[Libvir] [PATCH] #include "config.h" needed

There is one file missing: #include "config.h" which ought to be included at the beginning of every C file. If missing, it causes problems on Windows -- in particular the C99 keyword 'restrict' won't be recognised and that causes compile errors all over the place. I've also changed a few <config.h> --> "config.h", which I think is more correct because config.h is a local file and should never come from the system include files (CC'd to Jim Meyering -- is this right in your opinion?)
