Implement prefetching in chrome
With this CL (see also issue 2910009), chrome will support basic
prefetching. You can optionally deactivate prefetching with the
command line argument --disable-prefetch.
A new RequestPriority was created as well, IDLE, which is lower
than LOWEST. Unfortunately, SPDY has only two bits for priority, so
as a temporary measure (pending SPDY v3 which will have three), we
have a mapping in SPDY that folds net::LOWEST and net::IDLE together.
BUG=13505
