lib/defines: added configurable SRTT limits and lowered probing rate

This adds configurable SRTT limits for various network environments.
The probing rate is reduced from 10% to 1%, so that badly connected
nameservers are not selected as often. This is apparent on zone cuts
with a lot of nameservers, e.g. .com. With the probing rate set to
1% the average response time for 300 queries is almost 50% better:
