This commit makes several related changes to the network code: - adds a `TransactionsByHash(HashSet<transaction::Hash>)` request and `Transactions(Vec<Arc<Transaction>>)` response pair that allows fetching transactions from a remote peer; - adds a `PushTransaction(Arc<Transaction>)` request that pushes an unsolicited transaction to a remote peer; - adds an `AdvertiseTransactions(HashSet<transaction::Hash>)` request that advertises transactions by hash to a remote peer; - adds an `AdvertiseBlock(block::Hash)` request that advertises a block by hash to a remote peer; Then, it modifies the connection state machine so that outbound requests to remote peers are handled properly: - `TransactionsByHash` generates a `getdata` message and collects the results, like the existing `BlocksByHash` request. - `PushTransaction` generates a `tx` message, and returns `Nil` immediately. - `AdvertiseTransactions` and `AdvertiseBlock` generate an `inv` message, and return `Nil` immediately. Next, it modifies the connection state machine so that messages from remote peers generate requests to the inbound service: - `getdata` messages generate `BlocksByHash` or `TransactionsByHash` requests, depending on the content of the message; - `tx` messages generate `PushTransaction` requests; - `inv` messages generate `AdvertiseBlock` or `AdvertiseTransactions` requests. Finally, it refactors the request routing logic for the peer set to handle advertisement messages, providing three routing methods: - `route_p2c`, which uses p2c as normal (default); - `route_inv`, which uses the inventory registry and falls back to p2c (used for `BlocksByHash` or `TransactionsByHash`); - `route_all`, which broadcasts a request to all ready peers (used for `AdvertiseBlock` and `AdvertiseTransactions`). |

Hello! I am Zebra, an ongoing Rust implementation of a Zcash node.
Zebra is a work in progress. It is developed as a collection of zebra-*
libraries implementing the different components of a Zcash node (networking,
chain structures, consensus rules, etc), and a zebrad binary which uses them.
Most of our work so far has gone into zebra-network, building a new
networking stack for Zcash, zebra-chain, building foundational data
structures, zebra-consensus, implementing consensus rules, and
zebra-state, providing chain state.
Rendered docs from the main branch.
