Michael Sproul 7aceff4d13 Add safe_sum and use it in state_processing (#1620) ... ## Issue Addressed Closes #1098 ## Proposed Changes Add a `SafeArithIter` trait with a `safe_sum` method, and use it in `state_processing`. This seems to be the only place in `consensus` where it is relevant -- i.e. where we were using `sum` and the integer_arith lint is enabled. ## Additional Info This PR doesn't include any Clippy linting to prevent `sum` from being called. It seems there is no existing Clippy lint that suits our purpose, but I'm going to look into that and maybe schedule writing one as a lower-priority task. This theoretically _is_ a consensus breaking change, but it shouldn't impact Medalla (or any other testnet) because `slashings` shouldn't overflow!		2020-09-22 05:40:04 +00:00
