chardev: Allow frontends to notify backends of guest open / close
Some frontends know when the guest has opened the "channel" and is actively listening to it, for example virtio-serial. This patch adds 2 new qemu-chardev functions which can be used by frontends to signal guest open / close, and allows interested backends to listen to this.
