Log skeletons for queries in server (live from parser) but without constants with statistics. Things to consider: * Should use a fixed memory size. Queries should be removed as FIFO * Small CPU overhead * IN(a,b,c) should be equal recorded as IN(#) (One constant) * multi row inserts needs to be handled as one insert. We also need a method to do regular expression replacement for table names. This is needed to be able to recognize similar tables like log tables with a _YYMMDD prefix. Statistics to collect per query: - Number of times executed - Total time executed (in microseconds) - Rows read, inserted, updated and deleted.
