Because json.NewDecoder(r).Decode(&v) doesn't necessarily consume all
data on the reader, that means an HTTP connection can't be reused. We
don't do a lot of HTTP traffic where we read JSON responses, but the
discovery is one such place. The other two are for POSTs from the GUI,
where it's not exactly critical but still nice if the connection still
can be keep-alive'd after the request as well.
Also ensure that we call req.Body.Close() for clarity, even though this
should by all accounts not really be necessary.

1. Removes separate relay lists and relay clients/services, just makes it a listen address
2. Easier plugging-in of other transports
3. Allows "hot" disabling and enabling NAT services
4. Allows "hot" listen address changes
5. Changes listen address list with a preferable "default" value just like for discovery
6. Debounces global discovery announcements as external addresses change (which it might alot upon starting)
7. Stops this whole "pick other peers relay by latency". This information is no longer available,
but I don't think it matters as most of the time other peer only has one relay.
8. Rename ListenAddress to ListenAddresses, as well as in javascript land.
9. Stop serializing deprecated values to JSON

This happens automatically in the background anyway, and it can take a
long time on low powered devices at an inconvenient time. We just want
to get up and running as quickly as possible.

A potential practical use is to encode a short version of the hostname
at the beginning of the device ID.
For example:
jb@syno:~/s/g/s/s/c/stvanity $ stvanity abc
Want 15 bits for prefix "ABC", about 3.3e+04 certs to test (statistically speaking)
Found ABCFPWS-JKDIFV3-E5IUAQW-DK53WVR-HY7XWBS-56H33GR-CJQI67Q-VGXRMAW
Saved to cert.pem, key.pem
jb@syno:~/s/g/s/s/c/stvanity $ stvanity $(hostname)
Want 20 bits for prefix "SYNO", about 1e+06 certs to test (statistically speaking)
Trying 554 certs/s, tested 8307 so far in 15s, expect ~32m total time to complete
Trying 543 certs/s, tested 16277 so far in 30s, expect ~32m total time to complete
...
The rest is just a matter of patience.
jb@syno:~/s/g/s/s/c/stvanity $ stvanity syncthing
Want 50 bits for prefix "SYNCTHI-NG", about 1.1e+15 certs to test (statistically speaking)
Trying 529 certs/s, tested 7941 so far in 15s, expect ~67443 years total time to complete

When run without parameters, attempts to listen for local discovery
announcements just like Syncthing, and prints them.
With -send, it also sends fake discovery packets. This can be used on
two or more computers simultaneously to verify that they can see each
other.
