* add sync method: Since file systems tend to have a inbuild caching mechansim we need to sync these caches at the end of session when using the fuse_fs server. Therefore each FUSE file system port has to implement a Fuse::sync_fs() function that executes the necessary actions if requested. * add symlink check * allow to check FUSE fs initialization This changes the private API of the FUSE implementation. The init_fs method now has to return true if the initialization was successful and otherwise false. All current users of the API are also changed accordingly. Fixes #1058.
