Title: Add "mempool" P2P command

This adds the "mempool" P2P command, which returns the first 50,000 entries in the TX memory pool (CInv vectors are capped at 50,000 already). SPV clients and other nodes may use this command following a block sync-up, to ensure they have the latest snapshot of the collective network.
