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.

Fix two bugs:
- if there are no backgrounds at all, the background pointer would have
been bogus. Lead to a segfault.
- if the hidden_surface_list is empty, wl_list_insert_list() would
corrupt the list. Lead to a hang in pick_surface().

Enumerate the different surface purposes for the shell: background, panel,
lock surface, and normal (other) surfaces.
Instead of testing wlsc_surface pointers against known pointers, check
the purpose field.
This change will ease implementing per-output background, panel, etc.
when the number of "known" surface pointers grows dynamically.

Add a pointer to wlsc_surface for shell-private data. This is a
temporary solution.
Add struct shell_surface, where you can add any shell-private data
members related to a wlsc_surface. The getter function takes care of
creating the private data if it does not exist yet.
Not used anywhere yet.

Since I have commented out all the config structures in glmatrix.c, it
was not getting proper default values. Hardcode some default there.
Remove glClear from reshape_matrix(), as wscreensaver does not support
rendering commands in reshape call.

Very likely that 2.4 kernels won't be used with Wayland compositor so the
check for signal value is pretty much useless.
It's okay to change e->value inside evdev_process_absolute_motion_touchpad
given it's not used later on, and I also rather not touch this snip because it
will be changed when multi-touch support arrives.

A copy & paste bug, that resulted setting to NULL something else than
shell->lock_surface when that surface was destroyed.
The symptom: let compositor lock down, unlock it, let it lock down
again, and the unlock dialog is never requested again. This bug was
triggered by the previous fix "shell: fix compositor wakeup while
locked".

Compositor is locked, woken up, unlock dialog is shown; if the
compositor does to sleep again, before being unlocked, it will never
wake up again, because unlock() becomes a no-op, yet it should wake the
compositor up.
Fix this by letting unlock() to wake up the compositor, if lock surface
is present.

When the lock surface was map()'d while the compositor was locked,
wlsc_surface_configure() was never called for the lock surface. Hence,
the surface->output was NULL, and the 'frame' event was never sent,
causing desktop-shell to loop in dri2_swap_buffers().
Fix this by calling wlsc_surface_configure() for the lock surface
always in map().
Additionally, adjust the comments in map() to make it more readable.

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.

When the compositor is locked, all surfaces are moved from the
compositor's list to a private list in the shell plugin. This prevents
any of those surfaces from being visible or receiving input. All new
surfaces will be moved to the private list, too.
The background surface is an exception, it is left to the compositor's
list, so the background will be painted. It is assumed that the
background surface does not allow any actions while being locked.
When desktop-shell announces a lock surface (an unlock dialog), it is
added to the compositor's list, so the user can interact with it.

Check that wlsc_surface::link is part of a list before assuming it is
part of the compositor->surface_list list.
The shell plugin may want to remove a surface from the compositor's
surface list to hide it. Note, that the shell plugin cannot use
wlsc_surface::link for its own purposes.

wlsc_compositor_fade() ends up in wlsc_compositor_schedule_repaint(),
which is a no-op if compositor is SLEEPING.
On wakeup, first set status to ACTIVE, then call wlsc_compositor_fade()
to start and actually show the animation.
Before, fade was called first, which reset the animation, but did not
cause a repaint. The following wakeup (any input event) would then cause
a repaint, showing the animation from the middle or end of it.

With the idle_inhibit optimization, wlsc_compositor_wake() is a no-op if
idle_inhibit > 0.
When the shell is waking up the compositor from SLEEPING state as an
indirect response to input activity, it does not work. The call path is:
notify_key() / notify_button()
wlsc_compositor_idle_inhibit()
wlsc_compositor_activity()
shell->unlock()
send prepare_lock_surface event
idle_inhibit++
and when the desktop-shell client responds to the event:
desktop_shell_set_lock_surface() / desktop_shell_unlock()
wlsc_compositor_wake()
no-op, because idle_inhibit > 0
Fix this by removing the idle_inhibit check from wlsc_compositor_wake().
The optimization did not work for pointer motion while no keys pressed,
anyway, so the performance hit is probably unobservable.
Now the compositor wakes up also on key or button press.
