Simplification: Every relay is in the same family as itself.

Make sure that a circuit doesn't use relays in the same family
...
We implement `Relay::in_same_family` which is in turn used by
`ExitPathBuilder::pick_path` to avoid picking relays in the
same family.
Compared to the original C implementation, we are missing
support for options EnforceDistinctSubnets and NodeFamilySets.
This has only been very lightly tested so far.

Remember the actual usable ports for an exit after we've built a circuit
...
Previously we'd just remember the port that we _wanted_ a circuit
for, and forget all the ports that it _could_ support.
This is part of a bigger circmgr revision/refactoring pass; there
should be cleanups before I merge this.

Refactor NetDir a little for space savings and updating
...
Rather than having the NetDir own its microdescs and consensus, give
it Arc<>s for them. This way, we can do a shallow copy of a NetDir
to work around mutability issues that would otherwise make it hard
to add microdescs to a netdir on the fly.

Checkpoint work on a sqlite backend.

Among other stuff, revert parts of previous commit that introduced a
ReadableStore abstraction: there isn't a good abstraction hat covers
both Tor legacy stores and sqlite stores-- or if there is, I'll have
to find it organizally.
This isn't a final version: it probably has bugs, and it needs
documentation and more tests. But before I do those, I want to
sanity-check the API by drafting the next layer up on the stack.

Improvements to Relay type in tor-netdir.
...
Now, a Relay is always valid. This required some changes to the
API: all_relays() has to return a new UncheckedRelay type that might
or might not be valid, and the functions on Relay and ChanTarget
that return ed25519 identities need to return an Ed25519Identity,
not an ed25519::PublicKey.
This change required some new encoding/decoding/conversion functions
on Ed25519Identity.

since we're now requiring that.
