Support EIP-1898

[gzliudan]

XinFin blockchain does not support EIP-1898 now. Below methods are are affected:

• eth_getBalance
• eth_getStorageAt
• eth_getTransactionCount
• eth_getCode
• eth_call

Here is a test case, request:

curl -X POST https://arpc.apothem.network/ -H "Content-Type: application/json" -d '
{
    "id": 348,
    "jsonrpc": "2.0",
    "method": "eth_call",
    "params": [
        {
            "data": "0x06fdde03",
            "gas": "0x2faf080",
            "to": "0x53350795c11cee781a7e174479778f848d76ab2a"
        },
        {
            "blockHash": "0xe8ec0bfc021f839fd0a69ae89689e309632af2cc434e8a096732068f0736864b"
        }
    ]
}'

And the response is:

{
  "jsonrpc": "2.0",
  "id": 348,
  "error": {
    "code": -32602,
    "message": "invalid argument 1: hex string without 0x prefix"
  }
}

@gzliudan - XDC Network has recently implemented XIPs and this is a perfect example of one that can be written / copied over from the EIP. Please check https://www.xdc.community/pages/xips/ and learn how to contribute and use the template to generate the XIP. I will be happy to support the process if you would like to champion it through.
