Add "TODO RPC" notes around DataStreamCtrl per review.

2023-05-24T19:25:33Z

proto: Add stream-status functionality to DataStreamCtrl.

2023-05-24T19:25:33Z

There are some weaknesses and problems here; see TODO notes.

proto: Create a `DataStreamCtrl` type.

2023-05-22T15:27:44Z

The idea here is that we want to make DataStream visible to the RPC system without requiring that the RPC session hold the DataStream itself (or the Reader, or the Writer). We could solve this problem by making _all_ the state in the DataStream shared, but that would introduce unnecessary extra locking in our critical path. Instead we're creating the notion of a "control handle" that lets you manage and observe a stream without actually owning the stream. Right now the only supported functionality is asking for the stream's circuit. Part of #847

Refactor ClientCirc APIs to use Arc.

2023-05-16T13:02:09Z

Now ClientCirc is no longer `Clone`, and the things that need it to be `Clone` instead return and use an Arc We're doing this so that ClientCirc can participate in the RPC system, and so that its semantics are more obvious. Closes #846. Thanks to the type system, this was a much simpler refactoring than I had feared it would be.

Add some missing imports

2023-03-28T14:49:45Z

Now nailing-cargo +stable clippy -p tor-hsclient --all-features --all-targets actually works. squash! Add some missing imports

Add an experimental circuit accessor to DataStream.

2023-03-23T13:18:42Z

Closes #784.

proto: Tweak documentation and names around CmdChecker.

2023-02-27T13:14:15Z

tor-proto: Introduce CmdChecker, and define it for our streams.

2023-02-17T16:50:27Z

The role of CmdChecker is to verify that messages are arriving at the appropriate sequence on a stream, with respect to the other messages that have been received. Once the stream becomes half-closed, the CmdChecker is also in charge of consuming incoming messages on the stream and making sure that they are well-formed.

tor-proto: note implications for future HS work

2023-02-15T15:48:19Z

tor-proto: Push stream message parsing into the stream objects.

2023-02-15T15:48:19Z

This closes #525, and ensures, at last, that we don't parse any message that we wouldn't accept.
