The change to use arrays instead of linked-lists exposed a tiny bug in
the virReallocN function. The realloc() contract says that if size is
zero, then its semantics are the same as free(). virReallocN wasn't
matching this, instead returning failure, and not setting the original
pointer to NULL as expected. I've just committed this patch to fix this
bug which was causing test suite crashes
