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.

The progressbar should now correctly calculate the size of a directory (by
ignoring the directory sizes).

Make `Root` value explicitly a `Directory` structure instead of the `FSNode`
interface (which also allowed the `File` type). This helps to make the code
easier to reason about: the root of an MFS layout is always a directory, not a
(single) file.
Rename `GetValue()` to `GetDirectory()` to also make it more explicit, the
renamed function now returns a `Directory` so there is no need for type
assertions that were previously done on the `FSNode` interface to check that it
was actually a `Directory`.
`NewRoot()` now doesn't allow to create `Root` structures from DAG nodes that
contain UnixFS files.

This extracts the blocks/blockstore package and renames the
blocks/blockstore/util package to /blocks/blockstoreutil
(because util depends on Pin and I don't plan to extract
Pin and its depedencies).
The history of blocks/blockstore has been preserved. It has
been gx'ed and imported. Imports have been rewritten accordingly
and re-ordered.
