CONTRIB: halog: sort URLs by avg bytes_read or total bytes_read

The patch attached to this mail brings ability to sort URLs by
averaged bytes read and total bytes read in HALog tool.
In most cases, bytes read is also the object size.
The purpose of this patch is to know which URL consume the most
bandwith, in average or in total.
It may be interesting as well to know the standard deviation (ecart
type in french) for some counters (like bytes_read).

The results:
- Sorting by average bytes read per URL:
