[Libvir] [PATCH] Check calls to printf-like functions (and some fixes)

* Check calls to printf-like functions (and some fixes) * Fix qemudDebug when debug not enabled * Fix TODO so it doesn't supply a semi-colon (and all calls to this macro) * Add vim/emacs local variables in several places AFAICS this doesn't break the Python API build script, which was the objection to Jim Meyerling's previous patch to do much the same (http://www.redhat.com/archives/libvir-list/2006-March/msg00065.html). Rich.
