<dt>Summary</dt>
<dd>This function allows to log arbitrary messages even in a product-environment.
</dd>
<dt>Description</dt>
<dd> 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.
