  Log:
  Merge audit_worker.c:1.12 from HEAD to RELENG_6:
  
    Rework the way errors are handled with respect to how audit records are
    written to the audit trail file:
  
    - audit_record_write() now returns void, and all file system specific
      error handling occurs inside this function.  This pushes error handling
      complexity out of the record demux routine that hands off to both the
      trail and audit pipes, and makes trail behavior more consistent with
      pipes as a record destination.
  
    - Rate limit kernel printfs associated with running low on space.  Rate
      limit audit triggers for low space.  Rate limit printfs for fail stop
      events.  Rate limit audit worker write error printfs.
  
    - Document in detail the types of limits and space checks we perform, and
      combine common cases.
  
    This improves the audit subsystems tolerance to low space conditions by
    avoiding toasting the console with printfs are waking up the audit daemon
    continuously.
