Maintainer request: Update MASTER_SITES to use https, but keep http entries
as backup.

[jrm]

Follow mat's suggestion and only list
https://download.dnscrypt.org/dnscrypt-proxy/ since https redirects to http
for this site.

So,

$ distilator .
200 [DISTFILE]  https://download.dnscrypt.org/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz
200 [WWW]       http://dnscrypt.org
500 [DISTFILE]  https://www.dns-lab.com/downloads/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz
200 [DISTFILE]  http://www.dns-lab.com/downloads/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz

(from ports-mgmt/distilator)

It is right in saying the second one is an error, it does not work:

$ curl -I https://www.dns-lab.com/downloads/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz
curl: (7) Failed to connect to www.dns-lab.com port 443: Connection refused

As for the last one:

$ curl -I http://www.dns-lab.com/downloads/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz
HTTP/1.1 301 Moved Permanently
Date: Mon, 19 Dec 2016 19:10:44 GMT
Server: Apache
Location: http://dns-lab.com/downloads/dnscrypt-proxy/dnscrypt-proxy-1.8.1.tar.gz
Content-Type: text/html; charset=iso-8859-1

You should drop the www. from it, as it redirects anyway.
