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.

Access to connections map and associated notification maps in rpcServer
need to be protected with s.ws.Lock to prevent race with add/remove new
clients.
This closes#88.
This commit resolves an issue where the block node index was forcing
entire blocks to be kept in memory thereby forcing excessive memory usage.
For example, prior to this change, the memory usage could consume upwards
of 1.5GB while importing bootstrap.dat via the addblock utility. With
this change the entire import takes <150MB. This also has the same memory
reduction to btcd since it uses the same code path.
Changed mempool.MaybeAcceptTransaction to accept an additional parameter
to differentiate betwee new transactions and those added from
disconnected blocks.
Added new fields to requestContexts to indicate which clients want to
receive all new transaction notifications.
Added NotifyForNewTx to rpcServer to deliver approriate transaction
notification.
Sending NotifyAllNewTXsCmd will register websocket client to receive
notifications on all new transactions.
Once registered the client will receive either AllTxNtfn or
AllVerboseTxNtfn based on the required verbose field in the
NotifyAllNewTXsCmd.
Previously the getnettotals was just looping through all of the currently
connected peers to sum the byte counts and returning that. However, the
intention of the getnettotals RPC is to get all bytes since the server was
started, so this logic was not correct.
This commit modifies the code to keep an atomic counter on the server for
bytes read/written and has each peer update the server counters as well as
the per-peer counters.
