      BUG#36804 - Falcon does not detect deleted tablespace files
      
      Falcon silently recreates it's system data files if it wasn't
      able to open them. With this fix Falcon provides some
      additional information in error log.
      
      When starting mysql server with Falcon and we were unable
      to open Falcon system data files, write a warning to error
      log.
      
      Write an error message to error log when attempting to access
      a table that doesn't exist in Falcon.
