nethack/src/sit.c
PatR 9c422f2c1f fix #H7707 - terrain change leaving stale flags 
struct rm.flags in overloaded for a bunch of rm.typ -dependent things
(doormask, altarmask, throne/fountain/sink looted, a few others) and
wasn't being reset for various cases where rm.typ gets changed.

I've changed a lot, some no doubt unnecessarily, and probably missed
plenty.  This compiles but has not been thoroughly tested.
