[PATCH 00/17] conf/qemu/etc: change several functions to return void instead of 0/-1

This started with me noticing one function call that checked for failure on something that I knew couldn't fail. So I changed that function to return void. But then I noticed another similar function that also should return void, so I changed that one too. Then eliminating the check for the return from those functions caused another function to become infallible, so I changed that one too, which led to more and more until the evening was finished and I had this long list of tiny mechanical patches. And here it is - an easy way to improve your review stats :-) P.S. I know there are more of these, but forced myself to stop here. A related question - is it possible for virObjectNew() to fail? I did finally find (after some searching, documentation that says g_object_new() can't return null, but I don't know enough about g_object stuff to know if the vir*Initialize functions could fail (for example). If virObjectNew() can't fail then that open a whole new can of worms...
