dirstate-v2: add check of parent/child nodes being related when writing
This stems from a corruption seen in a private repository. We're not sure
of the source of the corruption, and it's very possible that we're seeing
compounded effects of multiple writes on a corrupted dirstate.
Adding this check is not expensive in itself and large writes of the dirstate
are not common.
This change does not catch this problem at the root node, the next one will.

persistent-nodemap is not enabled by default. It is not relevant for this test so disable it.

Helper function to run protocol tests against multiple protocol versions.
This is easier than using #testcases because managing differences between
protocols with inline conditional output is hard to read.
