Function test measurement: precision and API's Function-test of the ultimate purpose of this project. Contains several new files as technique for automatic-testing temporal behaviour reliably requires much more work and diligence than "normal" function-tests. As timeliness and measuring there-of is the primary function for this project, the extra work and divergence from perceived common ways, are motivated and necessary. Goals and function: * Measurements. Is service executing within expected tolerances? * API setting-up, running and harvesting dprobes results * POC for function tests for other utrace supported c-projects * Calibrating expectations and evaluation methods such that test has a reasonable chance to succeed on other targets. The challenge is in the tightest loop of the demonstrating-/test-program, which is free-running full speed without sleeps or volunteer context switches.
