This commit adds support for a BrokenTcp provider that can make
connection attempts fail or time out. It doesn't yet have a way to
turn on the failure.

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<Error>` instead.
Found while heap profiling.
Closes #383.

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

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 ยง 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)

Previously we tried to do each connection in a run, and only then did we
start transferring data over them. Now we collect a bunch of the
futures that return an open stream, and run them all in parallel
with using them. This change includes connect-time in our
benchmarks, and allows us to test contention in our connect code.
Instead of using a Stream, I've changed the connection-generation
code to call a future-returning function directly, so we have a way
to explicitly pass which run we're in.

The doc include rune does not work with our MSRV; it needs 1.54.
The alternative would be some kind of cfg() but that would
- not provide the crate-level doc on Rust 1.53
- involve the use of cfg_attr
Instead, just do it the old way.

This commit changes the main parsing code for RsaIdentity in
tor-netdoc, and .
Previously, parse_hex_ident was something like 10% of our startup
CPU time; now it's only like ~2%. (Still not perfect, but way
better.)
Closes #377.

We perform this operation in a bunch of places, and most of them
use hex::decode(). That's not great, since hex::decode() has to do
heap allocation. This implementation uses hex::decode_to_slice(),
which should be faster.
(In the future we might choose to use one of the faster hex
implementations, but I'm hoping that this change will be sufficient
to get hex decoding out of our profiles.)
Part of #377.
