9336263d9b Move libweston-desktop into libweston
It's not really useful to have libweston without libweston-desktop. It's
also very little code.

Merging both into the same DSO will allow us to cut out a bunch of
indirection and pain.

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.

16e3f27fc7 ivi-shell: bring back reference weston.ini
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.

4a378afa3b ivi-shell: Avoid unnecessary scaling of the view transformation matrix
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.

4b1de0112b build: add rpath to modules that use symbols from libexec_weston
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.

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.

71ff95a544 build: separate deps for int and ext libweston users
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.

4f5e360180 build: simplify include_directories
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.

6ef2d45a2d ivi-layout: unmap desktop surfaces in ivi_view_destroy()
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

 #include <compositor.h>

which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.

b81fc517d8 meson.build: Fix warning for configure_file
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.

building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.

More information at http://mesonbuild.com

Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.

This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.

It is expected that the autotools build system will be removed soon
after the next Weston release.

input_method protocol is no longer supported.
Therefore, we should remove it from the example config

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.

71f9ee1d22 ivi-shell: don't use input panel implementation
input panel implementation puts contents of an
application, which uses input_method protocol,
on top of all other surfaces. It is not controllable
with ivi-layout interface.

This is not acceptable for an In-Vehicle Infotainment
platform. Because we have to ensure configured scenegraph
cannot be hijacked by any rogue application.

Therefore, I am removing input panel implementation

d93a52a6f9 ivi-shell: check ivi_view mappedness in commit_changes()
If the view is not mapped, we do not need to update its
properties. We can use ivi_view_is_mapped() function to
check it.

Also we don't need to call weston_view_damage_below()
for weston_views, which were in the scenegraph. Because
we are calling weston_view_unmap for views of unmapped
ivi_views in build_view_list() function

f6638a7f0f ivi-shell: unmap views which are not in scenegraph
From Michael Olbrich:
"Both the core in weston_compositor_build_view_list() with view.link
and the ivi-shell in commit_screen_list() with view.layer_link
don't remove the old views from the list.

As a result, all views that are not currently in the list have
old broken links. Destroying such a view tries to remove
the view from these lists and will access the old, invalid pointers."

Therefore, we have to unmap weston_views which are not in current
scenegraph of ivi-shell. I implemented ivi_view_is_mapped() function
to check mappedness of ivi_views. The functions checks:
   - the view is on a layer's order list
   - the layer is on a screen
   - the layer and view's ivi_surface are visible

If ivi_view is not mapped but weston_view is still mapped,
we have to unmap the weston_view with weston_view_unmap() call.
