Make a network node's transaction memory pool accessible via a new “mempool” message. Extend the existing “getdata” message behavior to permit accessing the transaction memory pool.

Several use cases make it desirable to expose a network node's transaction memory pool:

1. Simple Payment Verification (SPV) clients, wishing to obtain zero-confirmation transactions sent or received.

2. Miners, to avoid missing lucrative fees, downloading existing network transactions after a restart.

3. Remote network diagnostics.
