Update rust to version 1.36.0

Pkgsrc changes:
 * NetBSD/sparc64 disabling of "packed" removed ("packed" removed upstream)
 * Adapt src_libstd_build.rs patch, update sed'ing of .cargo-checksum.json

Build verified on NetBSD 8.0/amd64.

Upstream changes:

Version 1.36.0 (2019-07-04)
==========================

Language
--------
- [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114]
- [The order of traits in trait objects no longer affects the semantics of that
  object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to
  `dyn fmt::Debug + Send`, where this was previously not the case.

Libraries
---------
- [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implem
entation.][58623]
- [`TryFromSliceError` now implements `From<Infallible>`.][60318]
- [`mem::needs_drop` is now available as a const fn.][60364]
- [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][6
0370]
- [`String` now implements `BorrowMut<str>`.][60404]
- [`io::Cursor` now implements `Default`.][60234]
- [Both `NonNull::{dangling, cast}` are now const fns.][60244]
- [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset
  of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the
  environment has access to heap memory allocation.
- [`String` now implements `From<&String>`.][59825]
- [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will
  return a tuple of each argument when there is multiple arguments.
- [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if
  not used.][59648]

Stabilized APIs
---------------
- [`VecDeque::rotate_left`]
- [`VecDeque::rotate_right`]
- [`Iterator::copied`]
- [`io::IoSlice`]
- [`io::IoSliceMut`]
- [`Read::read_vectored`]
- [`Write::write_vectored`]
- [`str::as_mut_ptr`]
- [`mem::MaybeUninit`]
- [`pointer::align_offset`]
- [`future::Future`]
- [`task::Context`]
- [`task::RawWaker`]
- [`task::RawWakerVTable`]
- [`task::Waker`]
- [`task::Poll`]

Cargo
-----
- [Cargo will now produce an error if you attempt to use the name of a required
dependency as a feature.][cargo/6860]
- [You can now pass the `--offline` flag to run cargo without accessing the netw
ork.][cargo/6934]

You can find further change's in [Cargo's 1.36.0 release notes][cargo-1-36-0].

Clippy
------
There have been numerous additions and fixes to clippy, see [Clippy's 1.36.0 rel
ease notes][clippy-1-36-0] for more details.

Misc
----

Compatibility Notes
-------------------
- [`std::arch::x86::_rdtsc` returns `u64` instead of `i64`][stdsimd/559]
- [`std::arch::x86_64::_mm_shuffle_ps` takes an `i32` instead of `u32` for `mask
`][stdsimd/522]
- With the stabilisation of `mem::MaybeUninit`, `mem::uninitialized` use is no
  longer recommended, and will be deprecated in 1.38.0.
