when output is removed, weston-desktop-shell should destroy panel
and background surface on destroyed output.

And check if the renderer supports the RGB565 format for wl_shm buffers
before creating the cairo surface and requesting the buffer.
It can save quite some memory with big surfaces such as desktop
backgrounds.
The panel and background were never created for hotplugged outputs and
since some parts of the code assume that they always exist that would
lead to desktop-shell client to crash in that case.
This was easier to spot when the display was locked, because Weston
respawns the shell client and the user might not notice since there is
no flicker.

This lets the code for adding panel launchers and setting up the
background to be moved into panel_* and background_* functions.
Note that this changes the behavior of the default launcher. Before
this change a default launcher would be added only if there was no
config file. Now a launcher is also added if there is no valid
launcher section.
Scale-crop mode scales the wallpaper to tightly fill the whole output,
but preserving wallpaper aspect ratio. If aspect ratio differs from the
output's, the wallpaper is centered cutting it from top/bottom or
left/right.
Add this to the weston.ini man page, and explain all three modes.

On Raspberry Pi, weston-desktop-shell is so slow to start, that the
compositor has time to run the fade-in before the wallpaper is up. The
user launching Weston sees the screen flipping to black, the fbcon
fading in, and then the desktop popping up.
To fix this, wait for the weston-desktop-shell to draw
everything before starting the initial fade-in. A new request is
added to the private desktop-shell protocol to signal it. If a
desktop-shell client does not support the new request, the fade-in
happens already at bind time.
If weston-desktop-shell crashes, or does not send the 'desktop_ready'
request in 15 seconds, the compositor will fade in anyway. This should
avoid a blocked screen in case weston-desktop-shell malfunction.
shell_fade_startup() does not directly start the fade-in but schedules
an idle callback, so that the compositor can process all pending events
before starting the fade clock. Otherwise (on RPi) we risk skipping part
of the animation. Yes, it is a hack, that should have been done in
window.c and weston-desktop-shell instead.

We pick the window scale/tranform based on what the output uses, which means
we can avoid rotations in the compositor, and get sharper rendering
in scaled outputs.
This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config. This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.
To avoid a TOCTOU race the config file is actually open()ed during the
search. Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.

Toytoolkit does not support setting opaqueness for anything else than
the immediate child widget of the frame widget. Backgrounds do not have
frames, so we need to poke it in manually.
This should allow Weston to paint the background without blending.

desktop-shell never returned from display_run() since it
was essentially killed when weston exited. To fix this,
it is necessary to watch for EPOLLHUP in window.c so that
toytoolkit clients will return from display_run() when
weston quits. This allows for clients to clean up
as needed.

The variable '__environ' seems to be libc implementation specific, and

We now support specifying environment variables and arguments in launchers
by saying

window.c:1173:6: warning: ignoring return value of ‘read’, declared with attribute warn_unused_result [-Wunused-result]

We don't gain anything from taking a wl_shell_surface in
desktop_surface.set_background, except making wl_shell_surface
gratuitously dependent on wl_shell. In shell.c we can also handle
backgrounds in their own background_configure function which simplifies
the mapping and placement logic.
Since the introduction of pointer.set_cursor(), it is possible for a
client to set the surface containing the pointer image and get frame
callbacks on it thus allowing a clear implementation of animated
cursors.
This also makes the busy cursor hack of using frame callbacks on the
busy surface unnecessary.
Putting panel_add_clock in launcher_section_done handler
will cause clock to be created multiple times with every launcher.
Fix is to move the call to panel_create function.
In clock_func() it is necessary to read the timer fd, or
it will stay readable, and the event loop will call the function again.
That causes an endless loop.
Instead of using a uint32_t for state everywhere (except on the wire,
where that's still the call signature), use the new
wl_pointer_button_state enum, and explicit comparisons.

On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
If you don't have anything at ~/.config/weston-desktop-shell.ini and
have weston installed somewhere other than /usr, then this patch will
help.

When a menu self-destructs, free also the widget and struct menu.
As menus are self-destructing, it does not make sense to store the
window pointer, since we cannot clear it automatically. Therefore,
rename window_create_menu() to window_show_menu() that does not return
the window pointer. It also calls window_schedule_redraw() internally.
Fixes Valgrind reported memory leaks.
The alternative would be to explicitly destroy the menu in application's
menu callback.

The decorations were not responding, could not move or resize the
dialog, and it painted with a black shade.
When the dialog is created, schedule a resize instead of a repaint. The
resize will initialise the widget tree, and let everything draw and work
as it should.

This lands the basic behavior of the popup surface type, but there are still
a number of details to be worked out. Mainly there's a hardcoded timeout
to handle the case of releasing the popup button outside any of the
client windows, which triggers popup_end if it happens after the timeout.
Maybe we just need to add that as an argument, or we could add a new event
that fires in this case to let the client decide whether it ends the popup
or not.
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.

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.

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.
