QEMU currently does not implement notification packets, so it should only send stop-replies synchronously and when requested. Nevertheless, it may still issue unsolicited stop messages through gdb_vm_state_change(). Although this behavior doesn't seem to cause problems with GDB itself, it does with other debuggers that implement the GDB remote serial protocol, like hexagon-lldb. In this case, the debugger fails upon an unexpected stop-reply message from QEMU when lldb attaches to it. Instead, let's change the gdbstub to send stop messages only as a response to a previous GDB command that accepts such a reply.

Now, let's add a test for this intended behavior. Running this test before the fix from the previous commit fails as QEMU sends a stop-reply packet asynchronously, when GDB was in fact waiting an ACK.
