lgtm.

I care enough for the go environment to keep the go bindings
working. I've updated the bindings, the build infrastructure and the
notmuch-addrlookup utility to go 1. I'll send a patch series as a
followup that is meant to be applied upon Austins patch.

The last patch in the series is a cleanup of the source code done with
the gofmt utility. Go is somewhat strict in its coding conventions,
but there is a utility that magically formats code. This makes the go
code in the wild remarkably consistent. We should stick to the
conventions too, hence this patch even if it breaks git blame
somewhat.

I haven't tested the bindings in depth, but the notmuch-addrlookup
utility seems to be working fine.

Cheers,
Justus
