Miguel Ojeda e8fa0481ea pin-init changes for v6.17
Added:
 
 - 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are now
   (pin-)initializers.
 
 - 'Zeroable::init_zeroed()' delegating to 'init_zeroed()'.
 
 - New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
   it via 'Zeroable::zeroed()'.
 
 - Implement 'Zeroable' for 'Option<&T>' and 'Option<&mut T>'.
 
 - Implement 'Zeroable' for 'Option<[unsafe] [extern "abi"]
   fn(...args...) -> ret>' for '"Rust"' and '"C"' ABIs and up to 20
   arguments.
 
 Changed:
 
 - Blanket impls of 'Init' and 'PinInit' from 'impl<T, E> [Pin]Init<T, E>
   for T' to 'impl<T> [Pin]Init<T> for T'.
 
 - Renamed 'zeroed()' to 'init_zeroed()'.
 
 Upstream dev news:
 
 - More CI improvements to deny warnings, use '--all-targets'. Also check
   the synchronization status of the two '-next' branches in upstream and
   the kernel.
