This patch series introduces support for the Multi-Core Debug (MCD) API, a commonly used debug interface by emulators. The MCD API, defined through a header file, consists of 54 functions for implementing debug and trace. However, since it is a header-file-only interface, MCD does not specify a communication protocol. We get around this limitation by following a remote procedure call approach using QMP. The client stub corresponding to this implementation can be found at https://gitlab.com/lauterbach/mcdrefsrv
