Creates a directory. Note that this will only create a child directory
of the immediate parent directory of the path or URI given by the GFile.
To recursively create directories, see g_file_make_directory_with_parents().
This function will fail if the parent directory does not exist, setting
error to G_IO_ERROR_NOT_FOUND. If the file system doesn't support
creating directories, this function will fail, setting error to
G_IO_ERROR_NOT_SUPPORTED.
For a local GFile the newly created directory will have the default
(current) ownership and permissions of the current process.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
