- Remove
CVE-2018-1000622-prevent-rustdoc-loads-uncontrolled-plugins-path.patch,
since rustdoc plugins are fixed since version 1.27.1 (bsc#1100691,
CVE-2018-1000622).

- Update to version 1.31.1
+ Fix Rust failing to build on `powerpc-unknown-netbsd`
+ Fix broken go-to-definition in RLS
+ Fix infinite loop on hover in RLS

- Update to version 1.31.0
+ Language
- This version marks the release of the 2018 edition of Rust.
- New lifetime elision rules now allow for eliding lifetimes in functions and
impl headers. E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
`impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
in structs.
- You can now define and use `const` functions. These are currently
a strict minimal subset of the const fn RFC. Refer to the
[language reference][const-reference] for what exactly is available.
- You can now use tool lints, which allow you to scope lints from external
tools using attributes. E.g. `#[allow(clippy::filter_map)]`.
- `#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
a crate, not just in exported functions.
- You can now use parentheses in pattern matches.
+ Compiler
- Updated musl to 1.1.20
+ Libraries
- You can now convert `num::NonZero*` types to their raw equivalvents using the
`From` trait. E.g. `u8` now implements `From`.
