[libvirt] [test-API PATCHv2 2/2] repo: Add test for mutualy exclusive console access



This test case checks if the console connection code works in a safe way
that the connection don't get messed up.
---
Diff to v1:
-- removed semicolons at the end of statements (the C language left some habits :D)
-- added call to usage function (I thought it's called automaticaly. With this this could
                                 be another good function to incorporate in the class and 
                                 free the test-writer from re-implementing it again and again)
-- added cleanup function (same comment as above; note: there are some tests that don't have this func.)
-- refactored getting of optional parameter "device"
-- added cleanup of stream objects (they'd got cleaned up automaticaly with the disconnect, but
                                    this is safer and enables testing if the stream was in a good state)
