Re: [libvirt] [PATCHv2 00/21] Driver XML conf adjustment callbacks [READ FIRST]

This series implements the driver XML parsing callbacks as Dan suggested. This series may appear to be monstrous but I chose to split some patches to separate ones although the code does not compile afterwards to ease review. The patches starting with the word "fix" will need to be squashed into the non "fix" patches predceeding them. The last patch demonstrates the use of this code to get rid of the rest of the irrelevant fields in virCaps. I didn't go further with those to save time if there's a design flaw in the callback stuff.
