Proof of Reporter concept: restore pointQuery and trackPointQuery

Only now it's "obvious" how they are the same and how they differ from
the basic loop:

* normalizedDistance is the only new feature added;
* all the rest is in reporter stuff...
* ... except that we have to turn on L2Norm, even if we don't use it.

Alter the tests to cope with this fact, l2norming the point- and
track-search databases.

   unsigned queryType; // point queries default
   unsigned pointNN;   // how many point NNs ?
   unsigned trackNN;   // how many track NNs ?
   unsigned sequenceLength;
   unsigned sequenceHop;
+  bool normalizedDistance;
   unsigned queryPoint;
   unsigned usingQueryPoint;
   unsigned usingTimes;
   unsigned usingPower;
   unsigned isClient;

   queryType(O2_POINT_QUERY), \
   pointNN(O2_DEFAULT_POINTNN), \
   trackNN(O2_DEFAULT_TRACKNN), \
   sequenceLength(16), \
   sequenceHop(1), \
+  normalizedDistance(true), \
   queryPoint(0), \
   usingQueryPoint(0), \
   usingTimes(0), \
   usingPower(0), \
   isClient(0), \
