* 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

* Merged the "collate at end" and "running collate" logic
into the base class to make it more unified and consistent.
* Pulled out DB code into ProfilerSimpleDB class.
* Removed the ProfilerSimple class and updated child classes.
* Made ProfilerSimpleTrace set the debug information too.
* Work around "ended by close()" bug from 99aef03f. Since the
getRawData() method gets called while some wfProfileOut() calls
have not yet happened, make it use the matched call data and let
the final logData() method work on the full data as normal.
* Let ProfilerSimple classes use getFunctionReport() for the profiler
debug log if it is setup instead of making it just return "".
* Made getRawData() work as best as possible with ProfilerMwprof.
* Removed $wgProfileToDatabase since it is now useless.
* Improved DB profile performance with sqlite.
* Updated visibility of various methods.
