Add QTest option for repeating the entire test execution

Repeated test execution can be useful, under a debugger, to catch an
intermittent failure or, under memory instrumentation, to make memory
leaks easier to recognize.

The new -repeat flag allows running the entire test suite multiple times
within the same process. It works by executing all tests sequentially
before repeating the execution again.

This switch is a developer tool, and is not intended for CI. It can only
be used with the plain text logger.
