Understanding FreeRADIUS statistics

[dominic.stalder at unibe.ch]

Hi Alan

Just a short feedback after the first few tests: overall it looks much better and the corresponding statistics seem to be aligned now; thanks a lot for the quick fixes / patches!

- only the following two counters remain zero all the time, maybe there could be a little fix applied as well? __

FreeRADIUS-Total-Proxy-Access-Accepts = 0
FreeRADIUS-Total-Proxy-Access-Rejects = 0

Regards
Dominic
