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.

* 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)

Allows to dynamically change the MutexProfileFraction to enable and
disable mutex profiling. It should be very useful for detecting
deadlocks, lock contention and general concurrency problems.
How to use:
To enable run: curl -X POST -v 'localhost:5001/debug/pprof-mutex/?fraction=10
To disable: curl -X POST -v 'localhost:5001/debug/pprof-mutex/?fraction=0'
Fraction defines which fraction of events will be profiled. Higher it is
the lower performance impact but less reliable the result.
To fetch the result use:
go tool pprof $PATH_TO_IPFS_BIN http://localhost:5001/debug/pprof/mutex

Moved the fmt.Printf call from ManageFdLimit() to the calling code. ManageFdLimit() is called by tests and its annoying to have it output text

Raising FD limits was erroring when the OS's max was at the maximum signed integer value. Switched the code to using uint64 instead of int64.

Resolves#5249. Calls multiaddr-dns, and picks the first result.
Uses a fixed timeout of 10 seconds. Adds test cases for one, multiple,
and no DNS results.
