This enables the following linters - typecheck - unused - staticcheck - bidichk - durationcheck - exportloopref - gosec WIth a few exceptions. - We use a deprecated protobuf in trezor. I didn't want to mess with that, since I cannot meaningfully test any changes there. - The deprecated TypeMux is used in a few places still, so the warning for it is silenced for now. - Using string type in context.WithValue is apparently wrong, one should use a custom type, to prevent collisions between different places in the hierarchy of callers. That should be fixed at some point, but may require some attention. - The warnings for using weak random generator are squashed, since we use a lot of random without need for cryptographic guarantees.
