Josh Bleecher Snyder a5dd0bcb09 util/jsonutil: new package
The cornerstone API is a more memory-efficient Unmarshal.
The savings come from re-using a json.Decoder.

BenchmarkUnmarshal-8      	 4016418	       288 ns/op	       8 B/op	       1 allocs/op
BenchmarkStdUnmarshal-8   	 4189261	       283 ns/op	     184 B/op	       2 allocs/op

It also includes a Bytes type to reduce allocations
when unmarshalling a non-hex-encoded JSON string into a []byte.

Josh Bleecher Snyder 9784cae23b util/uniq: add new package
This makes it easy to compact slices that contain duplicate elements
by sorting and then uniqing.

This is an alternative to constructing an intermediate map
and then extracting elements from it. It also provides
more control over equality than using a map key does.
