Merge branch 'upstream-sid' into debian-sid

Conflicts:
	lib/codereview/codereview.py
	lib/time/zoneinfo.zip
	src/pkg/go/types/testdata/expr1.src
	test/fixedbugs/issue5105.dir/a.go
	test/fixedbugs/issue5260.dir/a.go

In the end, I extracted go1.1.src.tar.gz and used cp -r /tmp/go/* .

To be honest, I still don’t understand why git-import-orig yields merge
errors at all or how that workflow is supposed to work. If someone could
enlighten me, I’d be happy.
