rev-list: detect broken root trees
When the traversal machinery sees a commit without a root tree, it assumes that the tree was part of a BOUNDARY commit, and quietly ignores the tree. But it could also be caused by a commit whose root tree is broken or missing. Instead, let's die() when we see a NULL root tree. We can differentiate it from the BOUNDARY case by seeing if the commit was actually parsed. This covers that case, plus future-proofs us against any others where we might try to show an unparsed commit.
