Missing commas with SQL log4cpp logging format

[Anuradha]

 During UDF testing an issue was found with SQL log4cpp logging format where there were some missing commas

I'll try to fix this in R1.0, may update the milestone. If we don't make it, the UDF is tolerant of the missing commas and should still provide reasonable information.

The two missing commas are for SQLCode and QueryId. The fix is to provide two QRLogger::log methods. One just takes a message and puts two NULL values (",,") for these two items into the log file. The second method has two more parameters, SQLCode and QueryId and allows the caller to log actual values for these. There are hundreds of calls to the first method in our code and only a handful of calls to the second method.
