…o that a wrapper client (such as a future TSIG client) can augment the message before it gets sent.

- Added a simple UDP client that doesn't interfere with requests before sending (for TSIG testing).
- Added support for receiving multiple responses (for XFR testing).
- Added support for connection timeout errors
- Added support for connection termination errors (for EDNS testing).
- Added support for specifying the TSIG key to use (for TSIG testing).
- Added support for $ORIGIN in zone file fragments.
- Simplified rcode checking and use it instead of the yxrrset BADCOOKIE hack.
- In memory channel changes:
  - Fixed a trace message that incorrectly referred to client instead of server.
  - Fixed a too-tight connection read loop that was preventing Tokio task switching.
  - Added connection shutdown detection.
- Fixed incorrect setting of TCP mode to true when UDP mode was requested.

- Add TSIG Stelline test recipe.
- Update Stelline server integration tests to use the new TSIG middleware.
- Remove unnecessary Unpin bounds in net::server::message::Request.
- Tsig module changes:
  - Derive Clone for Key.
  - Added Key::compose_len() for determining how many response bytes to reserve.
  - Added From<ServerTransaction<K>> for ServerSequence<K>.
  - Altered KeyStore blanket impls to avoid conflict with additional impl on Arc<KeyStore>.
  - Various minor RustDoc improvements.
  - Made tsig::ServerError::unsigned() public.
