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.
