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.

ee8e5830be ivi-shell: rewrite controller API
This fixes the breakage caused by "ivi-shell: make ivi-layout.c as a
part of ivi-shell.so"

hmi-controller.c:
A reference implementation of controller module does not use the layout
functions directly. This get function pointers at controller_module_init
which called by ivi-shell.

ivi-layout-export.h:
Definition of interfaces in a struction: ivi_controller_interface.
function pointers are set at ivi-layout.c.

ivi-layout-private.h:
Definition of some interfaces are remove bucause it is implemented in
ivi-layout.c and set it as function pointer. Several interfaces are kept
here because they are implemented in ivi-layout.c/transition.c but used
in other files.

ivi-layout-transition.c:
remove WL_EXPORT because export is not needed anymore.
remove unnesesary unsed method.

ivi-shell.c:
call controller_module_init of hmi-controller to init it and set
function pointers. If the interface_version is equal or
greater than what hmi_controller was built with, things are pass.
If the interface_version is smaller than what the controller expects,
it has to fail because it cannot work. This is followed the manner,

- never remove a function pointer
- never modify an existing function signature
- additions are allowed at the end of struct ivi_controller_interface
- all function pointers must always be populated and working in
  ivi-shell.so (ivi-layout.c etc.)

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.

In-Vehicle Infotainment system traditionally manages surfaces with
