Persist info about subresources on pages for DNS pre-resolution
The DNS pre-resolution system already "learns" what domains are commonly
needed when rendering sub-resources of a page at a given domain.
This patch saves (some of) the information learned into a persistent
pref, and restores it on startup.
For now, I put in a wimpy pruning of the list each time I save, so that
the list will not grow endlessly from session to session. I probably need
a better pruning algorithm, such as one that prunes after a given amount
of time, rather than only during shutdown. For now, this should get
a lot of nice results, and provide slightly larger than needed lists to
users that have long lived sessions, which is similar to the current
performance, where I didn't persist any info, and only pruned (actually
discarded) all learned info at shutdown.
