27839fe913 ivi-shell: remove unused functions and members
input panel related members of ivi_shell struct are
not required anymore. Also get_default_view(),
input_panel_setup() and input_panel_destroy() are not used.
Therefore, we can remove them.

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.

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.

28dc18c843 ivi-shell: make ivi-layout.c as a part of ivi-shell.so
ivi-layout.so is separately built and loaded by using dlopen with
RTLD_GLOBAL. This was because these apis defined in ivi-layout.so shall
be used by ivi-modules; e.g. hmi-controller. This shall be improved that
a struct ivi_layout_api contains the whole exported API as function
pointers to be exposed as module_init.

This patch alone builds, but loading controller modules at runtime
failes. This failure will be fixed by following patches.

487adc4699 ivi-shell: add the shell plugin for In-Vehicle Infotainment system
- ivi-shell.so
- introduces ivi-shell/ivi-shell.[ch]

In-Vehicle Infotainment system traditionally manages surfaces with
global identification. A protocol, ivi_application, supports such a
feature by implementing a request, ivi_application::surface_creation
defined in ivi_application.xml.

The ivi-shell explicitly loads ivi-layout.so and a module to add
business logic like how to layout surfaces by using ivi-layout APIs.
