  Logger does not warn of failure to open logging channels

  Currently, logger only prints an error message to stderr when it fails to open
  a logger channel where many users will not see it because the logger lock is
  held.  The alternative provided by this patch is to log the error to all
  attached consoles in the hopes that it will be easier to see.  Additionally,
  this patch prevents the failed logger channel from being added to the list
  where it would silently fail on each call to the Asterisk logger.

  (closes issue ASTERISK-16231)
