QTestLib: add a abort-on-fail environment variable
When debugging a spurious failure it's extremely useful to
run the test repeadtly into a debugger until a failure appears.
When that happens, one wants to immediately start debugging.
In so far, this has only been possible by placing breakpoints
inside Qt itself (when a failure is logged). Add another way:
an env variable, similar to QT_FATAL_WARNINGS, that makes
any failure fatal (terminate() gets called. Bonus: you can
control the termination handler!)
[ChangeLog][QtTestLib][QtTest] When the QTEST_FATAL_FAIL
environment variable is set to a non-zero value, a test
immediately aborts its execution. This is useful to debug
intermittent failures.
