* Grow noise buffers dynamically.
Currently we allocate a buffer of 176 KiB for each noise state, i.e.
each connection. For connections which see only small data frames
this is wasteful. At the same time we limit the max. write buffer size
to 16 KiB to keep the total buffer size relatively small, which
results in smaller encrypted messages and also makes it less likely to
ever encounter the max. noise package size of 64 KiB in practice when
communicating with other nodes using the same implementation.
This PR repaces the static buffer allocation with a dynamic one. We
only reserve a small space for the authentication tag plus some extra
reserve and are able to buffer larger data frames before encrypting.
* Grow write buffer from offset.
As suggested by @mxinden, this prevents increasing the write buffer up
to MAX_WRITE_BUF_LEN.

* For some reason my IDE ignored libp2p-kad
Instead of closing the connection on an error on the inbound substream
(both on `poll_next` as well as `poll_close`), one can set it to None
and depend on the remote to open an new one in case they have more data
to send.

* Add pnet protocol
copied from plaintext protocol, since that seems to be the closest match
* Minimalize the pnet protocol
* WIP private swarms with fixed key

Basically a stripped down and modified version of async_std BufWriter that
also encrypts using the given cipher.

Use From<Topic> instead of Into<String>
Use impl Into<Topic> instead of Topic in public API

The current implementation defines the InboundUpgrade only for `R = ()`
so notably a `NoiseConfig` created by `NoiseConfig::ik_dialer` can not
be an `InboundUpgrade`.
Fixes#1378.
- Pin `futures_codec` to version 0.3.3 as later versions require
at least bytes-0.5 which he have not upgraded to yet.
- Replace `futures::executor::block_on` with `async_std::task::block_on`
where `async-std` is already a dependency to work around an issue with
`park`/`unpark` behaviour.
- Use the published version of `quicksink`.
