  20   Logging facilities.
  21
  22   Two logging streams are supported: error log and info log.
  23   Additionally libdbug may be used for debug information output.
  24
  25   ANSI C buffered I/O is used to perform logging.
  26
  27   Logging is performed via stdout/stder, so one can reopen them to point to
  28   ordinary files. To initialize logging environment log_init() must be called.
  29
  30   Rationale:
  31   - no MYSQL_LOG as it has BIN mode, and not easy to fetch from sql_class.h
  32   - no constructors/desctructors to make logging available all the time
