The struct wayland_input objects tracking the outer compositor's
wl_seats are now properly destroyed when the wayland backend is.

The wl_display_roundtrip call was originally introduced to let the
display_add_seat function wait until a wl_seat.name event was received.
This change replaces the wl_display_roundtrip call with an
asynchronous, nonrecursive equivalent. Now a wl_display.sync callback
is used to delay the final steps of adding a seat until one protocol
roundtrip has occured/the name has been received.

The wayland.c actually include 'xdg-shell-client-protocol.h' instead of
the server one, so fix it. Otherwise, it's possible to get build failure
due to race condition.

Use the real name of the seat instead of calling each seat 'default'. This makes
it easier to identify the current seat in a multi-seat environment.

As observed in #420 (Running Weston under Weston's kiosk shell with
multiple outputs causes the scrollback to go nuts), not
being able to cope with (a correct) resize of the parent surface would
cause the client weston instance to spin forever. If dispatching
failed, just exit.

As an in-flight resize call might cause a call to
wayland_output_destroy_shm_buffers() to go over a list of free_buffers
list. Just initialize the lists before attempting to create the parent
surface to avoid it.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

pixman_renderer_output_create currently takes a flags enum bitmask for
its options. Switch this to using a structure, so we can introduce other

gl_rendererer's output_window_create has a lot of arguments now. Add a
structure for the options to make it more clear what is what.
This is in preparation for adding bare-integer arguments which are ripe
for confusion when passing positional arguments.

In order to start the repaint loop, the Wayland backend tries to damage
the full SHM buffer, but doesn't actually damage the full area if we
have a frame.
Store the buffer's width and height alongside the buffer itself, so we
can damage the full area when required.

We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

In case the base EGLConfig is needed, gl_renderer_display_create() needs to
know it should use EGL_WINDOW_BIT or EGL_PBUFFER_BIT.
The PBUFFER case is added for when the headless backend will grow GL-renderer
support.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.

When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.
This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.
The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

Now that all backends pass in a list of acceptable DRM formats, that is used to
determine if the EGLConfig has an alpha channel or not. Therefore the
opaque_attribs and alpha_attribs are now useless, and we can remove the whole
config_attribs argument from the API.
gl_renderer_get_egl_config() uses an internal attrib list that matches at least
the union of the opaque_attribs and alpha_attribs matches.
Overall, behaviour should remain unchanged.
The new attribute array becomes variable in the future, so it is left
non-const.

Define a specific DRM format for the GL-renderer to render in. It goes through
fuzzy matching in egl-glue.c which ensures we get exactly the number of bits
for each channel, but does not require an exact format match.
This ensures we get the bit depth we expect instead of the first arbitrary
EGLConfig.
This should not change the current behaviour, because Mesa EGL takes care to
order the configs as apps expect.

No caller ever used anything but NULL here, so just use NULL to simplify code.
In fact, no EGL platform defined today even defines any platform attributes
except the X11 platform for choosing a non-default SCREEN.

Depending on system loading, weston-launcher could drop the drm
master access before the compositor and all the clients receive
the notification. In this case, some commit could be sent to the
drm driver too late and get refused with error EACCES.
This error condition is not properly managed and causes weston to
hang.
Change the return type of start_repaint_loop() and repaint_flush()
from void to int, and return 0 on success or -1 if the repaint has
to be cancelled.
In the callers of start_repaint_loop() and repaint_flush() handle
the return value and cancel the repaint when needed.
In backend-drm detect the error EACCES and return -1.
Note: to keep the code cleaner, this change inverts the execution
order between weston_output_schedule_repaint_reset() and
repaint_cancel().
No need to wait for suspend or for any notification; in case the
weston reschedules a repaint, it will get EACCES again.
At resume, damage-all guarantees a complete repaint.
This fix is for atomic modeset only.
Legacy modeset suffers from similar problems, but it is not fixed
by this change. Since drm_pending_state_apply() never returns
error for legacy modeset, this change has no impact on legacy
modeset.
