/**
* Log a message.
*
* If the DLL is being used in a WiX MSI environment, LogResult() will
* route any log messages to the MSI log file via WcaLog() or WcaLogError().
*
* If the DLL is NOT being used in a WiX MSI environment, LogResult() will
* route any log messages to stdout or stderr.
*
* If the result is an error code, LogResult will attempt to gather a
* text version of the error code and place it in the log. For example,
* if the error code means ERROR_FILE_NOT_FOUND, it will look up the appropriate
* message ( via FormatMessage() ) and add "The system cannot find the file specified."
* to the log.
*
* @param hr The HRESULT to be interrogated for success or failure.
* @param fmt The string format for a user-specified error message.
