[PATCH 0/4] rust: pin-init: support tuple structs

[Gary Guo <gary@garyguo.net>]

This is a long requested feature to support tuple structs. There are a few
cases that structs have to be converted to become normal structs so
pin-init can be used.

This series add tuple struct support as you'd expect to work. A caveat is
that pinned initialization syntax (`<-`) only works with struct expression
initializers. So

    #[pin_data]
    struct Foo<T>(#[pin] T, usize)

would need

    pin_init!(Foo {
        0 <- expr,
        1: 0
    })

This is to avoid introducing new syntax.
