The ivi-shell keeps track of its surfaces by adding them to the ivi_surface_list
to be able to remove them on shutdown. It also creates an ivi_layout_surface for
a desktop surface, but does not keep track of these surfaces.
During compositor shutdown, libweston prints the following message:
BUG: finalizing a layer with views still on it.
Fix it by adding the created ivi_layout_surface to the ivi_surface_list to
remove the surfaces from the layer during shutdown.
Furthermore, remove the ivi_layout_surface from the desktop surface and free it
when the desktop surface is destroyed.

If a controller requests the layers under a surface that has no views attached,
Weston crashes since it tries to free the array that would be used to return the
found layers, but has not been allocated before.
Free the ppArray only if it was allocated in ivi_layout_get_layers_under_surface
before and no layers were found.
While at it, make it obvious that checking the length is an integer comparison
by comparing it to 0.

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().

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

In commit d8e09afc9f ("tests: Convert ivi-shell-app-test.c to use
`weston_ini_setup`") the reference weston.ini for the ivi-shell was
removed, because it is not required by the test anymore.
The reference weston.ini still has value as an example for the ivi-shell
and how the ivi-shell-user-interface has to be configured. Retrieving
this information from the test case is not intuitive. Furthermore, the
file is still referenced by the ivi-shell/README, and the
configuration_data for generating the file was not fully removed.
Bring back the reference weston.ini for the ivi-shell and, while at it, cleanup
the configuration_data() to define only keys that are actually used in
weston.ivi.in.

The opaque region of a weston view is updated only if the alpha value is 1
and the transform matrix is of type WESTON_MATRIX_TRANSFORM_TRANSLATE.
While using ivi-shell, opaque region is never updated, as we are performing
scaling operations to the view transform matrix, even when the scaling
factor is 1 and thereby changing the type to WESTON_MATRIX_TRANSFORM_SCALE.
Perform scaling of the view transformation matrix only when the scaling
factor is non-zero.

The cms-static, desktop-shell, hmi-controller, ivi-shell, and screen-share
modules use symbols from libexec_weston, e.g.:
$ ldd /usr/lib/x86_64-linux-gnu/weston/desktop-shell.so | grep "not found"
libexec_weston.so.0 => not found
Loading these modules from weston happens to work because the weston executable
itself links against libexec_weston, and has an rpath set. Still, these modules
depend on a library in a non-standard location. Adding an rpath could help
static checkers to make sure all shared objects' dependencies are present.

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.

We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.

weston_desktop_surface_unlink_view() does now call weston_view_destroy() so the
weston_view is not destroyed here. This is a problem because the view remains in
the weston_layer view_list. If ivi_view_destroy() is called from
ivi_layout_surface_destroy() and the view list is rebuilt in the 'removed'
signal, then the list gets corrupted when the view is destroyed immediately
afterwards.
Fix this by calling weston_view_destroy() unconditionally for all view.

The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain

which is prone to name conflicts. This is reflected both in the installed

same form as an external project using libweston would.

We claim to support meson versions >= 0.47 but the `install:` argument
in configure_file was introduced in version 0.50. This produces the
following meson warning:
WARNING: Project specifies a minimum meson_version '>= 0.47' but uses
features which were added in newer versions:
* 0.50.0: {'install arg in configure_file'}
From the documentation for the install argument [1]:
" When omitted it (install) defaults to true when install_dir is set and
not empty, false otherwise."
So, remove the `install:` argument and just depend on `install_dir` for
installing.
