Bump all arti, tor crates to 0.2.0

2022-04-01T13:15:18Z

Not all of these strictly need to be bumped to 0.2.0; many could go to 0.1.1 instead. But since everything at the tor-rtcompat and higher layers has had breaking API changes, it seems not so useful to distinguish. (It seems unlikely that anybody at this stage is depending on e.g. tor-protover but not arti-client.)

Make daemon tasks self-contained; introduce NetDirProvider

2022-03-30T13:26:43Z

The various background daemon tasks that `arti-client` used to spawn are now handled inside their respective crates instead, with functions provided to spawn them that return `TaskHandle`s. This required introducing a new trait, `NetDirProvider`, which steals some functionality from the `DirProvider` trait to enable `tor-circmgr` to depend on it (`tor-circmgr` is a dependency of `tor-dirmgr`, so it can't depend on `DirProvider` directly). While we're at it, we also make some of the tasks wait for events from the `NetDirProvider` instead of sleeping, slightly increasing efficiency.

tor-proto: add a backend to detect reported clock skew.

2022-03-23T12:24:36Z

NETINFO cells, which are sent in every handshake, may contain timestamps. This patch adds an accessor for the timestamp in the Netinfo messages, and teaches the tor-proto code how to compute the minimum clock skew in the code. The computation isn't terribly precise, but it doesn't need to be: Tor should work fine if your clock is accurate to within a few hours. This patch also notes a Y2038 problem in the protocol: see torspec#80. Part of #405.

tor-chanmgr: Do not allocate an Internal error unless we mean it.

Previously we'd allocate an error as a place-holder here, but it's not a great idea to do that with a `Bug`: each `Bug` stores a whole stack trace, which uses a whole pile of allocations to construct. Now we keep an `Option` instead. Found while heap profiling. Closes #383.

Implement a basic form of RFC 8305 ("happy eyeballs") for channels

2022-03-07T14:56:51Z

This makes Arti usable in IPv6-only environments (arti#92) by letting us attempt multiple connections to a given relay using all of its addresses instead of just using the first (probably IPv4) one, using the strategy from RFC 8305 § 5. This isn't a complete implementation of Happy Eyeballs; ideally, we'd sort the address list before doing concurrent connections. However, it works (and has been tested inside an IPv6-only container inside eta's network :p)
