Packages to extract from go-ipfs

[whyrusleeping]

We don't want to depend directly on ipfs. It makes dependency management really un-fun in a lot of ways. To avoid doing that, we need to extract the following packages from ipfs into their own repos:

• github.com/ipfs/go-ipfs/path"
• github.com/ipfs/go-ipfs/path/resolver"
• github.com/ipfs/go-ipfs/merkledag"
• github.com/ipfs/go-ipfs/importer"
• github.com/ipfsgo-ipfs/unixfs/io"
• github.com/ipfs/go-ipfs/exchange/bitswap"
• github.com/ipfs/go-ipfs/exchange/bitswap/network"

We already had this issue :) #197

oops >.>

bitswap is done, so is blockservice (indirect dep). Merkledag is ready to go (but not merged yet). I plan on getting the rest done by end of weekend.

merkledag is done, doing path stuff next

[whyrusleeping]

Path is nearly done. I realize that doing the importers stuff is going to be annoying because several people are working on PRs to parts of it...

Thanks to @whyrusleeping this is done now #695
