/* This function will execute both a vplog() and an vsendmqf() in order to
   report on an erroneous condition.
   It makes error returns easier.  It returns PFAILURE, since it should only be
   used if an error has occurred. 
   It also automatically prefixes the word ERROR to the error reply packets.
   It appends the appropriate newlines, so you don't have to.
