    demux: update log lines
    
    Rather than rely on CUR_FROM magic (which is only set after MD is
    created), use plog_from() and explictly specify the sender when
    errors.
    
    Also replace LOG_ERRNO with more direct PRI_ERRNO and use dbg() more.

    logging: add PRI_ERRNO/pri_errno(saved_errorno)
    
    More generan then LOG_ERRNO(), for instance:
      dbg("oops! "PRI_ERRNO, pri_errno(saved_errno));
