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 :)

Christian Huitema c653e8502c Minor fixes in MDNS code to make sure it does work after the recent loop tightening. 
Suppressing the warning about mapping the 64 bit timeout value to a 32 bit integer,
based on the comments that the "maximum timeout used in practice is 6553500ms." If that
really is the case, we do not need to support 64 bit integers in the dict structure.
