The Cairo documentation tells us to always call cairo_device_flush()
before using other rendering APIs on the cairo surface, especially where
the Cairo device shares state with us (that is, EGL and GL state in this
case).
Add a call to cairo_device_flush() into display_acquire_window_surface(),
which the toytoolkit offers for switching to native (GL) rendering.

Create instances from outputs, and register the surfaces as
screensavers. Support multiple "Mode" instances.

Add output_configure_handler as a display property. This exposes only
configured outputs, that is the current mode info is already received,
to applications.
The handler is also called for mode changes on an existing output. This
simplifies the implementation in toytoolkit as we can defer the handler
calls from wl_output binding time to when we receive the current mode.
We do not need separate handlers for "new output" and "mode changed". A
plain "new output" handler would be problematic as the current mode is
not known yet.
Also add delete_handler hook for outputs, but that will never be called
for now, as the protocol lacks a way to signal output disconnections.

Add the screensaver interface to the desktop-shell protocol file. Also
add stubs for it in the compositor, and make wscreensaver to bind to the
screensaver interface. Wscreensaver gets a new option --demo to retain
the current behaviour as a regular wayland client.
When a screensaver application starts, it should bind to the screensaver
interface, enumerate all outputs, create a surface per output, and
register those surfaces via screensaver::set_surface request. Then it
continues with the usual animation loop, waiting for frame events. The
compositor will decide, when the given screensaver surfaces are
displayed. A screensaver application should respond to outputs coming
and going away by creating and destroying surfaces.
The compositor is supposed to activate a screensaver by exec'ing it, and
stop the screensaver by killing the client process. Only one client may
be bound to the screensaver interface at a time. If there already is a
client, the compositor could either kill it first, or not exec a new
one.

Eventually we will want more functionality in the shared library and we
will rename it at that point. Perhaps we'll name it libnih, but for now
let's stick with libconfig-parser.
Add an option to the desktop-shell ini file that defines whether screen
locking is used or not.
Useful for testing screensaver interactions without a lock surface.

As of commit "client: unset WAYLAND_SOCKET env variable",
58bb064afa3bfc706e3b30dd170804235aa272ea, in the Wayland core, the
Wayland library will unset the environment variable automatically.
No need to explicitly unset it again here.

Since it is the desktop-shell plugin in the compositor that offers both
wl_shell global interface and wl_shell_surface interface, those are not
available on the tablet-shell plugin.
The tablet-shell client uses the toytoolkit, so toytoolkit must work
somehow even without wl_shell.
Turn all operations in toytoolkit that would require wl_shell or
wl_shell_surface into no-ops.

Protocol changes in Wayland core introduced a new interface
wl_shell_surface, and moved all wl_shell surface methods into it. Adapt
the compositor and its Wayland backend, shell plugin, and all clients to
the new interface.

When a window destroyed, if any input had the window in keyboard
focus, the keyboard focus is reset to NULL. A new keyboard focus is set
only, if the user clicks something. If the user presses a key instead of
clicking, the key press event is sent to the client which has NULL
keyboard focus, triggering a segfault in window_handle_key().
Fix the segfault by ignoring the key event, if there is no target
window.
I triggered this segfault by clicking the unlock dialog away, and then
pressing a key.

This way we can still use surface->link when a surface is not in
the main compositor surface list and don't need the hidden_surface
wrapper object. Also, setting surface->output to NULL will block
the surface frame callback until we put the surface back into the
main list. This has the effect of blocking animations while a surface
isn't visible.
The unclock dialog is just a normal window with a green ball in it. When
you click the ball, the screen will be unlocked.
Made for testing the screen locking.

Currently, the way to destroy a window in a response to an event (e.g.
button click), is to put a task into the deferred list with
display_defer(). The task will then call window_destroy() from outside
event handling code.
As events are handled, it is possible that the deferred list contains
also the redraw task for this window. As the execution order of these
tasks is unknown (redrawing a freed window is a bug) and redrawing
something that goes away immediately is not useful, the redraw task must
be removed on window_destroy().
'struct input' contains pointers to windows currently in focus for that
input device. These pointers must also be cleared on window_destroy().
This fixes a use-after-free bug for the unlock dialog in desktop-shell
(future commit).
As an irrelevant minor cleanup, window::grab_device member is not used
anywhere, and is removed.

Add protocol and functions for supporting screen locking, triggered by
activity timeout.
After activity timeout, compositor starts the fade to black, and then
enters SLEEPING state. At that point it calls lock() in the shell
plugin.
When input events trigger a wakeup, unlock() in the shell plugin is
called. This sends prepare_lock_surface event to the desktop-shell
client. The screen stays locked while the compositor starts fade-in.
At this point, desktop-shell client usually creates a surface for the
unlocking GUI (e.g. a password prompt), and sends it with the
set_lock_surface request. The compositor supposedly shows and allows
interaction only with the given lock surface (not yet implemented).
When desktop-shell has authenticated the user, or instead of issuing
set_lock_surface, it sends the unlock request. Upon receiving the unlock
request, the shell plugin unlocks the screen.
If desktop-shell client dies, the screen is unlocked automatically.

Add a helper function, that constructs a path to a config file from
XDG_CONFIG_HOME environment variable, by the rules of
http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

Fork and exec desktop-shell in the compositor. This is a way to create
an authenticated client. Later, the desktop-shell interface will be
reserved for this client only.
For exec to work, the compositor should be started from the
wayland-demos' root directory.
