feat(core) replace config.Config with repo.Repo

@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?

move generic packages to thirdparty (see thirdparty/README.md)

core/mount: make non-darwin archs see fuseversion

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.

moved our d3view to own repo

d3view is now in its own repo:
https://github.com/jbenet/ipfs-diag-net-d3-vis

This is so we can iterate on it quickly without having to
needlessly waste CI resources.

The repo also installs it for you:

```sh
git clone github.com/jbenet/ipfs-diag-net-d3-vis d3view
cd d3view
sudo make install
```
