Merge #14685: fix a deserialization overflow edge case
b08af10fb299dc3fdcd1f022619fb112c72e5d8e disallow oversized CBlockHeaderAndShortTxIDs (Kaz Wesley)
6bed4b374daf26233e96fa7863d4324a5bfa99c2 fix a deserialization overflow edge case (Kaz Wesley)
051faf7e9d4e32142f95f7adb31d2f53f656cb66 add a test demonstrating an overflow in a deserialization edge case (Kaz Wesley)
Pull request description:
A specially-constructed BlockTransactionsRequest can cause `offset` to wrap in deserialization. In the current code, there is not any way this could be dangerous; but disallowing it reduces the potential for future surprises.
