tests: add a metaclass for triggering stupid on a class level
We use a metaclass similar to the tests for obsolete mode. This
metaclass deliberately duplicates each test for each mode; enabling
both means that each test function is run four times.
This makes it less likely that a fix is accidentally applied to replay
mode only, as new tests will often automatically cover both
modes. However, as certiain features remain deliberately unimplemented
in stupid modes -- filemaps being a notable example -- we also add a
decorator function for marking methods testing them.
We do this for reasons of both consistency and coverage; we avoid
littering the tests with *_stupid variants, and thus are less likely
to forget adding them. I already found a couple of bugs in stupid mode
thanks to this increased coverage.
