Import golang/gddo at commit 20d68f94ee1f7547de2b1c68627253df20c8d45e
into daemon/server/httputils/internal/httputil.
The upstream repository was archived in 2021. Its history was filtered
to remove repository-specific CI and project files and rewritten to its
new location.
Strategy taken:
# install filter-repo (https://github.com/newren/git-filter-repo/blob/main/INSTALL.md)
brew install git-filter-repo
cd ~/projects
# create a temporary clone of gddo
git clone --single-branch --branch master --no-tags https://github.com/golang/gddo.git tmp_gddo
cd tmp_gddo
