The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.
The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

A surface can get destroyed while a shell grab is active, which can
for example happen if the command running in weston-terminal exits.
When a surface gets destroyed, grab->shsurf is reset to NULL by
destroy_shell_grab_shsurf(), but otherwise the grab remains active and
its callbacks continue to be called. Thus, dereferencing grab->shsurf
in a callback without checking it for NULL first can lead to undefined
behavior, including crashes.
Several functions were already properly checking grab->shsurf for NULL,
move_grab_motion() being one example. Others, however, were not, which
is what this commit fixes.

Changing the focused surface did remove the surface_destroy_listener from the wl_signal list,
but destroying the focus state did not. As a result, sometimes the same listener would be added
to two surfaces, which would join their wl_signal lists together, which would cause infinite
loops and use-after-frees when closing desktop surfaces.
This crash was happening when *releasing* a pointer button on a window
that was being resized and got destroyed during the grab.
[@daniels: Cosmetic fixes; apply same fix to grab cancel.]
Use the proper weston_compositor_exit API instead of wl_display_terminate() to
allow the compositor main to prepare for exit, and most importantly to set the
exit error code as appropriate.
I have some brokenness in my test suite running, and weston-desktop-shell was
crashing at start, yet the tests did not notice. With this patch, the tests

Avoid crashes related to get_shell_surface returning NULL.
Surfaces are already allowed to be neither focus nor shell in
e.g. focus_state_surface_destroy.
This allows to possibility to specify where to look for the executable
but also simplifies the need of having to pass either BINDIR/LIBEXECDIR
for retrieving full-path of the executable.

Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.

Collect the fallback definitions of static_assert() from desktop-shell
and the test shell, and move them to helpers.h. This allows code
throughout the tree to use static_assert() for build-time assertions,
where it is supported by the compiler.
As GCC goes out of its way to only add static_assert() when C11 has been
explicitly requested - which we don't do - make sure to use the more
widely available _Static_assert() if that is provided.
This will be used in future patches to ensure two array lengths don't go

This is a tentative crash fix for a case where there are no

Let get_output_work_area() return a zero area if the given output is
NULL. If there is no output, there is no area. Unfortunately we cannot
return "no position" but have to use 0,0 instead.
In send_configure_for_surface(), this causes a maximized surface to
receive width=0 and height=0 in the configure event, which means the
client is free to choose the size. There is no correct size to send for
maximizing for no output.
In constrain_position(), this has no effect. The interactive move of a
surface is restricted to not go below the panel, so even if a user
managed to move a surface without an output, it just prevents the
surface moving beyond y=0.
In weston_view_set_initial_position(), get_output_work_area() will not
be called with NULL output anyway.
In set_maximized_position(), this makes it behave as if the output was
at 0,0 which is the default position of the first output.

This is the start of separating weston-the-compositor source files from
libweston source files.
This is moving all the files related to the 'weston' binary. Also the
CMS and systemd plugins are moved.
xwayland plugin is not moved, because it will be turned into a
libweston feature.
To avoid breaking the build, #includes for weston.h are fixed to use
compositor/weston.h. This serves as a reminder that such files may need
further attention: moving to the right directory, or maybe using the

On client destruction, the shell object may be destroyed before the
shell surface objects. If this happens to two surfaces of the same
client, and one surface being destroyed results in the focus being
switched to the other, this would trigger a ping event.
The ping event sending function relies on having a valid owner, and if
the shell would be destoryed prior to the shell surface, we'd crash in
this function.
Solve this by unsetting the owner pointer when the shell client goes
away and early out in the ping event sending function if the owner is
gone.

Looking at the first of these, unbind_input_panel() gets called when the
text-backend destroys its helper client which has bound to input_panel
interface. This happens after the shell's destroy_signal callback has
been called, so the shell has already been freed.
The other two errors come from
wl_list_remove(&input_panel_surface->link);
which has gone stale when the shell was destroyed
(shell->input_panel.surfaces list).
Rather than creating even more destroy listeners and hooking them up in
spaghetti, modify text-backend to not hook up to the compositor destroy
signal. Instead, make it the text_backend_init() callers' responsibility
to also call text_backend_destroy() appropriately, before the shell goes
away.
This fixed all the above Valgrind errors, and avoid a crash with
ivi-shell when exiting Weston.
Also using desktop-shell exhibited similar Valgrind errors which are
fixed by this patch, but those didn't happen to cause any crashes AFAIK.

This does not affect Weston's or desktop-shells ability to put screens
to sleep after inactivity. The inactivity timer continues to operate as
before. Also screen locking is unaffected.

Do not use a black blanket surface when the startup animation is
specified to be "none". This is the final fix needed to make the
screenshot test deterministic and independent of weston-desktop-shell.
Previously, the black surface would cover all outputs until
weston-desktop-shell signalled ready. Then, depending on the set
animation, either the black surface was immediately removed (none) or a
fade-in started (fade).
Now, when there is no black surface at all for "none", the compositor
will show garbage until weston-desktop-shell gets everything up. This
may be undesireable but works for tests. To have the old "none"
behaviour back, I would propose to add a new startup-animation value
"black" for it.

It's possible for more than one animation to be taking place on a view at
the same time. If one of those animations is the shell's fade out for
dying surfaces, its completion handler will trigger the surface destroy
signal, causing other animations on the animation list to remove themselves.
Since this removal occurs during the linked list walk, the compositor may
crash.
We move the actual surface destruction into an idle handler to avoid this.

Weston has sent the first 'resizing' configure event with width=height=0.
But resizing to that size doesn't make sense.
Instead, we now send the current width and height of the surface at the beginning
of resizing.
