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 471e8725e2 Change the default profile for Stubby to use TLS then UDP/TCP 
- this will only try over TLS a few times before backing off to clear text
  - but makes the default  for Stubby opportunistic privacy (Willem - WDYT?)
Also use padding and ECS privacy by default for Stubby.
More debugging to help users when there are failures or fallbacks.
Also remove a few help options from Stubby that don't apply
Add -v to output version on getdns_query/stubby
