Introduce advise() to print hints
Like error(), warn(), and die(), advise() prints a short message with a formulaic prefix to stderr. It is local to revert.c for now because I am not sure this is the right API (we may want to take an array of advice lines or a boolean argument for easy suppression of unwanted advice).
