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).
