Replace OFFSET_OF macro with a function template

(in preparation of extending loplugin:redundantcast to more reinterpret_cast
scenarios, which would have caused a false positive here).  Required a tweak to
loplugin:fakebool (as the relevant reinterpret_cast to silence some occurrences
is no longer seen "inline" now), and the heuristics of loplugin:unused no longer
worked (also because of the now-hidden reinterpret_cast'ing), but adding a
maybe_unused attribute looks better than tweaking that plugin's heuristics even
further.
