[libvirt] [PATCH] util: changing all the "enum" structures into typedef's in "src/util/" directory.

[Julio Faracco]

Yes, I choose to do all this mechanical changes first and after I would
change some particular modifications according the previous
those mechanical changes.

First, I would like to change enum's to typedef's.

Thanks for your suggestions, Eric. It was so helpful.
Specially for the short commit message.
I forgot to check it when I sent my patch.
