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.

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

Modified ratio of performance to check all platforms

Small correction of test-case for Windows platform
