So, I've changed stuff around to PANIC only as soon as we're in a state
that's unclear.
To test stuff I've added another .so to the test_decoding contrib that
exposes mkdir/rmdir/chmod/unlink to sql to test those cases in the
contrib's sql/slot.sql. Not sure if we want to keep that, but it's
certainly helpful for now.
The required changes certainly didn't make things look nicer...

I've also changed the temporary name used when creating/dropping slots
to $slotname.tmp.

That doesn't remove PANICs but makes them even less likely. Ok?
