  style(9): sort headers
  
  r318278:
  
  Mark errf _Noreturn, and mark errf and warn __printflike
  
  The _Noreturn attribute was added to placate Coverity and other static
  analysis tools. 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.
