Add calls to wl_shm_buffer_begin/end_access

This wraps all accesses to an SHM buffer between wl_shm_buffer_begin
and end so that wayland-shm can install a handler for SIGBUS and catch
attempts to pass the compositor a buffer that is too small.
westoy: Remove window_touch_move

It seems to be the same as window_move, except it ignores the passed
in serial (???) and instead just uses the one of the display.
westoy: Remove unused support for window parents

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.
westoy: Remove some accessors for wl_shell / wl_shell_surface

We want to remove support for these deprecated interfaces. Since
nothing is using them, this is a simple change.
compositor: Schedule a repaint in weston_view_damage_below()

We always want a repaint if the view was damaged or changed.  In
particular, we want weston_view_update_transform() to schedule a
repaint for the old and new position if we change the view transform.
weston-test: Always update transform when moving surface

weston_view_update_transform() will post damage in the old and new
positions of the view and thus make sure we always repaint properly.
In particular, in bug 66133, the test suite moves the surface off
any output and weston_surface_schedule_repaint() in commit fails to
do anything, since the surface is not on any output.

After changing view geometry, we have to either call
weston_compositor_schedule_repaint(), which is what shell.c typically
does, though that repaints all outputs, or call
weston_view_update_transform() to force update the transformation
and queue repaints on affected outputs.

input: add a motion signal to weston_pointer

The signal will be emitted after the pointer is moved. A shell plugin
can listen to the signal and activate certain effects when the pointer
touches the screen corners, for instance.
zoom: use the new pointer motion signal to move the zoom frame.
input: let the pointer motion handlers move the pointer

this allows to implement pointer barriers by using a custom handler
compositor: add a way to override the default pointer grab
Add [core] backend option

This allows specifying a particular backend to load in a manner similar to
modules.

protocol: move sub-surfaces to Wayland

This reverts commit 2396aec6842c709a714f3825dbad9fd88478f2e6.

This exact version of the sub-surface protocol has been copied into
Wayland core. Therefore it must be removed from here to avoid build
conflicts and useless duplication.

No other changes to sub-surface protocol consumers are needed, the
identical API is now offered by libwayland-client and libwayland-server.

The commit adding sub-surfaces to Wayland is:

Wayland backend: set the opaque region when starting fullscreen

The opaque region is not set when we start the nested
compositor fullscreen. This patch fixes this.

animation, shell: add kbd focus change animation

When enabled, this will make all but the keyboard-focused window dim.
Also the background gets dimmed, if there are any windows open. The
panel is not dimmed.

When the keyboard focus changes, the change in dimming is animated.

The dimming is implemented with transparent solid-color surfaces, two at
most. The net effect of two overlapping dim surfaces is kept constant
during animations (stable fade animation).

There is a new weston.ini option "focus-animation", that defaults to
none, and can be set to "dim-layer" to enable the focus change
animation.

[pq: Sliced, squashed, and rebased the patch series. Fixed surface alpha
interaction with the switcher. Wrote the commit message.]

Add modifier-only binding

Add the ability to bind to modifiers; the binding is armed when a key
which sets the requested modifier is pressed, and triggered if the key
is released with no other keys having been pressed in the meantime, as
well as mouse buttons or scroll axes.

This only works for direct modifiers (e.g. Shift and Alt), not modifiers
which latch or lock.

[pochu: rebased]
Add move/scale animation

Add an animation which moves a surface to a new location, at the same
time as also rescaling it to a different size from the origin, rather
than the existing scale animation which resizes from the centre.

[pochu: rebased, ported to weston_view]
Add Exposay

Exposay provides window overview functions which, when a key which
produces the binding modifier is pressed on its own, scales all
currently-open windows down to be shown overlaid on the desktop,
providing keyboard and mouse navigation to be able to switch window
focus.

input: Don't send leave events to destroyed views

If a view which has focus is destroyed, we would send a leave
event while changing focus, causing a segfault. Prevent this
by listening to the view's destroy signal and removing it from
the pointer focus.
