Re: [libvirt] [PATCH 4/9] Change code generator to give async event messages their own postfix

The naming convention for structs used in the RPC layer is for incoming requests to be called XXXX_args, and the associated outgoing reply to be called XXXX_ret. Asynchronously emitted messages (eg events) are re-using the XXXX_ret naming scheme. This patch changes that such that async messages are XXXX_msg, and stops adding entries for them in the dispatch table, avoiding the need for a dummy no-op implementation.
