This adds support for EIP-2718 typed transactions as well as EIP-2930
access list transactions (tx type 1). These EIPs are scheduled for the
Berlin fork.
There very few changes to existing APIs in core/types, and several new APIs
to deal with access list transactions. In particular, there are two new
constructor functions for transactions: types.NewTx and types.SignNewTx.
Since the canonical encoding of typed transactions is not RLP-compatible,
Transaction now has new methods for encoding and decoding: MarshalBinary
and UnmarshalBinary.
The existing EIP-155 signer does not support the new transaction types.
All code dealing with transaction signatures should be updated to use the
newer EIP-2930 signer. To make this easier for future updates, we have
added new constructor functions for types.Signer: types.LatestSigner and
types.LatestSignerForChainID.
This change also adds support for the YoloV3 testnet.

* accounts/scwallet: use go-ethereum crypto instead of go-ecdh
github.com/wsddn/go-ecdh is a wrapper package for ECDH functionality
with any elliptic curve.
Since 'generic' ECDH is not required in accounts/scwallet (the curve is
always secp256k1), we can just use the standard library functionality
and our own crypto libraries to perform ECDH and save a dependency.
