Update rust to version 1.38.0.

Pkgsrc changes:
 * Adapt to the move of the implementation of random numbers.
 * Remove patch which is no longer relevant (Signals.inc)
 * Cross-build currently fails due to the still unresolved
   rust-lang/rust#62558, so bootstrap
   kits for 1.38.0 have to be built natively, and will follow shortly.
 * Bump bootstrap requirements to 1.37.0 except for armv7-unknown-netbsd-eabihf
   which I've neither managed to cross-build nor build natively.

Upstream changes:

Version 1.38.0 (2019-09-26)
==========================

Language
--------
- [The `#[global_allocator]` attribute can now be used in submodules.][62735]
- [The `#[deprecated]` attribute can now be used on macros.][62042]

Compiler
--------
- [Added pipelined compilation support to `rustc`.][62766] This will
  improve compilation times in some cases. For further information please refer
  to the [_"Evaluating pipelined rustc compilation"_][pipeline-internals]
  thread.
- [Added tier 3\* support for the `aarch64-uwp-windows-msvc`,
  `i686-uwp-windows-gnu`, `i686-uwp-windows-msvc`, `x86_64-uwp-windows-gnu`,
  and `x86_64-uwp-windows-msvc` targets.][60260]
- [Added tier 3 support for the `armv7-unknown-linux-gnueabi` and
  `armv7-unknown-linux-musleabi` targets.][63107]
- [Added tier 3 support for the `hexagon-unknown-linux-musl` target.][62814]
- [Added tier 3 support for the `riscv32i-unknown-none-elf` target.][62784]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

Libraries
---------
- [`ascii::EscapeDefault` now implements `Clone` and `Display`.][63421]
- [Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
  available at the same path as the trait.][63056] (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`.][63000]
- [`slice::{concat, connect, join}` now accepts `&[T]` in addition to
   `&T`.][62528]
- [`*const T` and `*mut T` now implement `marker::Unpin`.][62583]
- [`Arc<[T]>` and `Rc<[T]>` now implement `FromIterator<T>`.][61953]
- [Added euclidean remainder and division operations (`div_euclid`,
  `rem_euclid`) to all numeric primitives.][61884] Additionally `checked`,
  `overflowing`, and `wrapping` versions are available for all
  integer primitives.
- [`thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`, and
  `PartialEq`.][61491]
- [`iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.][61457]

Stabilized APIs
---------------
- [`<*const T>::cast`]
- [`<*mut T>::cast`]
- [`Duration::as_secs_f32`]
- [`Duration::as_secs_f64`]
- [`Duration::div_duration_f32`]
- [`Duration::div_duration_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`.][cargo/7143]
- [You can now pass the `--features` option multiple times to enable
  multiple features.][cargo/7084]

Misc
----
- [`rustc` will now warn about some incorrect uses of
  `mem::{uninitialized, zeroed}` that are known to cause undefined
  behaviour.][63346]

Compatibility Notes
-------------------
- Unfortunately the [`x86_64-unknown-uefi` platform can not be built][62785]
  with rustc 1.39.0.
- The [`armv7-unknown-linux-gnueabihf` platform is also known to have
  issues][62896] for certain crates such as libc.
