+  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 may be performed in two modes: 
+  - console application mode (default), stdout/stderr is used for logging
+  init_logs() must be called to initialize logging environment
+  - daemon mode, without controlling terminal, call
+  init_logs_in_daemon_mode() to initialize
+  
+  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.
