Removed unnecessary lint

This commit executes maint/add_warning with the just added change to
deny string slices except in tests.
I recommend auditing this by checking out the previous commit followed
by running the script yourself and then verifying that the diff is
identical to this commit.
This commit makes cargo clippy fail. We will add exceptions in the next
commit.

`clippy::collapsible_if` started triggering after bumping the MSRV to
1.88.
Since this triggers from a lot of places, and since there even are a
couple of instances where we explicitly allow `clippy::collapsible_ifs`,
I've opened #2342 for deciding what to do about it.

This adds the lint to all our crates.

In 1.83, this warning triggers on many of our crates.
We're thinking of fixing them all, but for now,
we're going to disable the warning.
This is part of #1765.

This warning kind of snuck up on us! (See #748) For now, let's
disable it. (I've cleaned it up in a couple of examples, since
those are meant to be more idiomatic and user-facing.)
Closes #748.

The remaining consequences of running add_warning

From running add_warning, with manual picking of the right
hunks/lines.

This was the result of:
maint/add_warning crates/*/src/{lib,main}.rs
and then manually curating the results.

|
|

This is just code motion and the minimal fixups.

This lint is IMO inherently ill-conceived.
I have looked for the reasons why this might be thought to be a good
idea and there were basically two (and they are sort of contradictory):
I. "Calling ‘.clone()` on an Rc, Arc, or Weak can obscure the fact
that only the pointer is being cloned, not the underlying data."
This is the wording from
https://rust-lang.github.io/rust-clippy/v0.0.212/#clone_on_ref_ptr
It is a bit terse; we are left to infer why it is a bad idea to
obscure this fact. It seems to me that if it is bad to obscure some
fact, that must be because the fact is a hazard. But why would it be
a hazard to not copy the underlying data ?
In other languages, faliing to copy the underlying data is a serious
correctness hazard. There is a whose class of bugs where things were
not copied, and then mutated and/or reused in multiple places in ways
that were not what the programmer intended. In my experience, this is
a very common bug when writing Python and Javascript. I'm told it's
common in golang too.
But in Rust this bug is much much harder to write. The data inside an
Arc is immutable. To have this bug you'd have use interior mutability
- ie mess around with Mutex or RefCell. That provides a good barrier
to these kind of accidents.
II. "The reason for writing Rc::clone and Arc::clone [is] to make it
clear that only the pointer is being cloned, as opposed to the
underlying data. The former is always fast, while the latter can
be very expensive depending on what is being cloned."
This is the reasoning found here
https://github.com/rust-lang/rust-clippy/issues/2048
This is saying that *not* using Arc::clone is hazardous.
Specifically, that a deep clone is a performance hazard.
But for this argument, the lint is precisely backwards. It's linting
the "good" case and asking for it to be written in a more explicit
way; while the supposedly bad case can be written conveniently.
Also, many objects (in our codebase, and in all the libraries we use)
that are Clone are in fact simply handles. They contain Arc(s) (or
similar) and are cheap to clone. Indeed, that is the usual case.
It does not make sense to distinguish in the syntax we use to clone
such a handle, whether the handle is a transparent Arc, or an opaque
struct containing one or more other handles.
Forcing Arc::clone to be written as such makes for code churn when a
type is changed from Arc<Something> to Something: Clone, or vice
versa.

Fixed conflict in crates/arti-client/src/lib.rs as per tree

Otherwise, it's impossible to get a static sqlite linkage without
also getting native-tls, even if you wanted rustls.

This makes using the `PreferredRuntime` the first-class option inside
`arti-client`, freeing users who don't want to think about runtimes from
having to do so.
`TorClient::create_unbootstrapped` and `builder` now automatically
use this runtime, leaving only `builder_custom` for users who wish to
manually specify a runtime.
This lets us clean up the docs a lot: mentions of using custom runtimes
are now relegated to nearer the end of the crate-level documentation,
and we mostly just link to `tor_rtcompat`'s docs to explain more there.
Instead, we take some more time to explain how you use the builder API
to create clients synchronously.
Other doc cleanups included getting rid of the explanation of `TorAddr`
in the main crate-level doc; this is already well-documented elsewhere,
and is something users should discover organically later.

This change is possible now that #293 is done.
As an immediate benefit, it allows us to start monitoring the
configuration files immediately, and not only after we're done
bootstrapping the client.

This commit changes how the `TorClient` type works, enabling it to be
constructed synchronously without initiating the bootstrapping process.
Daemon tasks are still started on construction (although some of them
won't do anything if the client isn't bootstrapped).
The old bootstrap() methods are now reimplemented in terms of the new
create_unbootstrapped() and bootstrap_existing() methods.
This required refactoring how the `DirMgr` works to enable the same sort
of thing there.

We don't yet do much with these, but we can avoid discarding them.

I'm slightly concerned about whether this is behavior people would
expect to have on-by-default, so let's make this off-by-default for
now.
Maybe the `application` and `system` sections should merge?

TorClient doesn't need to be wrapped in an Arc any longer, thanks
to other refactoring.

This is by no means our final API, but should represent an
improvement. Here instead of having to specify a list of files and
their is-this-optional status, along with a list of command-line
options, we have a single structure that encapsulates all of that
information.
Two advantages here:
- Callers no longer have to remember what the boolean means.
- We can "reload" more easily, by keeping the source object around.
This change also implements the correct behavior for our default
configuration file in `arti::main`: if the file is absent and the
user doesn't list a config file, that's no problem. But if the user
lists _that very same config file, we should insist that it be
present.
