This is a complete port of the headless 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. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.
