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.

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.

It is quite possible for os_create_anonymous_file() to fail when trying
to allocate a new wl_shm buffer. Propagate this failure out from
shm_surface_prepare. Most parts of toytoolkit are already avoiding NULL
cairo surfaces.
If cairo surface allocation fails, do not try to call the widget redraw
functions, those are not prepared to deal with NULL. Also do not
schedule a frame callback, this allows us to retry drawing the next
time.
If redraw fails for the main_surface of a window, restore the widget
geometry to what the compositor currently is showing. This keeps the
window visual appearance in sync with application state, so interacting
with the application does not break too badly.
If the very first draw of any window fails, then forcefully exit the
program. E.g. if weston-desktop-shell fails to allocate buffers for the
unlock dialog, w-d-s exits, and weston unlocks the screen automatically.
This patch allows e.g. weston-terminal to stop from enlarging while
resizing, if new sized buffers can no longer the allocated. Even then,
the application stays usable, as it can often repaint in the last
successful size. It does not crash, and the user is able to resize it
smaller, too.

Data device interface in client just handle with pointer's dnd.
If a touch screen trigger dnd, it will use pointer struct like i
nput->sx, input->sy, input->pointer_focus. So if pointer is moving
when touch screen trigeer a dnd, wrong behaviore will occur.
Before touch screen start dnd, system call touch_grab()
to mark the following drag and drop operation is generated by
touch screen.
Defined some common variables in struct input to track dnd.
Note, touch screen and pointer can't generate drag and drop at the
same time, becuae data device protocol can't identify the drag
and drop event is generated by touch screen or pointer.

It seems that this was only used by the popup menu infrastructure,
which can handle this all on its own. Implementing e.g. transients
in the future can be done with a simple xdg_shell_set_transient_for.
We used to ungrab first to stop any existing grab and then grab after
showing the menu. That was broken in c680e90489, which
moved the ungrab down below the grab, and as a result menus are now
shown without a grab. This commit moves the grab back up.
when output is removed, weston-desktop-shell should destroy panel
and background surface on destroyed output.

The decorations tiles start to overlap and look weird if we go below
200x200 size windows. Just set that as a minimum size if the app
doesn't provide a bigger minimum size.

And check if the renderer supports the RGB565 format for wl_shm buffers
before creating the cairo surface and requesting the buffer.
It can save quite some memory with big surfaces such as desktop
backgrounds.
For the sample clients we introduce xmalloc() to simplify OOM-handling.
This patch only converts a few callsites, but this will be our strategy
going forward.
