Functions
void	error_dump_string (const char *msg, char *buff, size_t buff_size)
static void	tls_free (void *val)
int	MLOG_init (MLOG_LEVEL current, MLOG_ACTION action, void *arg)
	explicitly initialises logging.
int	MLOG_alloc_option (MLOG_ALLOC option, size_t size)
	determines memory allocation stragegy used here
void	MLOG_dump_stack_level (MLOG_LEVEL level)
	set log level for which the current stack is dumped. By default this would happen for LOG_LEVEL_ERROR
int	MLOG_printf (MLOG_LEVEL current, const char *file, int line, const char *format,...)
	create a log entry, do not use this function directly, use MLOG_<LOG_LEVEL_NAME> macros instead
