weston: Port Wayland backend to new output handling API This is a complete port of the Wayland backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. However, the backend can behave both as windowed backend and as a backend that issues "hotplug" events, when running under fullscreen shell or with --sprawl command line option. The first case was covered by reusing previously added functionality. The second case required another API to be introduced and implemented into both the backend and compositor for handling output setup. After everything has been set, output needs to be enabled manually using weston_output_enable(). v2: - Fix wet_configure_windowed_output_from_config() usage. - Call wayland_output_disable() explicitly from wayland_output_destroy(). v3: - Get rid of weston_wayland_output_api and rework output creation and configuration in case wayland backend is started with --sprawl or on fullscreen-shell. - Remove unneeded free(). - Disallow calling wayland_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). v4: - Drop unused fields from weston_wayland_backend_config and bump WESTON_WAYLAND_BACKEND_CONFIG_VERSION to 2. - Move output creation to backend itself when --fullscreen is used. - Prevent possible duplicated output names by assigning a different name to outputs created without any configuration specified.
