Implement shm_surface as a sub-class of toysurface, and unify the
toysurface call sites removing most buffer type specific branching.
Do not destroy and create a surface, if the size does not change.
The resizing optimization of shm surfaces is retained, but the pool is
moved from struct window to struct shm_surface, since it does not apply
to egl_window_surface.

We need more structure to the way we handle the backing storage in
toytoolkit, to make it possible to double-buffer the shm case properly.
The existing buffer handling is very complex with the three
different cases:
- EGLSurface backed Cairo surface with a window associated
- wl_shm backed Cairo surface with a window associated
- wl_shm backed Cairo surface without a window, as used by dnd.c
Introduce the toysurface abstraction, which defines the interface for
the both buffer handling cases that have a window associated. It also
means, that windows will not have a valid Cairo surface outside of their
repaint cycle.
Convert the EGLsurface case into toysurface for starters. For EGL-based
Cairo surfaces, the private data is no longer needed. Destroying
egl_window_surface will trigger the destruction of the cairo_surface_t,
not vice versa. This is possible because display_create_surface() is
shm-only.
The shm cases are left untouched.
As a side-effect, display_acquire_window_surface() and
display_release_window_surface() will no longer use the 'display'
argument. Instead, display will be the one inherited from the window.

Toytoolkit doesn't buy us anything in this case, we're not rendering or
handling regular input events. Just talk directly to wl_display and
look up the 'input_method' global directly.
The key events we pass through to the input_method_context has to have
a serial number that corresponds to the key event we got. The struct display
serial is updated on pointer enter/leave and keyboard events, but not the
input method keyboard events. So the display serial will never correspond
to the key event we're dealing with and we have to pass through the
serial we get from the key event.
This simple change allows you to drive the editor using the keyboard
(supporting backspace and delete and left and right arrow keys.) The idea
behind this change is to allow the testing of the interoperation between a
virtual keyboard and real one.

Rename the key event in text_model to keysym and add serial, time and
modifiers arguments. Add a modifiers_map event to transfer an array of
0-terminated modifier names, so that a mapping of modifiers to the
modifier bit mask is possible.

This new client, called transformed, renders a cross with the top part
red and the right green, with the same transform as the output the
surface is in.
This is based on simple-egl.
Implement the wl_surface.set_buffer_transform request. This includes
tracking the double-buffered buffer transformation parameter and making
the gl renderer able to handle transformed buffers.

Backends may move surfaces to different planes, in which case damage is
generated in the primary plane. This damage is usually passed to the
renderer, but in some cases the backend may decide to not render
anything (that's the case when drm compositor scans out a client
buffer). In that case the damage on the primary plane would be
discarded, leading to artifacts later.
This patch makes the backend's responsibility to clear the damage on
the primary plane, so that unrendered damage is kept for as long as
necessary.
On the first frame with zoom activated, the spring used for animation
will have a current value of zero. The translation calculated with that
value will be invalid (not a number). Using this value later leads to
having an invalid output matrix, so nothing is composited in the first
zoomed frame.
This problem is most evident when a sprite plane is being used. In that
case, enabling the zoom will cause the surface to be moved back to the
primary plane, but because of the bug described above, this surface
would not actually be rendered causing a quick flicker.
If simple-egl is toggled fullscreen, the opqaue region is set for the surface
but never removed after exiting fullscreen. This patch resets the opaque region
to 0 if the surface is not fullscreen and -o was not passed. This fixes the
problem introduced sometime since d7f282b84e, when this was last fixed.
Nothing uses it to create EGL-surfaces outside of window.c. This makes
refactoring the EGL-based code easier, since we do not need to support
EGL-based Cairo surfaces without an associated struct window.

cairo_surface_t objects have a private set, either struct
shm_surface_data, or struct egl_window_surface_data. Use separate
private keys for each type to avoid mismatch.
This makes display_get_buffer_for_surface() safe, in that it won't
return garbage for an EGL-based cairo surface.

Struct surface_data was not really useful, and it definitely was not
used with EGL-based windows.
This also fixes a semantic mistake, where struct shm_surface_data was
put into cairo_surface_t private, but got out as struct surface_data
instead. Due to struct layout, however, this did not cause a real bug.

Change simple-shm to properly process the wl_buffer.release event, and
not reuse a buffer until it is released by the server, as specified in
the protocol.
In case the server has not released the buffer, but signals that it has
been shown (frame callback), allocate a second buffer. Simple-shm will
now automatically do double-buffering if needed.

Move fields current_buffer and buffer_damage out of weston_output into
gl_output_state, since they are actually specific to the renderer.
Also bring back the previous_damage field so that the screenshooter
can get the damage for the previous frame in a renderer independent
way.
disable_planes should only be incremented when zoom.active actually
toggles. Otherwise the counter will be incremented too many times,
and planes will no longer get used.
