Compact readout when more than 1 simultaneous downloads are going on

If more than 1 simultaneous downloads are going on, use more compact
format in readout. Currently, at most 5 download stats are displayed.

util::abbrevSize() is rewritten to support "Gi" unit and provides more
compact abbreviation.
