This means compositors don't need to call supports() manually and
create() will just return -1 in the failure case as before. This also
means we can deal with the case of eglGetProcAddress returning
non-NULL but not actually being available at runtime.

Create a new function weston_compositor_read_presentation_clock() to
wrap the clock_gettime() call for the Presentation clock.
Reading the presentation clock is never supposed to fail, but if it
does, this will notify about it. I have not seen it fail yet, though.
This prepares for new testing features in the future that might allow
controlling the presentation clock. Right now it is just a convenience
function for clock_gettime().
All presentation clock readers are converted to call this new function
except rpi-backend's rpi_flippipe_update_complete(), because it gets its
clock id via a thread-safe mechanism. There shouldn't be anything really
thread-unsafe in weston_compositor_read_presentation_clock() at the
moment, but might be in the future, and weston core is not expected to
need to be thread-safe.
This is based on the original patch by

The input loop is actually dispatched in the middle of the frame repaint.
When the X11 event results in closing the compositor, this can cause the
current output to be destroyed just prior to trying to process animations
on it.
We fix this by handling the window close event in an idle callback.
NOTE: this requires a patch for wayland that moves the idle handler
dispatch to after epoll_wait in the event loop processing.

Change weston_output_finish_frame() signature so that backends are
required to set the flags, that will be reported on the Presentation
'presented' event. This is meant for output-wide feedback flags. Flags
that vary per wl_surface are subject for the following patch.
All start_repaint_loop functions use the special private flag
PRESENTATION_FEEDBACK_INVALID to mark, that this call of
weston_output_finish_frame() cannot trigger the 'presented' event. If it
does, we now hit an assert, and should then investigate why a fake update
triggered Presentation feedback.
DRM:
Page flip is always vsync'd, and always gets the completion timestamp
from the kernel which should correspond well to hardware. Completion is
triggered by the kernel/hardware.
Vblank handler is only used with the broken planes path, therefore do
not report VSYNC, because we cannot guarantee all the planes updated at
the same time. We cannot set the INVALID, because it would abort the
compositor if the broken planes path was ever used. This is a hack that
will get fixed with nuclear pageflip support in the future.
fbdev:
No vsync, update done by copy, no completion event from hardware, and
completion time is totally fake.
headless:
No real output to update.
RDP:
Guessing that maybe no vsync, fake time, and copy make sense (pixels
sent over network). Also no event that the pixels have been shown?
RPI:
Presumably Dispmanx updates are vsync'd. We get a completion event from
the driver, but need to read the clock ourselves, so the completion time
is somewhat unreliable. Zero-copy flag not implemented though it would
be theoretically possible with EGL clients (zero-copy is a per-surface
flag anyway, so in this patch).
Wayland:
No information how the host compositor is doing updates, so make a safe
guess without assuming vsync or hardware completion event. While we do
get some timestamp from the host compositor, it is not the completion
time. Would need to hook to the Presentation extension of the host
compositor to get more accurate flags.
X11:
No idea about vsync, completion event, or copying. Also the timestamp is
a fake.

The assertion in x11_compositor_find_output() can trigger during normal
shutdown, for example, when moving the mouse while hitting a hotkey to
close the weston window.
Instead we can remove the assert(), return NULL, and discard events
we can't find a destination output for.

Add presentation clock setters that verify the given clock actually
works. Offer an automatic choice of a software fallback clock, when a
backend has to always use clock_gettime() to approximate the
presentation time.
The DRM backend already queried the DRM about the clock id, just let the
DRM backend set the presentation clock from that.
For all other backends which do not get a timestamp from the driver,
call the software clock setter to choose a suitable clock.
Report the chosen clock via presentation.clock_id event to clients.
In finish_frame(), upgrade the argument from uint32_t milliseconds to
struct timespec which can accurately hold the presentation clock values.
This will be needed when weston_output_finish_frame() starts to send out
presentation_feedback.presented events.
While at it, replace gettimeofday() calls with clock_gettime() using the
chosen presentation clock, so we manufacture presentation timestamps
from the presentation clock when the gfx drivers cannot give us a proper
timestamp.
Rpi patch is more verbose due to not having the compositor pointer
available in rpi_flippipe_update_complete(). Explicitly carry the clock
id with flippipe so it is available in the thread.

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.
Currently we destroy the renderer before the outputs are destroyed, but
that sometimes leads to an error since a reference to the renderer is
necessary in order to destroy a gl_renderer_output.
Since destroying the renderer is common among all backends, just move
that call into weston_compositor_shutdown() immediately after the
outputs being destroyed.
Instead of having the backends move the remaining outputs when one is
destroyed, let the core compositor deal with that.

When destroying ouputs, they would sometimes be removed before the call
to weston_output_destory() and sometimes after, depending on the
backend. Now the output is remove withing that function so the behavior
is standard across all backends.
The gl renderer typically repaints everything since we don't have
EGL_buffer_age under X, but the pixman renderer carefully only repaints
damaged regions. So to actually repaint anything with the pixman
renderer, we need to damage the output.

Also make sure backends destroy the renderers before shutting down the
compositor to avoid a double call to weston_binding_destroy().
This is a step towards making renderers switchable during runtime.
If we are about to finish a frame, but a redraw is pending and we let the
compositor redraw, we need to check for errors. If the redraw fails and
the backend cannot schedule a page-flip, we need to finish the frame,
anyway.
All backends except DRM use a timer to schedule frames. Hence, they cannot
fail. But for DRM, we need to be able to handle drmModePageFlip() failures
in case access got revoked.
This fixes a bug where logind+drm caused keyboard input to be missed as we
didn't reenable it after a failed page-flip during deactivation.
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.
This patch implements the notification of clients during mode_switch.
As discussed on IRC, clients are notified of mode_switch only when the
"native" mode is changed and activated. That means that if the native
mode is changed and the compositor had activated a temporary mode for
a fullscreen surface, the clients will be notified only when the native
mode is restored.
The scaling factor is treated the same way as modes.
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]
We changed the protocol to always list modes in physical pixel
units (not scaled). And we removed the scaled mode flag. This
just updates the DRM and X11 compositors and the gl and pixman renderers
to handle this.
