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: Move most of the reactor impl to Circuit.

This is an intermediate step in rewriting the reactor to manage a "conflux set" (a set of linked circuits) rather than a single circuit. This commit contains no functional changes.

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
