The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.

This fixes a race between Xwayland committing the surface content via
the wl_surface, and the XWM setting the role of the surface.
We now keep track of the (first) content commit on the surface and
forward it to the shell when we finally get the role.
There is no need to track later changes, as the only way for Xwayland to
unmap a surface is to destroy it.

When we receive configure_notify we should update the surface's
position by calling xwayland_api->set_xwayland(). Otherwise some surfaces
like dnd surfaces from xwayland views are "stuck" at one place. When
setting XWAYLAND state though we should always call view_set_position(),
not just the first time we set this state.

Fix up the window position whenever the geometry info changes.
If the window geometry changes, we want to keep the input-responding

X11 applications expect -geometry command line option to work for
setting the initial window position, but currently this does not work.
Add provision to relay the initial position through libweston-desktop:
- weston_desktop_api gains a new entry set_xwayland_position
- implement set_toplevel_with_position() in xwayland internal interface
Once xwayland plugin starts calling set_toplevel_with_position(),
libweston-desktop can relay that information to a shell if the shell
wants to hear it.
If a shell does not implement the set_xwayland_position hook, the
old behaviour remains: the shell positions xwayland toplevels like any
other.

Currently, layers’ order depends on the module loading order and it does
not survive runtime modifications (like shell locking/unlocking).
With this patch, modules can safely add their own layer at the expected
position in the stack, with runtime persistence.

The xwayland window type XWAYLAND is not handled by the shell at all,
instead libweston-desktop maps such surfaces itself. However, it forgot
to set weston_surface::is_mapped and weston_view::is_mapped.
weston_surface::is_mapped affects the behaviour of weston_view_unmap()
and weston_surface_attach().
weston_view::is_mapped affects the behaviour of weston_view_unmap() and
weston_view_destroy().
When manually mapping a window of type XWAYLAND, mark both the view and
surface as mapped. This follows the expections in libweston, even though
the meaning of is_mapped is not clearly defined for either surface or
view.
Also, when the XWAYLAND window is manually unmapped, unmap the
weston_surface. This updates weston_surface::is_mapped to reflect the
state. However, as a side-effect it will also unmap all sibling views,
should any exist.

libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.
The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.
The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.
The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.
All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).
All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.
