Martin Hořeňovský 3f8cae8025 Add consistency-checking event listener to SelfTest ...

This event listener performs basic consistency checks (akin to
matching braces) on events that are passed to the listeners
when the `SelfTest` test binary is run.

The current checks are about nesting events (e.g. `testCaseStarting`
cannot be received before `testRunStarting`, `sectionStarting`
can only be received when a test case is active, etc), and matching
up counts of starting/ended events.

The simplicity means that it could be confused by starting/ended
events matching up but being out of order, e.g.
```
* test case A starting
* test case B ended
* test case B starting
* test case A ended
```
would be accepted, even though it is wrong. However, doing full
order checking would be much more implementation work, for relatively
little benefit, so it is left out for now.
