1) PVRecord now has two new methods: setAsLevel and setAsGroup.
2) The following special records are DEPRECATED: addRecord,processRecord,removeRecord, and traceRecord.
They are replaced by pvdbcrAddRecord,pvdbcrProcessRecord,pvdbcrRemoveRecord, and pvdbcrTraceRecord.
3) A new convention is that all special records start with pvdbcr, which means pvDatabase Create Record.
4) pvdbcrAddRecord,pvdbcrProcessRecord,pvdbcrRemoveRecord, and pvdbcrTraceRecord are like what they replace.
But they also allow the asLevel to be set when they are created.
5) pvdbcrScalar and pvdbcrScalarArray are new special records.
They created records that have fields value, alarm, and timeStamp.
value can have any of the allowed scalar types, i.e. boolean,byte,...,string.
