Subject: [PATCH] Fix some format string warnings with possible format string
vulnerability
To: libvir-list@redhat.com
For https://bugzilla.gnome.org/show_bug.cgi?id=761029
Decorate every method in libxml2 with the appropriate
LIBXML_ATTR_FORMAT(fmt,args) macro and add some cleanups
following the reports.
