- shared IPs facility, which allows using of a limited pool of client
IP-addresses by any number of virtual clients.
  This is actually opens the road to 100 000 - 200 000 and higher
simultaneous clients numbers.
- random client credetials, which allows using e.g. 100 simultaneous virtual
clients to simulate a load of e.g.
  1000000 clients by choosing client credentials randomly for each cycle;
- compilation, FTP, IPv6 bug-fixes;
- advanced to the latest curl-7.17.0.
