1ffcc535ef hmi-controller: Do not call hmi_controller_destroy() from _create()
Move the destroy listener registration to the top, to avoid having
to call hmi_controller_destroy() for cleanup when it fails.

This would segfault trying to remove the destroy listener from a list
when its link was never initialized or inserted into any list.

The failure case can be hit by setting both modules=hmi-controller.so in
weston.ini and --modules=hmi-controller.so on the command line.

3805bcad90 hmi-controller: prepare for API simplification
The return values for most of the API functions will be removed and replaced by
asserts. So remove the return value checks. The end result will be the same:
These functions only fail for incorrect API usage, so basically the asserts are
moved from the hmi-controller into the shell.

cbbf0e59a5 ivi-shell: replace MEM_ALLOC() with mostly xcalloc()
Drop the even more home-grown alloc wrapper and use the xalloc.h
wrappers directly.

xcalloc() is added and used, because calloc() will detect integer
overflows in the size multiplication, while doing a simple
multiplication in the caller is subject to overflows which may result in
allocating not what was expected, subjecting to out-of-bounds access.

All MEM_ALLOC() calls that had a meaningful multiplication in them were
converted to xcalloc(), the rest to xzalloc().

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.

d97f10081e ivi-shell: add surface_created listener after launchers
Add surface_created listener after the initialization of launchers.
Otherwise, surfaces of the launchers will be added to the application
layer too.

This does create a race where we might miss some surfaces that get
created before the UI client signals ready, but it was agreed the race
is not significant. You cannot use the launchers before the UI is ready,
and someone using systemd integration to launch clients in parallel to
Weston with ivi-shell and hmi-controller is unlikely. After all,
hmi-controller is just a demo.

58f98c99f5 Move weston source to compositor/
This is the start of separating weston-the-compositor source files from
libweston source files.

This is moving all the files related to the 'weston' binary. Also the
CMS and systemd plugins are moved.

xwayland plugin is not moved, because it will be turned into a
libweston feature.

To avoid breaking the build, #includes for weston.h are fixed to use
compositor/weston.h. This serves as a reminder that such files may need
further attention: moving to the right directory, or maybe using the
proper -I flags instead.

v2: Move also screen-share.c, and add a note about weston-launch.
