* GetBlockTemplate RPC client implementation
* Txid added to the getblocktemplate result
* Omitempty for TxID and improved comment for GetBlockTemplate 'rules' field
Without this, users of this library wouldn't be able to issue GetBlock
requests to nodes which haven't updated to support the latest request
format, namely the use of a single `int` parameter to denote verbosity
instead of two `bool`s.
This change makes btcd's getblock command match bitcoind's. Previously
the default verbosity was 0, which caused errors when using the
rpcclient library to connect to a bitcoind node - getblock would
unmarshall incorrectly since it didn't expect a verbosity=1 result when
it did not specify verbosity.
Refactor GetBlockVerboseResult into two separate types: one type for getblock "hash" verbosity=1,
and a second type for getblock "hash" verbosity=2. This is necessary due to how getblock returns
a block's transaction data based on the provided verbosity parameter.
If verbosity=1, then getblock.Tx is an array of a block's transaction ids (txids) as strings.
If verbosity=2, then getblock.Tx is an array of raw transaction data.
Due to differences in how getblock returns data based on the provided verbosity parameter, it's necessary
to have two separate return types based on verbosity. This necessitates a separate unmarshalling function
(represented throughout rpcclient/chain.go as Result.Receive()) to ensure that data is correctly unmarshalled
and returned to the user.
* rpcclient: replace futures mainnet with params
Adds a chaincfg.Params to the Client
rpcclient: parse config to assign params
* rpcclient: change address commands to Address
* Change address future struct to contain a network field, so futures
can return the correct type for Receive

Go 1.10 made some changes such that json.Unmarshal can no longer
unmarshal into exported fields that are themselves embedded via an
uninitialized unexported pointer.
Since rpcclient previously relied on this behavior, this updates the
client to create the pointers before unmarshalling into the struct.
