Add a caret_int HandshakeType for HTYPE constants

Change `CircId` to never be zero

2023-10-25T20:35:12Z

This changes the internal representation to be `NonZeroU32` instead of just `u32`. Various places where a circuit ID is optional now use `Option`. Fixes a bug in `CircIdRange::sample` that would previously return a circuit ID of 0, when the rng returned 0x8000_0000 for a low range.

oneshot: Apply deferred rustfmt churn

cargo fmt, precisely.

tor-proto: Fix dead_code when building without experimental-api

proto: methods to wait until a channel/circuit is shut down.

2023-08-04T17:37:28Z

The implementation here is perhaps excessively simple: we put a `oneshot::Sender` in the `Reactor` object, and a `Shared` in the circuit or channel. When the reactor is dropped, any copy of the `Shared` will yield `Err(Cancelled)`. I'm marking these methods as experimental because I'm not sure I've thought of all the implications here, and we might want to change things around. Down the road, these methods might want to yield a `Result<>` indicating why the reactor was shut down. This feature was inspired by a request from Saksham Mittal, and a felt need while working on !1472.

proto: document channel lifecycle better.

Rename OpenClientChan{Msg,Cell} => OpenChan{Msg,Cell}S2C

tor-proto: Do not parse forbidden commands on inbound cells.

2023-02-09T15:20:31Z

Unlike C tor, we treat unrecognized commands as reason to kill off the connection entirely. That's fine; if we need to add an unrecognized command in the future, we can use VERSIONS to negotiate it. Also, if someday we want this code to support relay channels as well, we can use some type trickery to have that work too.

tor-proto: only parse allowed ChanMsg types during handshake.
