Daniel Kahn Gillmor 9de4d6537b Implement sensible default padding policy. 
This commit changes the semantics of tls_query_padding_blocksize()
slightly.  Where previously both 0 and 1 meant "no padding", this
commit changes 1 to mean "pad using a sensible policy".

At NDSS 2017's DNS privacy workshop, I presented an empirical study of
DNS padding policies:

https://www.internetsociety.org/events/ndss-symposium/ndss-symposium-2017/dns-privacy-workshop-2017-programme#session3

The slide deck is here:
https://dns.cmrg.net/ndss2017-dprive-empirical-DNS-traffic-size.pdf

The resulting recommendation from the research is that a simple
padding policy is relatively cheap and still protective of metadata
when DNS traffic is encrypted:

 * queries should be padded to a multiple of 128 octets
 * responses should be padded to a multiple of 468 octets

Since getdns is only currently doing queries over tls, we only have to
implement the first part of this policy :)

Sara Dickinson f0f3c43552 - Add a new mode where for TLS (and infact TCP too) the upstream selection simply cycles over all the upstreams rather than treating them as an ordered list and always using the first open one. 
- Make IP field in debug output fixed width
- Collect all the one line config options at the top of the stubby.conf file to make it easier to read
