Drop support for the obsolete xdg-shell v5 protocol. This clears the
path to properly support xdg-shell stable, since xdg-shell stable and
xdg-shell v5 can't currently co-exist in the same compositor, as both
define structures with the same name (such as struct
xdg_surface_interface).

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.

Instead we store the buffer move and just use it when the signal is
fired.

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.
