Basically, this means renaming several things called data to info, which
is information about the statistics. Things that are named data now are
actual data stored for the statistic.

and add a disable method to disable tracing.

Make etherdump timestamps zero-based.
...
We previously used the actual wall time for the base timestamps,
making etherdumps non-deterministic. This fixes that problem and
gets rid of the "malformed packet" at the front that we needed to
provide the right base timestamp to wireshark/tcpdump.

Update stats for new prefetching fixes.
...
Prefetching is not enabled in any of our regressions, so no significant
stat values have changed, but zero-valued prefetch stats no longer
show up when prefetching is disabled so there are noticable changes
in the reference stat files anyway.

Fixes to get prefetching working again.
...
Apparently we broke it with the cache rewrite and never noticed.
Thanks to Bao Yungang <baoyungang@gmail.com> for a significant part
of these changes (and for inspiring me to work on the rest).
Some other overdue cleanup on the prefetch code too.
