warning: passing a unit value to a function
... and remove this warning from the "To be resolved" list in
bin/clippy.

bin/clippy and bin/fmt were missing license blurbs at the top,

This manifested itself in a couple places that were turning shared
memory buffers into slices for the purposes of passing these slices to
`Read` and `Write` trait methods.
However, this required the removal of the methods that took `Read` and
`Write` instances. This was a convenient interface but impossible to
implement safely because making slices from raw pointers without
enforcing safety guarantees causes undefined behaviour in Rust. It turns
out lots of code in crosvm was using these interfaces indirectly, which
explains why this CL touches so much.

This CL fixes four cases of what I believe are undefined behavior:
- In vhost where the original code allocates a Vec<u8> with 1-byte
alignment and casts the Vec's data pointer to a &mut vhost_memory
which is required to be 8-byte aligned. Underaligned references of
type &T or &mut T are always undefined behavior in Rust.
- Same pattern in x86_64.
- Same pattern in plugin::vcpu.
- Code in crosvm_plugin that dereferences a potentially underaligned
pointer. This is always undefined behavior in Rust.

Suppressing the lint locally because by the author's and reviewers'
judgement this was the clearest way to write this code. The lint is
still valuable for catching mistakes in copied and pasted code
elsewhere.

The script suppresses all currently failing lints. I broke this down
into lints that I believe are worth addressing and lints that I wouldn't
mind keeping suppressed indefinitely.

Add a script to run `cargo fmt` on all Rust code contained in crosvm.
This is different from `cargo fmt --all` which formats multiple crates
but a single workspace only. Crosvm consists of multiple workspaces.
Usage:
$ bin/fmt
To print a diff and exit 1 if code is not formatted, but without
changing any files, use:
$ bin/fmt --check
