squash! core/commands: Added 'log read' command

core/commands: Use a unidirectional channel for 'log read' output

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.

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.

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.

Queries now can be cancelled and the resources collected

ipfs blocks local returns _all_ local refs. For now this is one
long op. future commits will make it async.

'ipfs object stat' is a plumbing command to print DAG
node statistics. <key> is a base58 encoded multihash.
It outputs to stdout:

  NumLinks        int number of links in link table
  BlockSize       int size of the raw, encoded data
  LinksSize       int size of the links segment
  DataSize        int size of the data segment
  CumulativeSize  int cumulative size of object and references
