tor-proto: new stream entries now take `StreamSendFlowControl`

2025-04-23T18:38:23Z

Previously new stream entries required a `StreamSendWindow`, but to support other flow control algorithms, we want new stream entries to take a `StreamSendFlowControl` instead. This also deduplicates the `StreamSendWindow` creation code.

tor-proto: Move Circuit to its own module.

2025-03-06T10:06:20Z

This is mostly code motion + some visibility adjustments. Moving all of these outside of `reactor` makes it easier to see which parts are internal vs which are accessed by the reactor. It also helps us enforce/audit invariants such as 'there should be no contention on the `CircHop::map` mutex' (the stream map is now private to `reactor::circuit`, and therefore nothing inside `reactor` will be directly accessing it).

tor-proto: Add a tunnel module.

2025-02-20T20:15:12Z

Move StreamTarget to the tunnel module and the circuit module. From now on streams will be implemented on tunnels, not circuits. This moves `StreamTarget` to the tunnel module. A future change will replace `ClientCirc` with `ClientTunnel` inside `StreamTarget`. This is mostly code motion, best reviewed with `--color-moved`. Signed-off-by: David Goulet
