Currently the top level directory contains basically all of the code for the crypto package. This PR moves the crypto code into submodules in a similar manner to what `golang/x/crypto` does. This improves code organization. Ref discussion: https://github.com/tendermint/tendermint/pull/1966 Closes #1956
