This changes storage.mount() to require that a mount point exist on the parent file system. A bug in background tasks is also fixed where the function parameter is cleared on pending callbacks during "reset". Disk usage is shown on the directory listing and changes based on the mounted file system. Writable is also loaded per-directory. Fixes #8108. Fixes #8690. Fixes #8107.
