[PATCH] support/ab.c improved for test more paths at once and better statistics

[Novak Jiri <XN...@cs.felk.cvut.cz>]

Hallo,

   After patch, ApacheBench is able to read file with paths to test on
WWW server. Paths are not full URL, only path on same WWW server.
It's able to process them repeatly by each path or by whole
file. I improved statistics too, now it can print stats for each 
request/path/run.

urlfile:
/index.html
/credits.html
....

new options:
    -f urlfile      File containg urls for test (only /paths!)
                    Number of requests will be equal to number of urls
    -m mode         0=, 1=each url will be repeated 'repeat' times,
                    2=whole e will be repeated 'repeat' times
    -r repeat       Operations will be repeated 'repeat' times
    -s statmode     Mode of printing statistics
                    0=stats per url, 1=stats per repeated run
                    2=statsequest, -1=all

tested on:
   Linux 2.0.33, gcc 2.7.2.3, libc.so.5.4.38

oposite WWW:
   Apache Netscape-Enterprise/3.6, Apache/1.3.0
