unittest output for the build farm

The build farm [hudson] can show test results if they are in an xml
format (it supports a couple).
 
There are several ways we can do this:
 - if all our tests are cppunit, the cppunit xml format can be
understood directly
 - if some of our tests are not cppunit (e.g. they are shell based, or
something adhoc) we can translate them to junitxml [via a few different
methods - I'll expand on that if we have non-cppunit tests]

Are all the test the build-tests do cppunit?
