On the point of LTS distro compatibility, I looked into what Rust will be required by Firefox ESR, since that's the most likely reason for older distros to need to update rustc. According to their release calendar, the next ESR will be 78, and their Rust update policy says 78 will require Rust 1.43, which is currently in beta. Thus, this PR would only affect the next ESR after that.

CI should be fixed now, in case that push didn't notify...

@bors r+

Thank you for checking the ESR version requirements from Firefox. We should probably document our "reasons" for choosing a given LLVM version as the oldest one we support, and that seems like a good start...

Pkgsrc changes: * Remove a couple diffs which are now integrated upstream. * Adjust cargo checksums after upstream upgrades. * Belatedly bump the curl dependency * Unset DESTDIR during the build phase, to work around a mysterious build bug deep in the bowels of llvm. * Bump nearly all bootstraps to 1.43.1. Upstream changes: Version 1.44.0 (2020-06-04) ========================== Language -------- - [You can now use `async/.await` with `#[no_std]` enabled.][69033] - [Added the `unused_braces` lint.][70081] **Syntax-only changes** - [Expansion-driven outline module parsing][69838] ```rust #[cfg(FALSE)] mod foo { mod bar { mod baz; // `foo/bar/baz.rs` doesn't exist, but no error! } } ``` These are still rejected semantically, so you will likely receive an error but these changes can be seen and parsed by macros and conditional compilation.
