scanner: add a new --include-core-only option
When using this new option the generated code will include the new core headers instead of the old ones. The default needs to remain unchanged for backward compatibility with old code. With this change the generated headers will now forward declare all types and interfaces it uses; that is needed when generating headers for a my-extension.xml with --include-core-only, since it may use types defined in wayland.xml. The same is done also without --include-core-only, since it is an harmless change. getopt_long() is used for the option handling. Reviewed-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
