Update rust to version 1.34.0.

Pkgsrc changes:
 * Bump required rust version to build to 1.33.0.
 * Adapt patches to changed file locations.
 * (I worry about 32-bit ports, now that Atomic64 apparently is First-Class;
   this has been built on NetBSD/amd64 so far)

Upstream changes:

Version 1.34.0 (2019-04-11)
==========================

Language
--------
- [You can now use `#[deprecated = "reason"]`][58166] as a shorthand for
  `#[deprecated(note = "reason")]`. This was previously allowed by mistake
  but had no effect.
- [You can now accept token streams in `#[attr()]`,`#[attr[]]`, and
  `#[attr{}]` procedural macros.][57367]
- [You can now write `extern crate self as foo;`][57407] to import your
  crate's root into the extern prelude.


Compiler
--------
- [You can now target `riscv64imac-unknown-none-elf` and
  `riscv64gc-unknown-none-elf`.][58406]
- [You can now enable linker plugin LTO optimisations with
  `-C linker-plugin-lto`.][58057] This allows rustc to compile your Rust code
  into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI
  boundaries.
- [You can now target `powerpc64-unknown-freebsd`.][57809]


Libraries
---------
- [The trait bounds have been removed on some of `HashMap<K, V, S>`'s and
  `HashSet<T, S>`'s basic methods.][58370] Most notably you no longer require
  the `Hash` trait to create an iterator.
- [The `Ord` trait bounds have been removed on some of `BinaryHeap<T>`'s basic
  methods.][58421] Most notably you no longer require the `Ord` trait to create
  an iterator.
- [The methods `overflowing_neg` and `wrapping_neg` are now `const` functions
  for all numeric types.][58044]
- [Indexing a `str` is now generic over all types that
  implement `SliceIndex<str>`.][57604]
- [`str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and
  `str::trim_{start, end}_matches` are now `#[must_use]`][57106] and will
  produce a warning if their returning type is unused.
- [The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and
  `overflowing_pow` are now available for all numeric types.][57873] These are
  equivalvent to methods such as `wrapping_add` for the `pow` operation.


Stabilized APIs
---------------

#### std & core
* [`Any::type_id`]
* [`Error::type_id`]
* [`atomic::AtomicI16`]
* [`atomic::AtomicI32`]
* [`atomic::AtomicI64`]
* [`atomic::AtomicI8`]
* [`atomic::AtomicU16`]
* [`atomic::AtomicU32`]
* [`atomic::AtomicU64`]

* [`slice::sort_by_cached_key`]
* [`str::escape_debug`]
* [`str::escape_default`]
* [`str::escape_unicode`]
* [`str::split_ascii_whitespace`]

#### std
* [`Instant::checked_add`]
* [`Instant::checked_sub`]
* [`SystemTime::checked_add`]
* [`SystemTime::checked_sub`]

Cargo
-----
- [You can now use alternative registries to crates.io.][cargo/6654]

Misc
----
- [You can now use the `?` operator in your documentation tests without manually
  adding `fn main() -> Result<(), _> {}`.][56470]

Compatibility Notes
-------------------
- [`Command::before_exec` is now deprecated in favor of the
  unsafe method `Command::pre_exec`.][58059]
- [Use of `ATOMIC_{BOOL, ISIZE, USIZE}_INIT` is now deprecated.][57425] As you
  can now use `const` functions in `static` variables.
