Markus Unterwaditzer 275a3f8636 [chore] Upgrade golangci-lint, ignore existing int overflow warnings
There is a new lint for unchecked int casts. Integer overflows are bad,
but the old code that triggers this lint seems to be perfectly fine.
Instead of disabling the lint entirely for new code as well, grandfather
in existing code.
