*Added in protocol version 70209 of Dash Core as described by BIP152*
The `cmpctblock` message transmits a single serialized compact block. A
`HeaderAndShortIDs` structure is used to relay a block header, the short
transactions IDs used for matching already-available transactions, and a select
few transactions which we expect a peer may be missing (PrefilledTransactions).
It can be sent for two different reasons:
1. **GetData Response:** Nodes will always send it in response to a
`getdata` message that requests the block with an inventory
type of `MSG_CMPCT_BLOCK` (provided the node has that block available for
relay).
2. **Unsolicited:** If a node has previously sent a `sendcmpct` message
requesting blocks be announced via a `cmpctblock` message.

The `sendcmpct` message tells the receiving peer whether or not to announce new
blocks using a `cmpctblock` message. It also sends the compact block protocol
version it supports.
