    0023880: Integration of grid "ncl" into the new testing system
    
    Function perf_sprint_all_meters added in OSD_PerfMeter.h to allow printing to string buffer rather than stdout. Macro PERF_PRINT_ALL converted to functional form.
    
    Command dperf added in DRAW to print and conditionally reset all meters.
    Description of these tools is added in Debug Hints.

I have pushed fix that extends OSD_PerfMeter with possibility to get results to string, and QANColPerf* commands to output to DRAW, to branch CR23880_3.

The tests are also available, however I do not integrate them since they use fixed numbers for expected CPU values and thus are bound to particular hardware. I deem it would be more correct to compare performance of OCCT classes against equivalent STL classes, see command QANTestNCollectionPerformance. The parameter to be controlled would be ratio of performance and it can be expected to less depend on hardware.

    Modified output of command QANTestNCollectionPerformance.
    Added test case perf/ncollection/A1

Test case which control ratio of performance between OCCT classes against equivalent STL classes was created.
perf ncollection A1 - OK

Please, review.

Reviewed, please test

Ratio of performance was corrected according to test case behavior on virtual machines.
Please, review.

No remarks, please test (I suppose that executing updated test perf ncollection A1 on previously built branch should be sufficient)
