Add clang-tidy and splint static analytics check. For now, we use only the cert-* warnings on clang-tidy and run splint with a lot of flags to allow more things. Changes to silence these analytics: - Stop returning stuff from our debug print functions. We don't check them anyway and we don't have any way of detecting transmission failure. - Declare more things static that isn't used outside of a file. - Change types to be more consistent, typically to size_t or something or to uint32_t.
