This patch refactors the test suite:
- Instead of always generating the documentation with the available
rustdoc version, we now store generated documentation for all
supported rustdoc versions in the test/html directory.
- Instead of using one snapshot per test case, we now use one snapshot
per test case and rustdoc version.
This patch adds three build scripts for the sr.ht CI:
- archlinux.yml is the main build script. It builds the project using
the latest stable release from rustup and executes the tests, clippy
and rustfmt. The build also runs the reuse tool to check compliance
with the reuse specification and verifies that the last commit is
signed by me.
- archlinux-msrv.yml builds and tests the project on the MSRV, currently
Rust 1.40.0.
