QEvent: document and check when registerEventTypes() returns -1
In tst_QEvent, add a check that exhausts the available event type ids and verifies
that registerEventTypes() returns -1 in that case, as documented.
I haven't found a way to test the other case in which -1 is returned.
Since this test operates on a global write-only registry the new test case needs
to keep track of whether the earlier test cases have run successfully. If they
didn't, skip this test case.
