revlog: abort on attempt to write null revision
My repo got corrupted yesterday by something that ended up writing the
null revision to the revlog (nullid hash, not nullrev index, of
course). We use many extensions internally (narrowhg, remotefilelog,
evolve, internal extensions) and treemanifests are on. The null
revision was written to the changelog, the root manifest log, and one
subdirectory manifest log. I have no idea exactly why the null
revision was written, but it seems cheap enough to check that we
should fail instead of corrupting the repo.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
