When the output can't be completely created in the backend (for example
lack of memory), weston_compositor_add_output() is never run. In such
a case output->link is not initialized. Letter, when
weston_output_destroy() is called, application crashes on
wl_list_remove(&output->link).
This problem happens when drm, fbdev, rdp, rpi or wayland backend is
used.
v2: Initialize output->link in weston_output_init() as suggested by
Derek Foreman.

Previously, we blindly created a mode for the output based on surface size
and completely ignoring the output transform. This caused modesets to fail
on outputs that were transformed by 90 or 270 degrees. We should be
swapping the width and the height in this case.

Valgrind has shown that in at least one place (default_grab_pointer_focus)
we're testing uninitialized values coming out of weston_compositor_pick_view.
This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.
This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.
Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them
safely for equality.

When something goes wrong during weston initialization,
weston_compositor_destroy() is executed. It destroys the backend and
then frees compositor memory. Unfortunately RDP backend is not correctly
destroyed. It frees compositor instead of a backend memory. This causes
later a double free error. The easiest way to reproduce a problem is to
run weston with an invalid option.
Additionally some other objects of rdp_backend structure are not
destroyed/freed. The patch fixes both issues.

cms-colord used the weston_compositor destroy signal to
trigger its final colord_module_destroy cleanup, and the
wl_output destroy signal to trigger per output cleanup.
The problem is that the compositor destroy signal gets
emitted before the output destroy signals at compositor
shutdown, colord_module_destroy would free all its
shared data structures and then later on the output
destroy callback would try to access those shared
data structures when handling output destruction
-> Use after free -> Crash, usually with VT switching
dead and thereby an unuseable system requiring a reboot.
Solve this by moving the output destruction handling into
the colord_cms_output_destroy() cleanup function for
colord-cms own hash dictionary of all active outputs.
The output destroy callback just removes the corresponding
output from the dictionary and triggers proper cleanup if
an output is unplugged during runtime. During compositor
shutdown, the dictionary as a whole is released before
releasing all other shared data structures, thereby
triggering cleanup of all remaining outputs.
Tested to fix crashes on x11 and drm backends.
