clap can parse a PathBuf directly from the command line arguments, and
paths are not always UTF-8. Use PathBuf instead of a String to allow for
all valid filesystem paths.

Since everyone copied the first bits of code from the I2C crate, the
same issue is present almost everywhere. The returned value isn't
checked at all by the callers. Stop returning bool unnecessarily.

The error from joining a thread is a bit confusing. It is only printed
if the other thread panicked. This means, effectively, we only get here
if something called .unwrap(), .expect() or panicked in a different way.
In these cases an (ugly) error was already printend. Printing a pretty
message about the join failure does not really help a lot...
So let's just continue the unwind as suggested by the docs on the join
`Result` [1].
Before:
thread '<unnamed>' panicked at 'Test panic', crates/gpio/src/backend.rs:146:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Any { .. }', crates/gpio/src/backend.rs:176:23
After:
thread '<unnamed>' panicked at 'Test panic', crates/gpio/src/backend.rs:146:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This become available with the recent vhost-user-backend [1] updates and
allows to get rid of some boilerplate code.

- Features were renamed from slave -> backend
- Generics got simplified
- Some write and read functions on Volatile slice got turned into
standalone traits: ReadVolatile, WriteVolatile
- handle_event no longer returns a bool

Having all the workspace crates under the crates/ directory is
unnecessary. Rust documentation itself recommends all crates to be in
the root directory:
https://doc.rust-lang.org/book/ch14-03-cargo-workspaces.html#creating-the-second-package-in-the-workspace
I paste the text content here, in case the online page ever changes or
becomes unavailable:
## Creating the Second Package in the Workspace
Next, let’s create another member package in the workspace and call it add_one. Change the top-level Cargo.toml to specify the add_one path in the members list:
Filename: Cargo.toml
[workspace]
members = [
"adder",
"add_one",
]
Then generate a new library crate named add_one:
$ cargo new add_one --lib
Created library `add_one` package
Your add directory should now have these directories and files:
├── Cargo.lock
├── Cargo.toml
├── add_one
│ ├── Cargo.toml
│ └── src
│ └── lib.rs
├── adder
│ ├── Cargo.toml
│ └── src
│ └── main.rs
└── target
