Range filter: late_ranges functionality.
Add one more filtering point after postpone filter. This allows to serve
range capable replies with subrequests. It's not as efficient as range
filtering for static data (i.e. doesn't save us from reading data from
disk if some filter needs them in memory), but it may save some network
bandwidth for us and for our users.
