The rationale here is, that this line would create an instance of
gl_renderer_interface in every compilation unit that included
gl-renderer.h. This is not necessary, and it can actually be harmful by
masking the real exported gl_renderer_interface symbol, if you added
another compilation unit to gl-renderer.so, causing a runtime failure in
loading it.
gl-renderer.c already creates the exported symbol.
The gbm-format configuration option can now be specified per-output as
well as in the core config section. If it is not specified it will
default to the format specified in the core section. The
EGL_MESA_configless_context extension is required for this to work. If
this extension is available it will create a context without an
EGLConfig and then it will potentially use a different EGLConfig for
each output.
The gl-renderer interface has been changed so that it takes the EGL
attributes and visual ID in the create_output function as well as in
the create function.
Compiling fbdev backend on RaspberryPi caused the following warning:
compositor-fbdev.c: In function 'fbdev_compositor_create':
compositor-fbdev.c:929:6: warning: passing argument 2 of
'gl_renderer->create' makes integer from pointer without a cast [enabled
by default]
compositor-fbdev.c:929:6: note: expected 'EGLNativeDisplayType' but
argument is of type 'void *'
Fix the definition of EGL_DEFAULT_DISPLAY to match the definition in
EGL/egl.h (of Mesa).

The first advantage of this new API is that it is per-output instead of
global to the gl_renderer instance. This means that different windows can
have different titles, different button states, etc. The new api also uses
four textures (one for each side) instead of one. This allows you to draw
real borders with text and buttons in them instead of a simple image that
gets streached.
Images will be scaled as needed, so the right and left can be one pixel
tall if desired.

The time spent loading EGL and GLES libraries from disk can be a
considerable hit in some embedded use cases. If Weston is compiled
with EGL support, the binary will depend on those libraries, even if
a software renderer is in use.
This patch splits the GL renderer into a separate loadable module,
and moves the dependency on EGL and GLES to it. The backends still
need the EGL headers for the native types and EGLint. The function
load_module() is renamed to weston_load_module() and exported, so
that it can be used by the backends.
The gl renderer interface is changed so that there is only one symbol
that needs to be dlsym()'d. This symbol contains pointers to all the
functions and data necessary to interact with the renderer. As a side
effect, this change simplifies gl-renderer.h a great deal.
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]
Rename print_egl_error_state() to gl_renderer_print_egl_error_state()
and exports it.
Remove the copy of that function from the rpi backend, and call
the exported function instead.

The Android backend provides basic EGL/GLES2 graphics, where everything
is always composited. Overlays are not used. Input is stubbed, therefore
there is no input yet.
This adds the first C++ source file into Weston compositor. The Android
gralloc and fb HAL glue code to the Android EGL library is in C++, and
there is no way to access it from plain C. We have a simple wrapper to
the required C++ class API. Android forces the C++ file name extension
to .cpp.
The android backend is compiled by default. However, all Android
specific calls are protected with #ifdef ANDROID, so it will build also
without Android headers. The binary produced without the Android build
system is useless, but allows build-testing generic Weston changes.
Therefore the android backend is not installed.

weston-launch starts weston and provides mechanism
for weston to set/drop drm master, open a tty,
and read input devices without being root.
Execution is allowed for local-active sessions
or users in the group weston-launch.
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.
