[Bitcoin-development] Protocol changes for SPV clients: mempool, getdata commands

[Jeff Garzik]

A small change to the protocol is proposed for satoshi client v0.7
(upcoming release):

    Add 'mempool' P2P command, and extend 'getdata' behavior
    https://github.com/bitcoin/bitcoin/pull/1641

The genesis of this command is to permit SPV clients to access the
memory pool, but secondary uses include diagnostics and miner download
(so that miners won't miss lucrative TX's due to node restart).
"getdata" behavior is extended to include any memory pool transaction,
relaxing a previous "getdata" restriction.

Didn't feel this warranted a BIP, but can write one if people really want one.

Fully agree with the changes, but I think there should be a small BIP, for
consistency, and to make it documented for other client developers.
