This:

- adds subdomain gateway support for ED25519 CIDs in a way that fits in
  a single DNS label to enable TLS for every IPNS website.

- cleans up subdomain redirect logic and adds more explicit error
  handling.

TL;DR on router logic:

When CID is longer than 63 characters, router at /ipfs/* and /ipns/*
converts to Base36, and if that does not help, returns a human readable
400 Bad Request error.

Addressing code review:

refactor: use b36 for all libp2p-keys in subdomains

54b1969c correctly switched from nc to socat, but did not account for it
not being as widely available. Adjust tests that depend on it with the
correct message.

There are also a number of comments pertaining to nc - they were not
adjusted.

Differences between bsd-netcat and gnu-netcat make it horrible tool

Instead of repeatedly starting the netcat server, start it once and wait for it
to fully start. Then, feed responses in using a fifo.

We don't need to do this for every test and our tests are slow enough.

Also:

* Disable bootstrapping
* Listen on random ports
* Write temporary files to the current (trash) directory instead of temp (easier
  to find, collected by Jenkins).
* Fix indentation.

Reimplement http-request proxying ala httputil.ReverseProxy.

NB: this is proxies the request synchronously (sends all request-body
before reading any response).
