Fixes tendermint/tendermint#3439
* make sure we create valid private keys:

 - genPrivKey samples and rejects invalid fieldelems (like libsecp256k1)
 - GenPrivKeySecp256k1 uses `(sha(secret) mod (n − 1)) + 1`
 - fix typo, rename test file: s/secpk256k1/secp256k1/

* Update crypto/secp256k1/secp256k1.go

crypto

crypto is the cryptographic package adapted for Tendermint's uses

Importing it

To get the interfaces, import "github.com/tendermint/tendermint/crypto"

For any specific algorithm, use its specific module e.g. import "github.com/tendermint/tendermint/crypto/ed25519"

If you want to decode bytes into one of the types, but don't care about the specific algorithm, use import "github.com/tendermint/tendermint/crypto/amino"

Binary encoding

For Binary encoding, please refer to the Tendermint encoding spec.

JSON Encoding

crypto .Bytes() uses Amino:binary encoding, but Amino:JSON is also supported.

Example Amino:JSON encodings:

ed25519.PrivKeyEd25519     - {"type":"954568A3288910","value":"EVkqJO/jIXp3rkASXfh9YnyToYXRXhBr6g9cQVxPFnQBP/5povV4HTjvsy530kybxKHwEi85iU8YL0qQhSYVoQ=="}
ed25519.PubKeyEd25519      - {"type":"AC26791624DE60","value":"AT/+aaL1eB0477Mud9JMm8Sh8BIvOYlPGC9KkIUmFaE="}
