/**	This function allows to log arbitrary messages even in a product-environment.

	The logfile is created on first access and closed, when the sal-library gets unloaded.
	The file is line buffered. A log file is not created if no log messages are
	written.

	The first time, rtl_logfile_trace is called, it checks for the bootstrap variable
	RTL_LOGFILE. If the variable is not empty, it creates a file with the name
	$(RTL_LOGFILE)_$(PID).log, where $(PID) is the process id of the running process.

	@param pszformat A format string with fprintf-syntax
	@param ...       An arbitrary number of arguments for fprintf, matching the
	                 format string.
