924e79f4f2 ivi-shell: emit created notification earlier for desktop surfaces
Without this, the earliest signal the ivi controller receives for a new surface
is configure_desktop_changed signal. And this is not emitted until the surface
has the first buffer attached.
By emitting the signal during surface creation, the controller is able to set
the initial width and height for the first configure.

6ffbba3ac1 Use weston_compositor_add_destroy_listener_once() in plugins
This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.

Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.

All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
  did not fit there.

Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.

Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

eaa43fc310 ivi-shell: add API for weston_surface -> ivi_layout_surface
Add ivi-layout API for getting an ivi_layout_surface from a
weston_surface if it exists. This can be used by controllers that hook
up to core Weston callbacks and get handed a weston_surface, but need to
use ivi-layout API to manipulate it.

The only ways ivi-layout itself would be able to go from weston_surface
to ivi_layout_surface are either searching through the list of all
ivi_layout_surfaces or adding a dummy destroy listener to the
weston_surface. Therefore the implementation is delegated to
ivi-shell.c.

Ivi-shell.c can easily look up the ivi_shell_surface for a
weston_surface, and that will map 1:1 to an ivi_layout_surface.

1f82193379 ivi-shell: call shell_surface_send_configure() directly
For some reason, it seems that ivi-layout.c has tried hard to avoid
calling directly into ivi-shell.c. This means there is a jump through
hoops just to get the configure event sent to the clients. Ivi-shell
registers a listener for a ivi-layout signal for sending the event.

Instead, let ivi-layout.c call directly into ivi-shell.c, and expose a
function to send out the configure events. This reduces some confusion
on who calls what.

The main idea though is that this makes ivi-shell.c not depend on struct
ivi_layout_surface fields directly anymore. In following patches,
ivi_layout_surface can be made opaque for ivi-shell.c.

0627b4a73d ivi-shell: activate weston surface with a seat when left click or touch.
Similar with Desktop shell, set activate to weston surface which is
left-clicked by pointer or touched. This is needed to focus it with a seat.
Without this, a feature who gets activated weston surface by using
weston_surface_get_main_surface doesn't work correctly because it can
not get correct focused weston surface. For example, input-panel uses
weston_surface_get_main_surface to get a weston surface. With this
weston surface, it get a member: output to decide which output shall
show a input-panel, software keyboard. Without activation,
input-panel-ivi can not find a correct output which shows e.g.
weston-editor who uses input-method.

8ae2db5b0c input: Pass the appropriate pointer type to bindings instead of a seat
Normally we need to check if a seat's [device_type]_count is > 0 before
we can use the associated pointer.  However, in a binding you're
guaranteed that the seat has a device of that type.  If we pass in
that type instead of the seat, it's obvious we don't have to test it.

The bindings can still get the seat pointer via whatever->seat if they
need it.

This is preparation for a follow up patch that prevents direct access
to seat->device_type pointers, and this will save us a few tests at
that point.

aa9536a992 text_backend: make destructor call explicit
We used to rely on the order in which the
weston_compositor::destroy_signal callbacks happened, to not access
freed memory. Don't know when, but this broke at least with ivi-shell,
which caused crashes in random places on compositor shutdown.

Valgrind found the following:

Looking at the first of these, unbind_input_panel() gets called when the
text-backend destroys its helper client which has bound to input_panel
interface. This happens after the shell's destroy_signal callback has
been called, so the shell has already been freed.

The other two errors come from
  wl_list_remove(&input_panel_surface->link);
which has gone stale when the shell was destroyed
(shell->input_panel.surfaces list).

Rather than creating even more destroy listeners and hooking them up in
spaghetti, modify text-backend to not hook up to the compositor destroy
signal. Instead, make it the text_backend_init() callers' responsibility
to also call text_backend_destroy() appropriately, before the shell goes
away.

This fixed all the above Valgrind errors, and avoid a crash with
ivi-shell when exiting Weston.

Also using desktop-shell exhibited similar Valgrind errors which are
fixed by this patch, but those didn't happen to cause any crashes AFAIK.
