The xwm used to automatically send to Xwayland the position of X windows
when that changed, using the x,y of the primary view of the surface.
This works fine for the desktop shell but less so for others.
This patch adds a 'send_position' vfunc to the weston_shell_client that
the shell will call when it wants to let Xwayland know what the position
of a window is.
The logic used by the desktop-shell for that is exactly the same the xwm
used to have.

The xwm gets a primary view for a X window using the get_primary_view
vfunc of the shell_interface struct. Storing it is dangerous though
because it doesn't listen for its destruction so it may end up using the
old stored view pointer after that view was freed, or after the primary
view for that window was changed to another one.
Fetch the primary view just before using it every time and try to not
abuse this 'primary view' concept which may map badly to some shells:
iterate over all the views instead when it makes sense.

If windows are created and quickly destroyed it's possible that they'll be

destroy listener for that surface isn't properly freed and a crash happens
some time later.
This patch removes the window from the unpaired list during unmap, so we
should never get to the destroy handler with a surface destroy listener set.
Just in case there's another path to that failure, I've also removed the

The xwm currently has no way to know how many virtual desktops
the shell plugin has, or if it even implements the metaphor. For now
just set the property to 0, meaning the first desktop, if the window is
mapped, and delete the property when unmapped.

With the more accurate definition of wl_surface roles in Wayland,
enforce the restriction: a role is always set permanently, and
attempting to change it is a protocol error.
This patch is based on Jasper's patch:
http://lists.freedesktop.org/archives/wayland-devel/2014-August/016811.html
The difference in this patch compared to his are:
- send role errors on the interface whose request triggers it, not on
wl_surface
- an interface could have several requests assigning different roles,
cannot use wl_interface as the unique key; use an arbitary string
instead
- ensure in window-manager.c that create_shell_surface() ->
create_common_surface() is never called with surface->configure set,
to avoid compositor abort
- use wl_resource_post_no_memory() where appropriate instead of
hand-rolling it with wl_resource_post_error()
Ideally we would not add weston_surface::role_name field, but use
weston_surface::configure. At the moment this is not possible though,
because at least shell.c uses several different roles with the same
configure function. Drag'n'drop uses two configure functions for the
same role. The configure hook is also reset in several places,
which is not good for role tracking.
This patch overlooks the wl_surface roles assigned in privileged
extensions: screensaver, panel, background, lock, input panel.

XCB and wayland input event handling exists together in xwm, which can
cause problems. weston_wm_handle_button is called via XCB events, while
it calls weston_wm_pick_seat_for_window, which uses info from compositor
(pure wayland). It is also true in setting and removing flags of frames.
Races can happen in between, when resize of moving flag of the frame is
still set while the button has been released, the picked seat will be
NULL in weston_wm_handle_button, causing crash. We can safely ignore
moving or resizing if this happens. The same applies to c06a180d.

If X windows are created and destroyed very fast sometimes the WM window
object gets created and destroyed before we get around to handling client
messages. Failing to check that the window is still valid can result in a
segfault.
When Xwayland requests that a wl_surface be created and the X event is
handled before the wayland requests, a surface ID is stored to
window->surface_id and the window is added to the unpaired window list. When
weston_wm_create_surface is called, the window is removed from the list and
window->surface_id is set to zero. If window->surface_id is not zero when
weston_wm_window_destroy is called, the window is assumed to be in the
unpaired window list and wl_list_remove is called. If
weston_wm_window_handle_surface_id is called and the surface has already
been created, the window is not added to the unpaired window list, but
window->surface_id isn't set to zero. When the window is destroyed, removing
the window from the list is attempted anyway and a crash occurs.
This patch stores the surface ID in a temporary variable and only assigns it
to window->surface_id when the window is added to the unpaired window list.
Otherwise window->surface_id is set to zero to maintain its use as a flag
variable.

Currently, there is a fun flicker when toggling maximization or
fullscreen on a window in mutter or more sophisicated compositors
and WMs.
What happens is that the client want so go maximized, so we
calculate the size that we want the window to resize to (640x480),
and then add on its margins to find the buffer size (+10 = 660x500),
and then send out a configure event for that size. The client
renders to that size, realizes that it's maximized, and then
says "oh hey, my margins are actually 0 now!", and so the compositor
has to send out another configure event.
In order to fix this, make the the configure request correspond to
the window geometry we'd like the window to be at. At the same time,
replace set_margin with set_window_geometry, where we specify a rect
rather than a border around the window.
send_configure was originally modelled after
wl_shell_surface::send_configure, which takes these arguments. However,
the X WM and xdg_surface::configure variants don't use these arguments.
We already store the resize edges for a surface while it's being
resized, so just use the saved state in the wl_shell_surface variant.
