Another heap-user-after-free, this time we were missing a fix that had been applied to server.h but not config_validation/server.h (envoyproxy#4940). While working on this, attempted to make fully consistent and as simple/clear as possible the constraints on member ordering. This PR is in the tradition (!) of envoyproxy#5847, envoyproxy#4940, envoyproxy#4937. I think long-term we might want to think of more dynamic and explicit declaration of ordering constraints, it's evidently pretty fragile. Also, the lack of single-source-of-truth and duplication across prod and config server code bites again. Fixes oss-fuzz issue https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13228. Risk level: Low Testing: Corpus entry added. Signed-off-by: Harvey Tuch <htuch@google.com>
