Mike Hearn 84f738763f Patch 11 from Steves lazy parsing patchset. 
Cache checksum for non-empty messages.

VersionMessage and AddressMessage require some special handling.  VersionMessage because it's never lazy parsed or cached.  AddressMessage because when serializing PeerAddresses the time field is dynamic.

Checksum byte array is currently transient so no gains for a message extracted from java serialization then bitcoinSerialized.  I don't think this would ever happen in real life but if it does then it could also be included in the serialized object.

README 

To get started, ensure you have the latest JDK installed, and download Maven from:

  http://maven.apache.org/

Then run "mvn clean package" to compile the software. You can also run "mvn site:site" to generate a website with
useful information like JavaDocs. The outputs are under the target/ directory.

Now ensure you're running a BitCoin node locally and run the example app:

  mvn exec:java -Dexec.mainClass=com.google.bitcoin.examples.PingService

It will download the block chain and eventually print a BitCoin address. If you send coins to it,
you should get them back a few minutes later when a block is solved.

Note that if you connect to a node that is itself downloading the block chain, you will see very slow progress (1
block per second or less). Find a node that isn't heavily loaded to connect to.

If you get a SocketDisconnectedException, the node you've connected to has its max send buffer set to low
(unfortunately the default is too low). Connect to a node that has a bigger send buffer,
settable by passing -maxsendbuffer=25600 to the Bitcoin C++ software.

For the convenience of Eclipse users, you can copy dependency jars to target/dependency using:

    mvn dependency:copy-dependencies
