* Factored a ProfilerStandard class out of Profiler * Profiler is now an abstract base class * For b/c, using Profiler as the profiler switches to ProfilerStub to avoid trying to instantiate an abstract class * Also factored out a small TransactionProfiler class * Fixed fatal in "new ProfilerStub()" line in getInstance(); Profiler has long since type hinted $params as an array * Removed bogus debug var usage left in ProfilerMwprof::getRawData() * Removed useless mTimeMetric stuff Change-Id: I854dabba6c8b1fb7d92baca59ebd4af25878d11d
