One less syscall and error path to check, and feels like a cleaner approach.
The commit adds two lines, but that's because we actually handle the
potential error now.
The signal mask is inherited over fork() and exec(), we need to
explicitly reset it.
This allows the children to receive the signals the compositor itself
has blocked, for example SIGINT and SIGTERM.

shell.c and tablet-shell.c had almost the same code for forking their
special shell client. Generalise this code and put it into
wlsc_client_launch() in compositor.c.
Improve error cleanup and reporting in wlsc_client_launch().

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.

Rename CONFIG_KEY_BOOL to CONFIG_KEY_BOOLEAN, just like
CONFIG_KEY_INTEGER is not CONFIG_KEY_INT, for consistency.
Document the types expected for the void* and name the enum in the
header, so it is clear what config_key::type means.

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.

(!x < 0) is always false and doesn't make sense here. Looks like a typo so
remove the negation.

Do not allow multiple wl_shell_surface objects to be created for a
wl_surface object.
Multiple shell_surface objects would confuse the compositor as they
contain separate instances of the shell-private data.

Leftovers from an intermediate patch set, the proper function name is
shell_get_shell_surface. Cosmetic change.

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.

get_shell_surface() returns NULL, if the client has not created or has
destroyed the wl_shell_surface object.
All but one use of get_shell_surface() just retrieve the surface type,
so just fall back to SHELL_SURFACE_NORMAL there.
Resize hot-key binding really needs the wl_shell_surface object, as that
is the only way to send configure events. For surfaces without a
wl_shell_surface, simply do not resize them.

Remove shell_priv member from wlsc_surface, and replace it by a search
through the wl_surface destroy_listener_list.
This technique avoids any "extension" members in the wlsc_surface
structure.

Change desktop-shell protocol to use wl_shell_surface instead of
wl_surface.
Adapt the desktop-shell client and the shell plugin.

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.
Depends on the Wayland core commit "protocol: introduce wl_shell_surface"

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.
