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.
v2: rename surface_base to wsurface

Add an assert to ensure that a window of type XWAYLAND is never
attempted with a parent. Following the code though, the assert can be
made even stricter by allowing only TRANSIENT to have a parent.
This is essentially adding documentation.

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.
