This refactors transform_todos() to work on a todo_list. The function
is renamed todo_list_transform().
As rebase -p still need to check the todo list from the disk, a new
function is introduced, transform_todo_file(). It is still used by
complete_action() and edit_todo_list() for now, but they will be
replaced in a future commit.
todo_list_transform() is not a static function, because it will be used
by edit_todo_list() from rebase-interactive.c in a future commit.
