AU: Push seeks in http fetching to the progress percentage.

AU: Push seeks in http fetching to the progress percentage.

The updater was reporting status as a fraction of bytes downloaded vs
total, ignoring any bytes that were skipped due to resuming an
upload. The result was that a user may see progress go from 0 to 60
percent, then reboot, then see progress go from 0 to 40 percent, then
finish.

This CL allows an HTTP fetcher to report to the delegate that it's
seeking to a particular offset.

LGTM w/ a suggestion. I guess this is much easier than reporting the number of
completed operations out of total :-)

prefs.cc:40: LOG(ERROR) << "Unable to read prefs from " << filename.value()
Use PLOG instead? Also, I'd change it to a warning to not freak out random
people looking at logs.
