response time in varnishncsa

[Ken Brownfield]

Angelo's email address isn't valid anymore, so here's a patch against 2.1.5
for anyone interested in some extra fields.

The patch adds three fields to the end of the log line if you provide the -e
switch to varnishncsa:

   - long: Age in seconds
      - A 0 value doesn't necessarily mean it was a miss.
   - long: Hits; requires X-Hits header to be added in vcl_deliver():
      - set resp.http.X-Hits = obj.hits;
      - This doesn't seem to be available in the log, otherwise.
      - A 0 value means it was a miss.
   - float: Response time in seconds (resp-req)

Not heavily tested, v1.0, YMMV, etc., but it seems fine under load and
doesn't seem to leak.

I think adding LogFormat functionality (per the TODO) is the better
implementation, but that's outside the scope of my free time. ;)
