Assigning a string constant (i.e. memory that we didn't allocate)
to a char* pointer and then freeing that pointer is bad news.

In frame_create, we need to destroy any frame buttons created
in preceding calls to frame_button_create during the function
execution if any of the successive calls to frame_button_create
fail.
This has minimal severity since most, if not all, cases in
frame_button_create that result in a fail (i.e. NULL result) means
a program is OOM and the program will have to exit/abort anyway.

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.

exposay_highlight_surface() is called from exposay_pick(),
exposay_layout(), and exposay_maybe_move() where the esurface
parameter is already validated prior to the call. This makes
the 'esurface' NULL check redundant. This assumes any future
calls to exposay_highlight_surface() will also validate the
'esurface' parameter prior to the call.
This fixes the logic in exposay_highlight_surface so static
analyzers don't complain about the possibility that 'view'
might be NULL deref'd when a 'esurface' == NULL condition is
true.

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.

The opaque region is in surface coordinates, which we compare to the
output region, which is in compositor coordinates. For non-primary
outputs, that means that the output region is not located at 0,0 but
something like 1920,0 instead. That means that the output region isn't
contained in the surface opaque region and then we decide we can't scan
out from it.
Instead, compare the surface opaque region to the output region
translated to 0,0.

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.
This fixes a regression caused by either 918f2dd4 or da75ee1d. In
particular, if a client called commit without attaching a buffer and if the
compositor had already released its reference to the buffer, then a size of
0x0 would be set on the surface. In particular, this affects the wayland
backend because it frequently sends only a frame request in order to cause
a refresh.

There's a small window between the input method (eg the on-sreen keyboard)
receiving the deactivate and destroying the context, where the keyboard may
send requests, which we forward to the destroyed input method. Fix this
by setting the contexts model to NULL right away and then avoid sending
events if context->model is NULL.

If we destroy a window with an active tooltip, we leave the tooltip
hanging around. Call tooltip destructor when destroying a window.
This fixes the stuck tooltip observed when unplugging a monitor with
an active tooltip on the panel.

We now track the child surfaces of a shell surface and the child surfaces
have a pointer back to their parent. We need to clean all this up and
NULL out the childrens parent pointers when a shell surface is destroyed.

The keyboard is too chatty, make it use a dbg() function for logging
which defaults to disabled.
Also drop a noisy fprintf() in input_panel_configure().
strncat() into a newly allocated buffer isn't well-defined. I don't know
how this didn't crash all the time, getting blocks from malloc() with
a NUL in the first byte must be fairly common.

It's possible to touch a surface to move it and let go before we get
to common_surface_move(), in which case we don't have a touch focus
when we get there. For pointers, we could click a surface, but have the
surface go away before we get to common_surface_move(), in which
case the button count is non-zero, but we don't have a surface.
In either case we crash, so let's add a check to make sure we still
have a focus surface before we try to move it.

The subsurfaces example creates a subsurface widget and uses EGL to
render to it directly rather than using the cairo context from the
widget. In theory this shouldn't cause any problems because the westoy
window code lazily creates the cairo surface when an application
creates a cairo context. However commit fdca95c7 changed the behaviour
to force the lazy creation at the beginning of each surface redraw.
This ends up making the triangle surface get two attaches – one from
Cairo and one from the direct EGL.
It looks like it would be difficult to reinstate the lazy surface
creation behaviour whilst still maintaining the error handling for
surface creation because none of the redraw handlers in the example
clients are designed to cope with that. Instead, this patch adds an
explicit option on a widget to disable creating the Cairo surface and
the subsurface example now uses that.
