This ensures that all function pointers we do not fill in will be NULL.
I had a crash in the Xwayland test with
https://gitlab.freedesktop.org/wayland/weston/merge_requests/274 without this,
because import_dmabuf was garbage.

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).

This clarifies what is supposed to be the libweston code.
v2: screen-share.c is already in compositor/ instead.

The noop-renderer doesn't read buffer contents, which means bad
buffers go undetected. Thus, read the buffer contents just for
the purpose of triggering SIGBUS (and having the client killed).
Fixes the bad-buffer test when run against the headless backend.

This lets the compositor know the size of the surface as calculated
in weston_surface_set_size_from_buffer(), and fixes a couple of
tests when using the headless backend.

Remove create_surface() and destroy_surface() from the renderer
interface and change the renderers to create surface state on demand
and destroy it using the weston_surface's destroy signal.
Also make sure the surfaces' renderer state is reset to NULL on
destruction.
This is a step towards runtime switchable renderers.
(rpi-renderer changes are only compile-tested)
This commit adds a weston_buffer structure to replace wl_buffer. This way
we can hold onto buffers by just their resource. In order to do this, the
every renderer.attach function has to fill in the weston_buffer.width and
weston_buffer.height fields.

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.

This moves the surface color state into gles2-renderer. To do this it
adds two new weston_renderer functions. create_surface to be able to
create per-surface renderer state, and surface_set_color to set the
color of a surface and changes it to a color surface.
Add a headless backend and a noop renderer, mainly for testing
purposes. Although no rendering is performed with this backend,
this allow some of the code paths inside Weston and shm clients
to be tested without any windowing system or any need for drm
access.
Compositor core does not do anything with udev, so the header is not
needed there. Move the #include into evdev.h, from where it gets used by
compositor-drm.c, too.
Also fix the fallout:
tty.c: In function 'tty_create':
tty.c:143:2: warning: implicit declaration of function 'fstat'

We dont want to receive hotplug events while being inactive.
When getting back active we enumerate all devices and would end up
with two sources for one device that may be hotplugged in the mean time.
This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.
Besides the new header file, there's also a change in the main evdev creation
procedure for a more suggestive name (evdev_input_add_devices ->
evdev_input_create). There's no real functional changes in this commit.
