Commit 759be3dad9 bumped our Go
requirement to 1.18 which allows us to drop support for old-style
`+build` tags. This change runs `go fix ./...` to remove them, and
updates some remaining code generators that produced `+build` lines.
* Update CI Go version to 1.20/1.19
* Update `golangci-lint` to v1.51.2
* Update coverage collection to use new Go 1.20 tools
* Update coverage job to only run on latest Go version
Fixes#367
* Bump CI to Go 1.19
* Update golang/go edwards25519 test
* Apply formatting to printer stubs output (to get correct comment formatting)
* Bump gofumpt version
As part of fixing failing third-party tests, this PR significantly
rearchitects their specification and execution.
Third-party tests are now specified in a much more flexible format allowing
more customization on a per-package level. In addition, third-party tests are
now used to auto-generate a Github Actions workflow to perform the tests in
parallel. This not only gives faster feedback on PRs, but will also allow us
to more quickly narrow down on which packages are failing. An additional
workflow also confirms that local execution of third-party tests is consistent
with the Github Actions version. This workflow only runs when tests/thirdparty
itself is changed.
