Accepting request 734169 from home:luke_nukem:branches:devel:languages:rust

- Add patch add-option-to-allow-warnings.patch to add a config option
  which allows warnings and so enables v1.38 to bootstrap itself.
- Update to version 1.38.0
  + Language
    - The `#[global_allocator]` attribute can now be used in submodules.
    - The `#[deprecated]` attribute can now be used on macros.
  + Compiler
    - Added pipelined compilation support to `rustc`. This will
      improve compilation times in some cases.
  + Libraries
    - `ascii::EscapeDefault` now implements `Clone` and `Display`.
    - Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
	  available at the same path as the trait. (e.g. The `Clone` derive macro
	  is available at `std::clone::Clone`). This also makes all built-in macros
	  available in `std`/`core` root. e.g. `std::include_bytes!`.
    - `str::Chars` now implements `Debug`.
    - `slice::{concat, connect, join}` now accepts `&[T]` in addition to `&T`.
    - `*const T` and `*mut T` now implement `marker::Unpin`.
    - `Arc<[T]>` and `Rc<[T]>` now implement `FromIterator<T>`.
    - Added euclidean remainder and division operations (`div_euclid`,
	  `rem_euclid`) to all numeric primitives. Additionally `checked`,
	  `overflowing`, and `wrapping` versions are available for all
	  integer primitives.
    - `thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`, and
      `PartialEq`.
    - `iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.
  + Stabilized APIs
    - `<*const T>::cast`
    - `<*mut T>::cast`
    - `Duration::as_secs_f32`
    - `Duration::as_secs_f64`
    - `Duration::div_f32`
    - `Duration::div_f64`
    - `Duration::from_secs_f32`
    - `Duration::from_secs_f64`
    - `Duration::mul_f32`
    - `Duration::mul_f64`
    - `any::type_name`
  + Cargo
    - Added pipelined compilation support to `cargo`.
    - You can now pass the `--features` option multiple times to enable
      multiple features.
  + Misc
    - `rustc` will now warn about some incorrect uses of
      `mem::{uninitialized, zeroed}` that are known to cause undefined behaviour.
