Previously, the repositioning logic would iterate the compositor's list
of layers and move the views on those layers. However, that failed in
two different ways: it didn't cover hidden workspaces and crashed when
the display was locked.
This patch changes the logic to explicit iterate over all the layers
owned by the shell. The iteration is done through a helper function,
shell_for_each_layer().

When a fullscreen surface gets the maximized state, the function
reset_surface_type() is called and that causes unset_fullscreen() to be
called. That function would set the value of shsurf->fullscreen_output
to NULL. However, since the surface still has the fullscreen state, it
will be configured as a fullscreen surface again, and an attempt to
access that field would cause the compositor to crash.
Fix the crash by keeping the value of fullscreen_output around after
unset_fullscreen(). This is safe since the value is only used when a
surface has the fullscreen state and is replaced on a new request to
make the surface fullscreen.

The timer was left running after the screensaver was terminated. When
it triggered, a fade out that would in turn cause the screen to be
locked was started. Since that could happen without the compositor
emitting the idle signal, there would be no wake signal to make the
shell show the lock screen, so the system was left unresponsive
until the idle signal actually triggered.

Before commit 2f5faff7f9 when the compositor is locked it would
reset the keyboard focus on all of the seats as part of pushing the
focus_state. This was removed because it now always keeps track of the
focus_state in the workspace instead of waiting until the state is
pushed. However this had the side effect that the active surface would
retain focus when the compositor is locked. This patch just makes it
explicitly set the keyboard focus to NULL on all of the seats when
locking. This will be restored based on the workspace's state when
unlocking.
https://bugs.freedesktop.org/show_bug.cgi?id=73905
The focus_state list on a workspace only contains entries for seats
which have a keyboard focus on that workspace. For workspaces that
have no surfaces the list will be empty. That means that when a
workspace with no surfaces is switched to it would previously leave
the keyboard focus unaffected and you could still type in the surface
on the old workspace.
This patch makes it instead reset the keyboard focus to NULL for seats
without a focus_state. It does this by temporarily stealing the
compositor's list of seats while it iterates the focus_states. After
all of the focus states have been processed any seats remaining in
this temporary list have their focus reset.

Commit c85f1d45 caused the move of an unresponsive surface to be no
longer possible, since the grabbed flag would prevent the move grab
to start while the busy grab was still active.
The shell_destroy_shell_surface function only set the backing resource to
NULL, leaving an unusable surface in the popup_grab list until the surface's
fading animation finished and it could be freed. This caused a segfault if
the shell tried to forcibly break the grab during that time interval due to
the compositor losing the keyboard focus.

When a client calls the input panel (weston-keyboard e.g.)
and then goes fullscreen, the panel will not be hidden
anymore.

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.

This provides an example of keeping a weston_surface alive after the client
destroys it. We install a destroy listener for the resource, so that we'll
be notifified when the client destroys it. Then we increase the weston_surface
refcount so that we keep the surface and initiate an animation. When
the animation finishes we can finally destroy the surface.
Rather than require that the client implement two methods for every state,
simply have one global request, change_state, and one global event,
request_change_state.
This was always a little iffy. At least it could have been a signal,
but we now have focus signal, so lets just use that. We lose
the ability to detect unresponsive clients at key event time, but we
could add that back by adding a key_signal.
Use a static assert to catch mismatch between implementation and
interface version. Fix window.c to not use XDG_SHELL_VERSION_CURRENT,
which will fail to catch version mismatches. The implementation version
must updated manually when the implementation is updated to use the new
interface.
Responsivenes is a per-client thing so we move the ping/pong functionality
to xdg_shell. Having this per-window was carries over from the EWMH
protocol, where the WM has no other way to do this. In wayland, the
compositor can directly ping the client that owns the surface.
This is used to figure out the size of "invisible" decorations, which we'll
use to better know the visible extents of the surface, which we can use for
constraining, titlebars, and more.
Remove the listener for output destroy from weston_view and instead
iterate views owned by the shell in its own output destroy listener.
This simplifies the code a bit since keeping the view listening for the
destroy on the right output was a bit complicated. This also removes the
function pointer output_destroyed from weston_view. The only user for it
was desktop shell, but now this is all handled in shell.c.
Since that signal is per output, it is necessary to track in which
output a view is in so that the signal is handled properly.
Instead, add a compositor wide output moved signal, that is handled by
the shell. The shell iterates over the layers it owns to move views
appropriately.
When xwayland creates a shell surface we don't have a resource. The
recently added shell_surface_is_wl_shell/xdg_surface() tests don't
handle that very well.
For now, we assume that a surface without a resource is created from
xwayland and is a wl_shell surface. We'll want to modify that to be a
xdg surface eventually, but for now this stops weston from crashing.
Since commit 9046d2, when destroying a surface, we remove all the
links from its children. But when the child surfaces are destroyed,
those links will be removed again, but since they were not properly
initialized, weston will crash.
Call shell_surface_set_parent instead which removes the link and
sets parent while also initializing the link, thus avoiding this
crash.
We don't have focus-follows-mouse, so it makes more sense to
maximize or fullscreen the surface that has the keyboard focus,
not the one behind the pointer.
We have to move the surface destroy listener around as we track the
currently focused surface. Introduce a helper function,
focus_state_set_focus() for this and use throughout.

Various functions that operate on a weston_surface assume the
surface has a shell_surface. That is, they unconditionally
deref the get_shell_surface() result. Hence, if for some reason
the call to get_shell_surface() returned NULL to those functions then
a segmentation fault would occur and the program would crash. So,
adding an assert(...) on the get_shell_surface() return value adds an
extra sanity check and does not change this behavior. The assert also
adds an extra benefit to the programmer by documenting that the function
expects and requires the weston_surface to have a shell_surface and
would be a program logic error, otherwise.
The assert() also silences some static analyzers about the possible
NULL deref.

When the last window of the X11 compositor is closed during a fade or
while locked, we'll try to start a fade back to the lock screen. However,
if we closed the last window, there are no outputs left and the animation
will try to run with surface->output == NULL.

This is part of the fix for bug 72540. We cancel the popup grab when the
screensaver kicks in so that the screen unlock dialog can get input events.
The bigger problem is in mesa however, where we try to allocate new buffers
as cairo-gles2 does a gratuituous (but valid) eglMakeCurrent() as we
remove the tooltip or popup-menu.
Since we removed the weston_layer with the regular surfaces, EGL blocks
waiting for a frame event that never comes.

The grab stays alive as long as at least one touch point is down. If touch
point 0 is lifted while other touch points are down, the surface will jump
around when touch point 0 is put down again.
This change marks the grab as inactive once touch point 0 is lifted
and then ignores touch events until all touch points eventually are
lifted and the grab terminates.

Add a config file option to enable it, but leave it off by default. Exposay
still triggers too many lock-ups or stuck grabs and triggers under X even
when the Wayland window doesn't have keyboard focus.
