Title: use gopkg.in/errgo.v1

This is now the standard package path for the errgo package.

It is almost exactly the same as the existing github.com/juju/errgo package
except that it defines the Location method slightly differently so that
error stacks will work correctly even if multiple versions of the
errgo package are imported.
