[libvirt] [PATCH 0/3] Fix remote dispatch code trying to allocate 0-sized return buffers

[Erik Skultety]

This happens because of the switch to glib whose method g_malloc0 actually
correctly returns NULL on size 0 which doesn't make sense to do. The outcome of
that is that because virAllocN always returns 0, the dispatch code never fails
allocation and passes the NULL pointer to the server-side public API which
actually checks that and fails.
