/*
  Logging facilities.

  Two logging streams are supported: error log and info log. Additionally
  libdbug may be used for debug information output.
  ANSI C buffered I/O is used to perform logging.
  Logging is performed via stdout/stder, so one can reopen them to point to
  ordinary files. To initialize loggin environment log_init() must be called.

  Rationale:
  - no MYSQL_LOG as it has BIN mode, and not easy to fetch from sql_class.h
  - no constructors/desctructors to make logging available all the time
  Function names are subject to change.
