* network: Use "one shot" protocol handler.

Add two new `NetworkBehaviour`s, one handling remote block requests
and another one to handle light client requests (both local and from
remote). The change is motivated by the desire to use multiple
substreams of a single connection for different protocols. To achieve
this, libp2p's `OneShotHandler` is used as a protocol handler in each
behaviour. It will open a fresh substream for the duration of the
request and close it afterwards. For block requests, we currently only
handle incoming requests from remote and tests are missing. For light
client handling we support incoming requests from remote and also
ported a substantial amount of functionality over from
`light_dispatch.rs` (including several tests). However the result lacks
in at least two aspects:

(1) We require external updates w.r.t. the best block per peer and
currently nothing updates this information.
(2) We carry a lot of peer-related state around.

Both aspects could be simplified by externalising peer selection and
just requiring a specific peer ID where the request should be sent to.
We still have to maintain some peer related state due to the way
libp2p's swarm and network behaviour work (e.g. we must make sure to
always issue `NetworkBehaviourAction::SendEvent`s to peers we are
connected to, otherwise the actions die a silent death.

Another change implemented here is the use of protocol buffers as the
encoding for network messages. Certain individual fields of messages
are still SCALE encoded. There has been some discussion about this
in another PR (https://github.com/paritytech/substrate/pull/3452), so
far without resolution.

* Add command-line flag to enable yamux flow control.

We never enabled proper flow-control for yamux streams which may cause
stream buffers to exceed their configured limit when the stream
producer outpaces the stream consumer. By switching the window update
mode to on-read, producers will only receive more sending credit when
all data has been consumed from the stream buffer. Using this option
creates backpressure on producers. However depending on the protocol
there is a risk of deadlock, if both endpoints concurrently attempt to
send more data than they have credit for and neither side reads before
finishing their writes. To facilitate proper testing, this PR adds a
command-line flag `use-yamux-flow-control`.

* Fix tests

* Clarify code a bit.

* Move code around.

* Introduce `Order`.

* Introduce `Link` structure.

* Get rid of ptr_offset

This is beneficial since ptr_offset is essentially makes us handle two different address spaces, global (i.e. `mem`) and heap local and without it things are becoming simpler.

* Rename PREFIX_SIZE to HEADER_SIZE.

This will come in the next commits.

* Introduce a separate `Memory` trait.

This is not necessary, but will come in handy for the upcoming changes.

* Rename `ptr` to `header_ptr` where makes sense.

* Introduce a `Header` type.

* Make `bump` dumber.

This allows us to pull `HEADER_SIZE` to see that we actually allocate `order.size() + HEADER_SIZE`.

* Clean up.

* Introduce a freelists struct.

* Update documentation.

* Make Sized requirement optional to make the PR truly back-compatible.
