The keyboard focus listener, caps changed and pointer focus listener
were missing when destroying the seat. These are necessary to avoid
using weston_desktop object even if it was destroyed, which happens due
to a focus out event and ultimately handled by the keyboard focus notify
callback.
Once the seats are destroyed (and implictly the focus handlers) we're
safe to destroy weston_desktop object as well.

Follow-up from commit 'desktop-shell: don't run fade animation if
compositor is inactive' where the reference was dropped directly,
instead of using weston_surface_destroy().
Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
When a window is closed, Weston will, by default, run a fade out animation and
defer destroying the underlying surface until it completes. However, if the
compositor is sleeping, and therefore not rendering any frames, this animation
will *never* complete. Therefore, if windows are repeatedly created and
destroyed while in sleep mode, these surfaces will keep accumulating, and since
the buffers attached to them may be backed by an fd, eventually the ulimit will
be reached resulting in a potential crash or other errors.
This can be demonstrated repeatedly launching and killing an X11 application
with Xwayland running.
while true; do xterm & pid=$!; sleep 0.5; kill $pid; done
As soon as the compositor goes to sleep, one can observe a steadily growing
list of dmabufs in the output of lsof.
As a fix, desktop_surface_removed should check whether the compositor is active
before kicking off the fade animation. If it is not, it should instead drop the
extra reference taken in desktop_surface_committed and then destroy the surface
immediately.

still allows to activate the parent. This can be problematic with
modal dialogs such as message boxes which then are hidden behind the
main window, which might be non-responsive to inputs at this this
point.
The protocol specifies set_parent as follows: "Set the 'parent' of
this surface. This surface should be stacked above the parent surface
and all other ancestor surfaces."

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

A surface can get destroyed while a shell grab is active, which can
for example happen if the command running in weston-terminal exits.
When a surface gets destroyed, grab->shsurf is reset to NULL by
destroy_shell_grab_shsurf(), but otherwise the grab remains active and
its callbacks continue to be called. Thus, dereferencing grab->shsurf
in a callback without checking it for NULL first can lead to undefined
behavior, including crashes.
Several functions were already properly checking grab->shsurf for NULL,
move_grab_motion() being one example. Others, however, were not, which
is what this commit fixes.

Changing the focused surface did remove the surface_destroy_listener from the wl_signal list,
but destroying the focus state did not. As a result, sometimes the same listener would be added
to two surfaces, which would join their wl_signal lists together, which would cause infinite
loops and use-after-frees when closing desktop surfaces.
This crash was happening when *releasing* a pointer button on a window
that was being resized and got destroyed during the grab.
[@daniels: Cosmetic fixes; apply same fix to grab cancel.]
Use the proper weston_compositor_exit API instead of wl_display_terminate() to
allow the compositor main to prepare for exit, and most importantly to set the
exit error code as appropriate.

Let get_output_work_area() return a zero area if the given output is
NULL. If there is no output, there is no area. Unfortunately we cannot
return "no position" but have to use 0,0 instead.
In send_configure_for_surface(), this causes a maximized surface to
receive width=0 and height=0 in the configure event, which means the
client is free to choose the size. There is no correct size to send for
maximizing for no output.
In constrain_position(), this has no effect. The interactive move of a
surface is restricted to not go below the panel, so even if a user
managed to move a surface without an output, it just prevents the
surface moving beyond y=0.
In weston_view_set_initial_position(), get_output_work_area() will not
be called with NULL output anyway.
In set_maximized_position(), this makes it behave as if the output was
at 0,0 which is the default position of the first output.

use a new method, weston_view_set_output(). The method can
set up an output destroy listener to make sure that views
do not have stale output pointers.
Without this patch it is possible to end up in a scenario
where, e.g. configure_static_view() accesses memory that
has already been freed. The scenario can be provoked by
repeatedly plugging and unplugging a display. The faulty
memory accesses are reported by valgrind.

The user data of a wl_resource representing a wl_output protocol object
used to be a pointer to weston_output. Now that weston_output is being
split, wl_output more accurately refers to weston_head which is a single
monitor.
Change the wl_output user data to point to weston_head.
weston_output_from_resource() is replaced with
weston_head_from_resource().
This change is not strictly necessary, but architecturally it is the
right thing to do. In the future there might appear the need to refer to
a specific head of a cloned pair, for instance.

/home/pq/git/weston/desktop-shell/shell.c: In function ‘shell_output_destroy_move_layer’:
/home/pq/git/weston/desktop-shell/shell.c:4718:24: warning: unused variable ‘output’ [-Wunused-variable]
struct weston_output *output = data;
Since the data pointer is not used for anything, decided to also set it
to NULL in the caller. This caused another variable to become unused.

If for some reason the helper client weston-desktop-shell would create
more than one panel surface for the same weston_output, this code would
corrupt the surface destroy listener list by adding a link already in
one list into another list.
Instead, do not store the new, redundant panel surface and do not
subscribe to its destruction. Also, tell the helper that the surface is
redundant by configuring it with a 0x0 size, so that we don't waste
memory on a panel that is never used.
(Clone mode is a valid reason why weston-desktop-shell could do that.)

Our case is when the view is the same as output being disabled/disconnected.
There's not need to check the views' output with the output being disabled
because weston_view_assign_output() already changes the output of the view when
the output has been disabled/disconnected hence the check is not needed at all.
The views' output will always be different than the output being disabled.
By the time shell_output_destroy_move_layer() gets called the views' output has
already changed to a "free" output. Tested this by unplugging/disabling the
output on purpose.

There may be race condition between destroying surface and destroying
output. If handle_output_destroy() is called after surface is destroyed,
illegal memory access occurs when surface destroy signals is
unregistered from the panel/background. This patch fixes this issue and
removes unnecessary initialization for panel surface listener.

When a client transitions from maximized to fullscreen to maximized (run
weston-terminal, maximize it, hit f11 twice) we're sending size 0,0 for
the unfullscreen configure, which still has maximized set.
This results in clients correctly picking any size they like, and weston
disconnecting them for it.
Instead, pass the correct maximized size.

Change weston_compositor_get_time to return the current compositor time
as a struct timespec. Also, use clock_gettime (with CLOCK_REALTIME) to
get the time, since it's equivalent to the currently used gettimeofday
call, but returns the data directly in a struct timespec.
This commit is part of a larger effort to transition the Weston codebase
to struct timespec.
