Go admin bindings fail to build

[cactorium]

Testing by checking out releases/1.5, releases/1.6, releases/1.7 and running go build from rescrv/HyperDex/bindings/go, I always get some error. For 1.5:

# github.com/rescrv/HyperDex/bindings/go/client
could not determine kind of name for C.hyperdex_client_document_atomic_add

# github.com/rescrv/HyperDex/bindings/go
./hypergo.go:95: undefined: req in req.status
./hypergo.go:97: undefined: req in req.success
./hypergo.go:98: undefined: req in req.success
./hypergo.go:101: undefined: req in req.failure
./hypergo.go:102: undefined: req in req.failure
./hypergo.go:102: undefined: req in req.status

./hypergo.go:107: undefined: req in req.failure
./hypergo.go:110: undefined: i
./hypergo.go:110: too many errors

Is there some flaw in how I'm building it? Didn't inspect 1.5 too well, but for 1.6 and 1.7 it looks like there's some form of for or while loop missing. I'll try to write a pull request to fix this
