This switches out `arti`'s argument-parsing library with `clap`, which
is a lot more featureful (and very widely used within the Rust
ecosystem). We also now use a lot of `clap`'s features to improve the
CLI experience:
- The CLI now expects a subcommand (currently, either "help", or "proxy"
for the existing SOCKS proxy behaviour). This should let us add
additional non-SOCKS-proxy features to arti in future.
- `clap` supports default values determined at runtime, so the way the
default config file is loaded was changed: now, we determine the
OS-specific path for said file before invoking `clap`, so the help
command can show it properly.
- The behaviour of `tor_config` was also changed; now, one simply
specifies a list of configuration files to load, together with
whether they're required.
- That function also way overused generics; this has been fixed.
- Instead of using the ARTI_LOG environment variable to configure
logging, one now uses the `-l, --log-level` CLI option.
(The intent is for this option to be more discoverable by users.)
- The `proxy` subcommand allows the user to override the SOCKS port used
on the CLI without editing the config file.
The affected API (getgrouplist) isn't one that we use, directly or
transitively. We can't just upgrade immediately, since the ctrlc
crate is currently stuck on the older version of nix.
Previously I'd hoped to have it only apply to reproducible builds,
but the work of keeping it up-to-date and checking it for drift
seems to have been tripping us up. Let's try doing it the other way
for now, and we'll see how that goes.
Currently adding new deps can cause builds to not be reproducibles
because that new dependancies don't have their versions frozen in
misc/Cargo.lock.
This make so CI reject commits in that situation, with a message telling
what to do to fix the issue.

The "--all" flag is deprecated in favor of "--workspace", which
isn't actually needed here.
"--all-features" catches a few things that we want to make sure
we're catching.
Let's try out cargo doc and make sure that passes too.
