Summary: apachebench keepalive option sends an incorrect number
of requests

patch to fix ab.c ton only send the correct number of requests for keepalive
sessions
ab -k -n 1 http://www.example.com/
will send more than one GET request. The problem is worse for higher
concurrency levels. The issue is how the started connections is counted.
I first discovered this watching a tcp dump of ab at work. It would
consistently send one extra GET request per connection and then close the tcp
session before the reply would return. Resulting in a TCP RST packet.
I'm attaching a patch that actually simplifies the accounting of started
requests and prevents apachebench from starting more requests than it should.
