Modify the pkg-config check for setbacklight so that failure only
disables building setbacklight, instead of failing the whole configure.

The variable '__environ' seems to be libc implementation specific, and
not avaible on Android.
Use the POSIX standard variable 'environ', which also luckily happens to
be available on Android, which is not POSIX.

evdev.c: In function 'evdev_led_update':

Useless in this case.

Weston's notify_keyboard_focus_*() assume that a keyboard is present, if
they are called. With evdev, there might not always be a keyboard.
Also clean up the variable definition in evdev_notify_keyborad_focus().
I read that function through many times and finally had to grep where
does 'all_keys' come from.

If the sysname of the udev device did not start with "event", the
function returned without unreferencing udev_device.
The function is refactored to have a common exit path that unrefs
udev_device. The return value semantics are not changed.

Move all udev-related and now drm backend specific code into
compositor-drm.c.
This makes evdev.c free of udev and launcher-util, and allows it to be
used on Android.

This makes the generic evdev code (i.e. the functions not relying on
udev) independent of launcher-util too. The aim is to allow re-using the
generic evdev code in the Android backend, where neither udev nor
launcher-util are available.
evdev_input_device_create() signature is changed:
- add the opened device file descriptor
- remove wl_display as unused
Also add a bit of failure logging.

evdev_input_device_destroy() will completement the API of
evdev_input_device_create(), both being independent from udev.
Since the udev-specific device_removed() would only call
evdev_input_device_destroy() and do nothing else, device_remove() calls
are simply replaced with evdev_input_device_destroy().

Since the time values are unsigned integers we can check whether the msec is
smaller than spring->timestamp by checking if the subtraction overflows into a
value greater than half the maximum unsigned integer range (ie. top bit set)
Like how we handle overlays, we split drm_output_set_cursor() into
drm_output_prepare_cursor_surface() that will assign the hw cursor to
a suitable surface and drm_output_set_cursor() that will do the actual
work of updating cursor contents and moving it. This is more in line
with how we handle everything else, and lets us update cursor contents
based on changes to the cursor plane damage.
This works when the cursor content changes but also accumulates
damage when the cursor changes output. In that case we move the
cursor surface to the cursor plane in the new output and
weston_surface_move_to_plane() will generate the damage that triggers
download of sprite contents there.
When we analyze and accumulate damage prior to repainting, we need to
accumulate damage per plane, so that whatever damage a surface
contributes is accumulated in the plane that it's assigned to. Before,
we would always accumulate damge in the primary plane, which caused
repaints in the primary plane whenever a surface in a sprite or
framebuffer was damaged. Eliminating this repaint is a big win for
cases where we pageflip to a client surface or use a sprite overlay.
This also prepares for fixing the missing cursor updates, since we
now track damage to the cursor surface in a dedicated sprite plane.
This backend has not seen even build testing for months, presumably does
not even compile, and is starting to hinder development a little.

This fix xwayland.so that was complaining about jpeg symbols from the

Note that xwayland is not using the jpeg ones, but now that symbols are read
up front we need to link anyway.. or break apart that library.

In the wl_seat conversion, struct wl_touch got fields for the focused
surface and the client resource for the input device being focused.
However, the conversion was incomplete: the old fields
weston_seat::touch_focus* we still used by the event dispatching code,
but the new code never set them. Therefore no touch events were ever
sent.
From weston_seat, remove the fields touch_focus, touch_focus_listener,
touch_focus_resource, and touch_focus_resource_listener. They are
replaced by the corresponding fields and listeners from struct
wl_touch.
While doing this, fix touch_set_focus().
If touch_set_focus() was called first with surface A, and then with
surface B, without being called with NULL in between, it would corrupt
the destroy_signal list. It was equivalent of calling wl_signal_add()
for different signal sources with the same listener without removing in
between.
Now, touch_set_focus() first removes focus and listeners, and then
attempts to assign focus if requested. If the target client has not
subscribed for touch events, the touch focus will now be NULL.
Before this patch, the touch focus was left to the previous surface.
NOTE: this patch depends on the patch "server: add lose_touch_focus()"
for Wayland.

If there is no weston-launcher available, launcher-util.c will fall back
to opening the given file itself. It that case it does not set the
close-on-exec flag, and will presumably leak the file descriptor to
children.
Use O_CLOEXEC on the fallback path, too.

When we hit a segv, it's often the case that we might crash again in
the attempt to clean up. Instead we introduce a minimal restore callback
in the backend abstraction, that shuts down as simply as possible. Then
we can call that from the segv handler, and then to aid debugging, we
raise SIGTRAP in the segv handler. This lets us run gdb on weston from
a different vt, and if we tell gdb
(gdb) handle SIGSEGV nostop
gdb won't stop when the segv happens but let weston clean up and switch vt,
and then stop when SIGTRAP is raised.
It's also possible to just let gdb catch the segv, and then use sysrq+k
followed by manual vt switch to get back.
