[PATCH perlmod 0/4] perlmod: add #[hash] parameter

["Max R. Carrara" <m.carrara@proxmox.com>]

perlmod: add #[hash] parameter - v1
===================================

This series implements a `#[hash]` parameter similar to the existing
`#[list]` one, allowing us to create APIs like
`foo("arg", key => "value")` directly from Rust.

In other words, this essentially mirrors how a sub with `%params` as its
last parameter would work.

For example, this is one of the functions called by the tests that are
added in this series:

    #[export]
    fn trailing_hash(first: u32, #[hash] rest: HashMap<u32, u32>) -> String {
        format!("first={first}, rest is {rest:?}")
    }

This can then be called e.g. like this:

    let $res = TestLib::Hello::trailing_hash(42, 1337 => 123);
