How about adding our license comment?

Then we need to decide on a license declaration for our new files. I'll save it as another discussion ticket.

How about collecting all similar constant values like below?
const (
PUBLICKEYBYTES = uint32(C.crypto_vrf_PUBLICKEYBYTES)
SECRETKEYBYTES = uint32(C.crypto_vrf_SECRETKEYBYTES)
SEEDBYTES = uint32(C.crypto_vrf_SEEDBYTES)
PROOFBYTES = uint32(C.crypto_vrf_PROOFBYTES)
OUTPUTBYTES = uint32(C.crypto_vrf_OUTPUTBYTES)
PRIMITIVE = C.crypto_vrf_PRIMITIVE
)

Yes, it seems better readability. I'll fix it.

I think it's better to move topside, because it is easy to understand that the constant and property values is collected and are existed topside than functions.

This PR on #1, #2 allows us to call the library
libsodiumimplemented in C from within the Tendermint project. This contains golang functions that are equivalent to the VRF functions defined inlibsodium.Note that the
libsodiumused in this PR is a cryptography library of the same name with VRF capability (IRFT Draft 3) added by Algorand. The original libsodium does not contain a VRF.In a newly checked out environment, libsodium must be built and installed before compiling golang.
This PR is a renewed version of #4 with accumulated commits and rebases.
