Commit 58e15865 changed the parameters for udev_get_seat_by_name() to
receive a struct udev_input. However, when this gets called from
create_output_from_connector() during initialization, the input struct
is not yet initialized, leading to a crash. Previously, that function
would take only a pointer to the compositor.
This patch fixes the crash by initializing input before creating any
outputs.

It takes the stride in bytes, not pixels. The bug was hidden when using
va intel-driver 1.2.1 because it would ignore the stride from user and
set the surface state in a wrong way.

The CURSOR_PLANE capability indicates that the backend has a concept of a
cursor plane and can handle a cursor without compositing. This is currently
only advertised by the DRM backend.
The ARBITRARY_MODE flag specifies that the backend is capable of switching to
virtually any resolution. This is currently only advertised in the RDP
backend. While it's a bit buggy right now, it should be capable of this.

Queueing in the Presentation extension requires splitting the viewport
state into buffer state and surface state. To conveniently allow
assigning only one, the other, or both, reorganize the
weston_buffer_viewport structure.

While disable by default, passing --enable-libinput-backend to
./configure switches the input backend in weston's drm, fbdev and rpi
compositing backends to use libinput instead of udev-seat.c, evdev.c and
friends.
When enabled, weston now also depends on libinput >= 0.1.0.

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.
If we VT switch away between picking a cursor surface and actually doing
the pageflip in drm_output_repaint(), we never set output->cursor_view to
NULL. Then we unplug all the input devices and as the last pointer device
goes away we destroy the cursor surface. Then when we switch back, we
call drm_output_set_cursor() with an invalid surface and crashes.

The opaque region is in surface coordinates, which we compare to the
output region, which is in compositor coordinates. For non-primary
outputs, that means that the output region is not located at 0,0 but
something like 1920,0 instead. That means that the output region isn't
contained in the surface opaque region and then we decide we can't scan
out from it.
Instead, compare the surface opaque region to the output region
translated to 0,0.

This patch fixes an issue where Weston using the DRM backend, cannot start
the display. This happens in the following context:
- no video mode is set before weston starts (eg no "/dev/fb" set up)
- weston is not configured with any default video mode (nothing from
weston.ini nor command line)
- the DRM driver provides with a list of supported modes, but none of them
is marked as PREFERRED (which is not a usual case, but it happens)
In that case, according to the current implementation, the DRM compositor
fails to set a video mode.
This fix lets the DRM compositor selects a video mode (the best one of the
list, which is the first) from the ones provided by the driver.

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.
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.
Gather the variables affecting the coordinate transformations between
buffer and local coordinates into a new struct weston_buffer_viewport.
This will be more useful later, when the crop & scale extension is
implemented.
When a renderer switch happens, it is possible that when the surface
state is created, a buffer for the given surface is already available.
In that case, run the attach routine so that the pixel contents are
properly set. Otherwise, it would only be set when a new attach request
is made for that surface.
Also, change the drm backend so that it keeps the buffer reference in
the weston_surface when running with the pixman renderer. The pixman
renderer keeps a reference to it anyway, so it is never released
early.
This makes the renderer transition seamless, without leaving a black
screen as before.
When running with the pixman renderer, the debug binding 'W'
(mod-shift-space W) will cause the compositor to load gl-renderer.so
and start using it instead of the pixman renderer.
This wraps all accesses to an SHM buffer between wl_shm_buffer_begin
and end so that wayland-shm can install a handler for SIGBUS and catch
attempts to pass the compositor a buffer that is too small.
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.
In drm backend, the cursor_surface->plane point to
drm_output->cursor_plane.when this output is removed,
drm_output->cursor_plane is destroyed, butcursor_surface->plane
still point to destroyed plane. So once mouse move to this
cursor_surface and system will repaint this cursor_surface,
segment fault will generate in weston_surface_damage_below() function.
V2:
-set surface->plane to NULL whose plane point to unplugged output,
then change weston_surface_damage_below() to do nothing if
surface->plane is NULL (Kristian)
-set surface->plane to NULL in weston_surface_unmap(),
so that all surfaces that have a non-NULL plane pointer wil be
on compositor->surface_list (Kristian).

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.

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.
If the initial page-flip fails, immediately finish the frame to avoid
being stuck in the given frame. We already do this if we have no fbo
available. Now we do the same if the page-flip fails.
Instead of connecting to weston-launch from launcher-util, we now try to
connect to logind first. If logind provides session-devices, we use them.
If not, we fall back to the old weston-launch facility.
This patch adds a new weston.ini key, gbm-format, to the [core] section.
This new key can be rgb565, xrgb8888 or xrgb2101010, and makes the
compositor use the corresponding GBM format for the framebuffer.
This used to work only for ARGB8888 and XRGB8888 buffers, but this lets
us support pageflipping to any client buffer as long as it matches the
framebuffer format.
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.
EGLInt is not always uint32_t so we need
to make sure we use the right int size for the format.

Currently there is no guarentee that output remove event always happend after
page_flip event on the same output. So if the following situation occur:
first: unplug a output
second: output remove event arrive, output_destrory called adn free output
third: page_flip event arrive on the destroyed output
the segment fault will happpen in page_flip_handler().
This patch add a variable drm_compositor->destroy_pending, if page flip
event is pending when output remove event arrive, output_destroy will be
delayed until page flip finished.

This is only available when running weston directly as root typically for
ssh logins. It's a somewhat destructive option, as it will take over any
existing VT completely, unless there's already an display server running
there.

We'll add the GBM format code as the native visual ID for EGLConfigs
when running on GBM. This patch lets the drm backend pass in the
format code it's using with KMS and make sure we get a confing that
matches. In the future, mesa will add support for 10 bpc configs
which will match the "at least 8 color bits" requirement. By also
matching the native visual ID, we avoid rendering XRGB2101010 into a
XRGB8888 KMS framebuffer.
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.
The struct weston_launcher object will now either handle tty and vt switching
details in-process (when running weston directly as root) or talk to
the weston-launch process.
Previously, vaapi_recorder_frame() would wait until the encoded
contents for a frame is written to the output file descriptor. This
delayed the repainting of the next frame, and affected frame rate
when capturing with high resolutions. Instead, wait only if there is
and attempted to encode two frames at the same time.
Increases framerate from 30 to 60 fps when capturing at 1920x1200 on
my SandryBridge system, although there are periodic slowdowns due to
disk writes.
Another silent regression from the wl_resource opaquify effort. This was
causing our pageflip-to-client-buffer and sprites optimizations to
not kick in.
