Results were difficult to interpret because the counts during the high priority, budget interval were included with other counts during the low priority interval. This corrects that reporting by using two counts: One for the low and one for the high priority interval. This makes the results much easier to interpret.
There should be no impact to anything other that the sporadic scheduler case of the OS test.
Tested using the the stm32f4discovery:sporadic configration. That configuration has no yet been merged but is available from incubator-apps PR 3097.
This commit adds the test developed by Jan Staschulat with Issue #incubator_nuttx/2935
It is expected to cause the OS test to fail for the time being since that issue reports a bug.
Tested using the (new) stm32f4discovery:sporadic configuratioin.
