa until it
blocks for the frame complete event in the next swap buffers call, but
that is too late.
This can be fixed in Mesa by issuing a sync request after the swap
buffers and blocking on it before deciding whether to allocate a new
buffer.
This has a couple of additional implications for the internal weston API:
1) weston_view_configure no longer exists. Use weston_view_set_position
instead.
2) The weston_surface.configure callback no longer takes a width and
height. If you need these, surface.width/height are set before
configure is called. If you need to know when the width/height
changes, you must track that yourself.
If the environment variable WESTON_TEST_CLIENT_PATH is not set, do not
quit Weston in the test plugin.
This allows one to start Weston with the test plugin manually, and then
run any tests also manually, while observing Weston's behaviour over
time. This is useful for:
- Running a test multiple times and checking if Weston leaks (e.g. with
Valgrind)
- Running tests manually on a backend that is not x11 or wayland,
especially the backends that require weston-launch, and therefore
cannot be used with the 'make check' machinery.
This change should not affect 'make check' behaviour, because there
WESTON_TEST_CLIENT_PATH is always set.

weston_view_update_transform() will post damage in the old and new
positions of the view and thus make sure we always repaint properly.
In particular, in bug 66133, the test suite moves the surface off
any output and weston_surface_schedule_repaint() in commit fails to
do anything, since the surface is not on any output.
After changing view geometry, we have to either call
weston_compositor_schedule_repaint(), which is what shell.c typically
does, though that repaints all outputs, or call
weston_view_update_transform() to force update the transformation
and queue repaints on affected outputs.

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.

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.

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.

Instead of directly setting the dirty flag on weston_surface geometry,
use a function for that.
This allows us to hook into geometry dirtying in a following patch.
Also add comments to weston_surface fields, whose modification causes
transform state to become outdated.

This way the shell can know when a surface has been unmapped by
checking the value returned by weston_surface_is_mapped(surface).
The configure handlers have now width and height parameters, so
they do not need anymore to check manually the buffer size.
If a surface's buffer is NULL the width and height passed to the
configure are both 0.
Configure is now only called after an attach. The variable
weston_surface.pending.newly_attached is set to 1 on attach, and
after the configure call is reset to 0.
The weston test extension, called weston-test.so, can be loaded
from the "modules" configuration option on the command line
or in the .ini file.
Clients can bind to the "wl_test" interface to interact with
the weston test extension.
