The getwork command alters the output depending on whether or not the
optional data parameter was specified. It is a JSON object when no data
was provided, and a boolean indicating whether a solution was found
when data was provided.
The getwork RPC now only accepts a single optional parameter which, if
present, is a string containing the hex-encoded block data to solve.
Also update the tests for the new correct parameters.

The getaddednode command dns flag alters the output. It is a JSON object
when true and a slice of strings containing the addresses when false.
Note there is a bug in bitcoind as of version 0.8.6 which returns the
addresses as a JSON object with duplicate keys. This has been reported as
issue 3581 on the bitcoind issue tracker.
This commit allows the result for getaddednodeinfo to be either the JSON
object or the string slice.
The inputs to the createrawtransaction command are JSON strings, however
the NewCreateRawTransactionCmd function takes concrete types. Thus,
callers which deal with the raw JSON need a method to perform the
validation and conversion. This logic is the same as what needs to happen
when unmashalling a full JSON-RPC command, so this commit factors that
logic out into a separate function and exports it.
Added MarshalJSON method to Vin which properly omits the Vout field
from coinbase Vin's by using anonymous structs with the proper
subsets of fields outputted by bitcoind
Changed Vout.ScriptPubKey to add omitempty for ReqSigs and Addresses:
both fields are not shown when there is an error identifying to
scriptType or parsing addresses in bitcoind
The previous commit modified the Vin ScriptSig field to be a pointer to an
anonymous struct so it could be properly omitted. However, the callers
need to be able to create a new object to assign to the field, so this
commit makes the previous anonymous struct an exported type named
ScriptSig.
In order for a field which is a struct to be omitted from JSON
marshal/unmarshal, it must be a pointer so the json package can tell when
it's empty (when it's nil).
