Merge #15296: tests: Add script checking for deterministic line coverage in unit tests 
43206239a8 tests: Add script checking for deterministic line coverage (practicalswift)

Pull request description:

  Add script checking for deterministic line coverage in unit tests.

  Context: #14343 ("coverage reports non-deterministic")

  When the coverage is deterministic this script can be invoked from Travis to guard against regressions, but left inactive for now.

  Output in case of determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  Coverage test passed: Deterministic coverage across 2 runs.
  ```

  Output in case of non-determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  The line coverage is non-deterministic between runs.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a neccessary condition for meaningful coverage
  measuring.

  In this case line 363 of `test/denialofservice_tests.cpp` was executed only in the second run. Non-determinism detected!
