License-Update: change license checksums to check the License files themselves (BSD3 and GPL2),
and the tool-to-license file (LICENSE). Changes to LICENSE will now be
detected.
Backport a patch to fix the build with musl.
Drop upstreamed patch.
Update libidn build-dependency to libidn2.
Patch in an install target and use that to install binaries, to avoid upstream
adding binaries that we don't ship. Also ship all binaries that are installed.
