This changes the CI / release builds to use the latest Go version. It also upgrades golangci-lint to a newer version compatible with Go 1.19. In Go 1.19, godoc has gained official support for links and lists. The syntax for code blocks in doc comments has changed and now requires a leading tab character. gofmt adapts comments to the new syntax automatically, so there are a lot of comment re-formatting changes in this PR. We need to apply the new format in order to pass the CI lint stage with Go 1.19. With the linter upgrade, I have decided to disable 'gosec' - it produces too many false-positive warnings. The 'deadcode' and 'varcheck' linters have also been removed because golangci-lint warns about them being unmaintained. 'unused' provides similar coverage and we already have it enabled, so we don't lose much with this change.
