In the `module!` macro, the `author` field is currently of type `String`.
Since modules can have multiple authors, this limitation prevents
specifying more than one.
Add an `authors` field as `Option<Vec<String>>` to allow creating
modules with multiple authors, and change the documentation and all
current users to use it. Eventually, the single `author` field may
be removed.
[ The `modinfo` key needs to still be `author`; otherwise, tooling
may not work properly, e.g.:
$ modinfo --author samples/rust/rust_print.ko
Rust for Linux Contributors
I have also kept the original `author` field (undocumented), so
that we can drop it more easily in a kernel cycle or two.

Now that we got the kernel `Vec` in place, convert all existing `Vec`
users to make use of it.

We also rename the methods by removing the `try_` prefix since the names
are available due to our usage of the `no_global_oom_handling` config
when building the `alloc` crate.

Instead of taking binary string literals, take string ones instead,
making it easier for users to define a module, i.e. instead of
calling `module!` like:
module! {
...
name: b"rust_minimal",
...
}
now it is called as:
module! {
...
name: "rust_minimal",
...
}
Module names, aliases and license strings are restricted to
ASCII only. However, the author and the description allows UTF-8.
For simplicity (avoid parsing), escape sequences and raw string
literals are not yet handled.

The beginning of a set of Rust modules that showcase how Rust
modules look like and how to use the abstracted kernel features.
It also includes an example of a Rust host program with
several modules.
These samples also double as tests in the CI.
