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.)

Move fallback.rs into guardmgr.

This is the logical place for it, I think: the GuardMgr's job is to pick the first hop for a circuit depending on remembered status for possible first hops. Making this change will let us streamline the code that interacts with these objects.

Merge branch 'disallowed_lint' into 'main'

Remove allow(clippy::disallowed_methods) lint flag. See merge request tpo/core/arti!437

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.

Remove allow(clippy::disallowed_methods) lint.

Use less space in hashtables for microdescriptors Closes #386 See merge request tpo/core/arti!415

derive_builder: Switch to upstream 0.11

2022-03-16T16:34:44Z

This has the different syntax for builder field attributes than what I originally proposed in my MR, and which therefore is in the pinned branch. My upstream MR for the field attributes feature was morged: https://github.com/colin-kiegel/rust-derive-builder/issues/239

netdir: Use an even smaller rep for list of microdescs

2022-03-16T15:52:47Z

Every time we want a microdescriptor, we know the index of that microdesc's corresponding routerstatus within the consensus. Therefore, we can use that index to store `Arc`s in a dense array, and not have to use a HashSet here at all.

tor-dirmgr: Remove redundant hashtable.

2022-03-16T15:33:19Z

We were using a hashtable to keep track of missing microdescriptor digests. But this information is redundant with the NetDir state, and there's now no longer any performance benefit to keeping a separate copy. Part of #386.
