@jbenet cool with this?

This declarative style is simpler to compose than the imperative wiring
up of objects.

+ pass context to StartOnlineServices as parameter. one by one, trying
to remove dependencies on node state so these initialization steps can
be broken down.

@jbenet wasn't sure about the terminology here. I'm certain what I wrote
is not entirely correct. Feel free to edit.

@whyrusleeping @jbenet does passing this argument effectively instruct
the dagbuilder to pin recursively?

See the note:

// this file is only here to prevent go src tools (like godep) from
// thinking fuseversion is not a required package by non-darwin archs.

NB: daemon is one spot the repo lock is typically acquired

Try it out:

```
ipfs net diag --vis=d3 | diagnostics/d3/d3view
```

Notes: this is not the best way to do it, because it
breaks `--encoding=json`. Not sure what the best way is, and
right now this provides more utility than the other.

make vendor

The pkg.Interface style is modeled after heap.Interface. Generally, I
find it helpful for interfaces that have many implementations. It
provides clear distinction between the generic interface and the |n|
implementations that implement it (which may be interface types
themselves).

For clients who cannot keep the repo name, one can imagine that the most
likely rename is `ipfsrepo`. In that case, `ipfsrepo.Interface` remains
meaningful.

This is low-pri so it doesn't matter than much. But for the record, the
repo.Interface feels appropriate in this use-case.

it's unclear what this test case is meant to protect, but passing an empty datastore value no longer has bearing on node construction. Datastore setup now occurs in repo.
