Big cleanup, less code and more functionalities, yay !

shouldn't we add a couple of device (one disk, one net) for good measure here ?

One thing i'm wondering is if we couldn't do single instance XML definitions
for tests including the domains, network, etc... just reusing the new routines
to parse up the full set. that way a test could be defined as a single
standalone file, we could also easilly get testing of the full set of parsing
code just by using the test driver pointing to xml test instances.
This just push the actual test configuration one step further, and
actually I would not be too annnoyed to break some existing support in the
test driver to gte that more complete and convenient coverage.
What do you think ?
+1 for the patch
