Try replacing all duplicate checks with validateCallback, Due to the scope of the changes, it may be necessary to run a benchmark.

Definitely not for this PR, but for what it's worth, I'd be in favor getting rid of ERR_INVALID_CALLBACK entirely and using ERR_INVALID_ARG_TYPE instead. It is very difficult for me to imagine a situation where ERR_INVALID_CALLBACK is more useful to someone than ERR_INVALID_ARG_TYPE. On the other hand, it is easy for me to imagine a situation where someone has to check for both ERR_INVALID_ARG_TYPE and ERR_INVALID_CALLBACK but they don't know it and they're only checking for ERR_INVALID_ARG_TYPE. Node.js has too many error codes and they are often not specific in a way that is helpful to end users. ERR_INVALID_CALLBACK seems to be one of those cases.

Thanks for the reply, very valuable thought. node.js does have too many error codes, I was confused when I first opened the error.js file too.

ERR_INVALID_CALLBACK and ERR_INVALID_ARG_TYPE are also duplicates, and I personally agree with using ERR_INVALID_ARG_TYPE for both.

However, ERR_INVALID_CALLBACK being a widely used error code, replacing it with ERR_INVALID_ARG_TYPE may cause compatibility issues. Perhaps we can replace it with ERR_INVALID_ARG_TYPE in the next major release?
