Macro for testing the version you are compiling with
Macro for testing the version you are compiling with

Added a macro similar to the GLib's GLIB_CHECK_VERSION so that one can
simply do something like:

 #if LIBVIR_CHECK_VERSION(1,1,3)
   /* Call function here that appeared in 1.1.3 and newer */
   virSomeNewFunction();
 #endif
