[JDEV] testing tools

[Dustin Puryear]

I've made a few changes to the testing suite. One affects performance of
the tools on the clients. In addition, I recently added nusers2.sh,
which automates the testing of testing n clients on two hosts passing x
messages per second for t seconds. It will also invoke sar on the Jabber
server if possible. 

As always you can grab the testing suite's source code at
http://www.sf.net/projects/jabbertest. If you want the binaries then
email me. Note that I will send you binaries compiled with the expat
library, so each binary will be about 1MB.

Here is some sample data gathered using nusers2.sh using 128 users
passing 2 messages/sec (test messages < 128 bytes) for 60 seconds:

$ ./nusers2.sh crack 128 2 60 test_
Start time: 14:28:58
*** Copying clients..
*** Starting sar on server..
--- Sleeping 5 * 4 seconds for idle data..
*** Starting receivers..
*** Testing start..
*** Starting senders..
