In `workspace`:
- New dependencies: `arti_client`, `Cuprate/tokio-socks.git`, `tor-cell`, `tor-config-path`, `tor-hsservice`, `tor-persist`, `tor-proto`, `tor-rtcompat` (yes nothing was exported).
- In `deny.toml`, whitelisted `Unlicense` license for `arti_client`.
In `cuprate-p2p-transport`:
- Implemented `Transport<ClearNet>` and `Transport<Tor>` for `Arti`. New `ArtiClientConfig`, `ArtiServerConfig` configuration. New `OnionListener` for accepting inbound connections from arti's generated onion service.
- Implemented `Transport<Tor>` for `Daemon`. New `DaemonClientConfig`, `DaemonServerConfig` configuration. New `DaemonInboundStream` listening for incoming TCP connections from the tor daemon.
- `DisabledListener` as a polyfill for transports with inbound disabled, such as `Transport<ClearNet> for Arti` and in the future `Transport<ClearNet> for Socks5`.
In `cuprate-p2p-core`:
- Removed `Default` and `Debug` bound from `Transport::ClientConfig` and `Transport::ServerConfig`.
- Removed `Clone` bound from `Transport::ServerConfig`.
In `cuprate-p2p`:
- Changed some function visibility to `pub(super)` instead of `pub`.
In `cuprate-wire`:
- Added `borsh` dependency and `BorshSerialize` and `BorshDeserialize` derived implementation to `OnionAddr` for `BorshNetworkZone` requirement in address book.
In `cuprated`:
- New `tor` module containing the initialization of Arti, config helpers and context structure `TorContext` to pass down to p2p initialization function and other helpers.
- New `config/tor` module containing the `[tor]` configuration table. It define tor daemon related variables, as well as arti settings.
- Added `enable_inbound` field to `ClearNetConfig` to disable incoming listener by default.
- Added `proxy` field to `ClearNetConfig` for enabling clearnet over arti and in the future proxy urls.
- Added `TorNetConfig` for setting `Tor` network zone parameters such as listening ports, enabling arti inbound server, or setting an anonymous inbound onion address from an external daemon.
- Modified `initialize_zones_p2p` to now start Tor network zone and use the correct transport depending on user configuration.
- In `txpool/*`, generalized `DiffuseService`, `OutboundPeerStream` and `ConcreteDandelionRouter` for `Z: NetworkZone`. Created a new `MainDandelionRouter` service that will route local txs to a Tor router instead of clearnet if available. Adapted initialization to the changes.
