Turns out that `pool.Put(buf)` had to *allocate* because we needed to turn
`[]byte` into `interface{}`. Apparently, we've never done this correctly we just
never noticed because we never really used buffer pools extensively.
However, since migrating yamux to a buffer-pool backed buffer, this started
showing up in allocation profiles.

* go-datastore and friends: GetSize
* badger: new release, fewer allocations
* go-mplex: send fewer packets
* go-bitswap: pack multiple blocks in a single message, fewer allocations
* go-buffer-pool: replace the buffer pool from go-msgio
* yamux: fixed data race and uses go-buffer-pool for stream read-buffers to
reduce memory and allocations.
* go-libp2p-secio: get rid of a hot-spot allocation
* go-libp2p-peerstore: reduced allocations (at the cost of some memory)

* Most of our datastores barf on non []byte values.
* We have to have a bunch of "is this a []byte" checks.
* Saves some allocations.

Currently the "path" module does two very different things:
* Defines how ipfs paths look like and provides tools to parse/split etc.
* Provides a resolver to resolve paths.
This moves the resolver stuff to `path/resolver` and leaves the
path utilities in `path`.
The result is that now the IPFS `path` package just defines what a path
looks like and becomes a module that can be exported/re-used without problems.
Currently there are circular dependency cycles (resolve_test -> merkledag/utils,
merkledag->path), which the prevent the export of merkledag itself.

* Change ResolveToCid to take a Resolver and a NameSystem instead of an ipfs
Node.
* Make the pin/unpin methods use a Unixfs path resolver.

Also change existing 'Node' type to 'ProtoNode' and use that most
everywhere for now. As we move forward with the integration we will try
and use the Node interface in more places that we're currently using
ProtoNode.

This change adds the /ipfs/bitswap/1.1.0 protocol. The new protocol
adds a 'payload' field to the protobuf message and deprecates the
existing 'blocks' field. The 'payload' field is an array of pairs of cid
prefixes and block data. The cid prefixes are used to ensure the correct
codecs and hash functions are used to handle the block on the receiving
end.
