Re: [libvirt] PATCH: 21/25: Use random_r for random numbers

Now that gnulib's rand module is imported, we have a decent quality random number generator that's portable. We don't want to mess with the apps state, so in virInitialize() we explicitly initialize our own private random nubmer generator state with virRandomInitialize(). The util.h file gains a convenience macro, since random_r() is horrible to call and we need to protect our global state int virRandom(int max)
