Subject: [PATCH 0/2] Remove `ArcBorrow`

From: Wedson Almeida Filho <walmeida@...rosoft.com>

In this small series we remove `ArcBorrow<'_, T>` and replace it with
`&WithRef<T>`, which we used to call `ArcInner` --  it is renamed
because it is now public, so we chose a more meaningful name.

This simplifies the code because we remove a type and have simpler
syntax to refer to borrowed arcs: `ArcBorrow<'a, T>` vs 
`&'a WithRef<T>`.

This became possible when we adopted GATs in 2021 but we only realised
it recently (thanks Boqun!), more details on this zulip thread:
https://rust-for-linux.zulipchat.com/#narrow/stream/291566-Library/topic/Isn't.20.60ArcBorrow.60.20just.20.60.26ArcInner.3CT.3E.60.3F

Wedson Almeida Filho (2):
  rust: arc: rename `ArcInner` to `WithRef`
  rust: arc: remove `ArcBorrow` in favour of `WithRef`
