Increase the size of the QHostInfo cache.
This change increases the size of the DNS cache in QHostInfo from 64
entries to 128. Given the figures in the google chrome performance paper
http://www.igvita.com/posa/high-performance-networking-in-google-chrome/
this should mean we can cache enough entries to handle 4 tabs at once.
(cherry picked from commit fd9013658bab096839154ae6e68adfd1a4e10189)
