Audit logname(1)
1) Add usage(). 2) Idiomatic argv0-setter. We don't use arg.h, as we do not process flags or arguments. 3) Remove program-name from eprintf-call. This is done in the eprintf- function itself when the DEBUG-define is set. We'll activate it by default later. 4) Add empty line before return.
