Currently doesn't exist a standard way to write a weston.ini inside a test. Here, two new functions `weston_ini_setup` and `cfgln` are introduced to help the test writer to write a weston.ini file and load it to the test. And `internal-screenshot-test` is converted to use the new method of write a weston.ini. This conversion serves as example and initial API test. The tester needs to call `weston_test_harness_execute_as_client` or `weston_test_harness_execute_as_plugin` in the same way as before. The `weston_ini_setup` will fill the setup->config_file with the correct path to the weston.ini file. The main design goal is to avoid pre-made or build-made weston.ini(s) and keep the test as self-contained as possible.
