GetUnclaimedGas Generic

[vncoelho]

Perhaps we need extra calls on RPCServer plugin such as generic GetUnclaimedGas call apart of just the the one linked to the wallet itself:

neo-modules/src/RpcServer/RpcServer.Wallet.cs

Lines 71 to 81 in d62b18b

	private JObject GetUnclaimedGas(JArray _params)
	{
	CheckWallet();
	BigInteger gas = BigInteger.Zero;
	using (SnapshotView snapshot = Blockchain.Singleton.GetSnapshot())
	foreach (UInt160 account in wallet.GetAccounts().Select(p => p.ScriptHash))
	{
	gas += NativeContract.NEO.UnclaimedGas(snapshot, account, snapshot.Height + 1);
	}
	return gas.ToString();
	}

The one linked to the account should be something like GetWalletUnclaimedGas

IMO this call should just be extended to work with any addresses, getting this data is so cheap on Neo 3 that limiting this method to wallet-only addresses makes no sense to me. And I don't think we need two methods here, one working for any address is enough.

In fact, that's the model neo-go uses for getunclaimed on Neo 2, answering this call for any addresses known to the chain and it works fine (even though it costs something in terms of additional UTXO tracking).

Agree with you @roman-khimov
