Simplify struct, map, array and slice literals

Such a simplified formatting helps to improve code readability.

Thanks! However, most of those files touched are auto-generated, so we would need to fix the generators that create these files in order to accept this patch.

Running make generate and make generate-protocol-test should show you what's been overwritten.

There is no magic behind this PR. I just run the gofmt -s -w command at the top of the repository.

Oh, I didn't know that. Is there a good reason to keep such a generated files in the repository?

[lsegal]

Go generate is never run automatically by go build, go get, go test, and so on. It must be run explicitly.

Unfortunately because of this rule in go generate.

I fixed the commit. I took away the files which are generated. I hope it's ok now.
