The __printflike attribute was added to catch issues with the calls related to printf(3) abuse. - Modify the code to facilitate the __printflike attribute addition. - Convert errf calls in to_mb(..) and to_mb_string(..) to warn(..) so the calls will return instead of exiting, as the code suggests it should.
