tests: add data files for future wayland-scanner test

This patch adds the input and reference output data files for the
wayland-scanner tests to be added by the following patch.

The data files are split into their own patch because they are extremely
uninteresting to review:
- example.xml is just a copy wayland.xml from 1.12.0
- small.xml is a tiny dummy definition used for testing scanner
  variations without causing lots of big output files
- the other files are wayland-scanner products from the xml files

+
+      When a client creates a registry object, the registry object
+      will emit a global event for each global currently in the

+      keep the client up to date with the changes.  To mark the end

+      wl_display.sync request immediately after calling
+      wl_display.get_registry.
+
+      A client can bind to a global object by using the bind

+    <description summary="an onscreen surface">
+      A surface is a rectangular area that is displayed on the screen.
+      It has a location, size and pixel contents.
+
+      The size of a surface (and relative positions on it) is described
+      in surface-local coordinates, which may differ from the buffer
+      coordinates of the pixel content, in case a buffer_transform
+      or a buffer_scale is used.
+
+      A surface without a "role" is fairly useless: a compositor does
+      not know where, when or how to present it. The role is the
+      purpose of a wl_surface. Examples of roles are a cursor for a
+      pointer (as set by wl_pointer.set_cursor), a drag icon
+      (wl_data_device.start_drag), a sub-surface
+      (wl_subcompositor.get_subsurface), and a window as defined by a
+      shell protocol (e.g. wl_shell.get_shell_surface).
+
+      A surface can have only one role at a time. Initially a
+      wl_surface does not have a role. Once a wl_surface is given a
+      role, it is set permanently for the whole lifetime of the
+      wl_surface object. Giving the current role again is allowed,
+      unless explicitly forbidden by the relevant interface
+      specification.
+
+      Surface roles are given by requests in other interfaces such as
+      wl_pointer.set_cursor. The request should explicitly mention
+      that this request gives a role to a wl_surface. Often, this
+      request also creates a new protocol object that represents the
+      role and adds additional functionality to wl_surface. When a
+      client wants to destroy a wl_surface, they must destroy this 'role
+      object' before the wl_surface.
+
+      Destroying the role object does not remove the role from the
+      wl_surface, but it may stop the wl_surface from "playing the role".
+      For instance, if a wl_subsurface object is destroyed, the wl_surface
+      it was created for will be unmapped and forget its position and
+      z-order. It is allowed to create a wl_subsurface for the same
+      wl_surface again, but it is not allowed to use the wl_surface as
+      a cursor (cursor is a different role than sub-surface, and role
+      switching is not allowed).

+
+	Buffer scale is double-buffered state, see wl_surface.commit.

+
+	wl_surface.set_buffer_scale changes the pending buffer scale.
+	wl_surface.commit copies the pending buffer scale to the current one.

+
+	The purpose of this request is to allow clients to supply higher

+	intended that you pick the same buffer scale as the scale of the
+	output that the surface is displayed on. This means the compositor
+	can avoid scaling when rendering the surface on that output.
+
+	Note that if the scale is larger than 1, then you have to attach

+	This request is used to describe the regions where the pending
+	buffer is different from the current surface contents, and where
+	the surface therefore needs to be repainted. The compositor
+	ignores the parts of the damage that fall outside of the surface.
+
+	Damage is double-buffered state, see wl_surface.commit.
+
+	The damage rectangle is specified in buffer coordinates,
+	where x and y specify the upper left corner of the damage rectangle.
+
+	The initial value for pending damage is empty: no damage.
+	wl_surface.damage_buffer adds pending damage: the new pending
+	damage is the union of old pending damage and the given rectangle.
+
+	wl_surface.commit assigns pending damage as the current damage,
+	and clears pending damage. The server will clear the current
+	damage as it repaints the surface.
+
+	This request differs from wl_surface.damage in only one way - it
+	takes damage in buffer coordinates instead of surface-local
+	coordinates. While this generally is more intuitive than surface
+	coordinates, it is especially desirable when using wp_viewport
+	or when a drawing library (like EGL) is unaware of buffer scale
+	and buffer transform.
+
+	Note: Because buffer transformation changes and damage requests may
+	be interleaved in the protocol stream, it is impossible to determine
+	the actual mapping between surface and buffer damage until
+	wl_surface.commit time. Therefore, compositors wishing to take both
+	kinds of damage into account will have to accumulate damage from the
+	two requests separately and only transform from one to the other
+	after receiving the wl_surface.commit.

+      A wl_surface, that has sub-surfaces associated, is called the

+      a tree of sub-surfaces.
+
+      The root surface in a tree of sub-surfaces is the main
+      surface. The main surface cannot be a sub-surface, because
+      sub-surfaces must always have a parent.
+
+      A main surface with its sub-surfaces forms a (compound) window.
+      For window management purposes, this set of wl_surface objects is
+      to be considered as a single window, and it should also behave as
+      such.
+
+      The aim of sub-surfaces is to offload some of the compositing work
+      within a window from clients to the compositor. A prime example is
+      a video player with decorations and video in separate wl_surface

+    <description summary="sub-surface interface to a wl_surface">
+      An additional interface to a wl_surface object, which has been
+      made a sub-surface. A sub-surface has one parent surface. A
+      sub-surface's size and position are not limited to that of the parent.
+      Particularly, a sub-surface is not automatically clipped to its
+      parent's area.
+
+      A sub-surface becomes mapped, when a non-NULL wl_buffer is applied
+      and the parent surface is mapped. The order of which one happens
+      first is irrelevant. A sub-surface is hidden if the parent becomes
+      hidden, or if a NULL wl_buffer is applied. These rules apply
+      recursively through the tree of surfaces.
+
+      The behaviour of a wl_surface.commit request on a sub-surface
+      depends on the sub-surface's mode. The possible modes are
+      synchronized and desynchronized, see methods
+      wl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized
+      mode caches the wl_surface state to be applied when the parent's
+      state gets applied, and desynchronized mode applies the pending
+      wl_surface state directly. A sub-surface is initially in the
+      synchronized mode.
+
+      Sub-surfaces have also other kind of state, which is managed by
+      wl_subsurface requests, as opposed to wl_surface requests. This
+      state includes the sub-surface position relative to the parent
+      surface (wl_subsurface.set_position), and the stacking order of
+      the parent and its sub-surfaces (wl_subsurface.place_above and
+      .place_below). This state is applied when the parent surface's
+      wl_surface state is applied, regardless of the sub-surface's mode.
+      As the exception, set_sync and set_desync are effective immediately.
+
+      The main surface can be thought to be always in desynchronized mode,
+      since it does not have a parent in the sub-surfaces sense.
+
+      Even if a sub-surface is in desynchronized mode, it will behave as
+      in synchronized mode, if its parent surface behaves as in
+      synchronized mode. This rule is applied recursively throughout the
+      tree of surfaces. This means, that one can set a sub-surface into
+      synchronized mode, and then assume that all its child and grand-child
+      sub-surfaces are synchronized, too, without explicitly setting them.
+
+      If the wl_surface associated with the wl_subsurface is destroyed, the
+      wl_subsurface object becomes inert. Note, that destroying either object
+      takes effect immediately. If you need to synchronize the removal
+      of a sub-surface to the parent surface update, unmap the sub-surface
+      first by attaching a NULL wl_buffer, update parent, and then destroy
+      the sub-surface.
+
+      If the parent wl_surface object is destroyed, the sub-surface is
+      unmapped.
