[RESEND,v6,32/36] multi-process/mon: stub functions to enable QMP module for remote process

From: Elena Ufimtseva <elena.ufimtseva@oracle.com>

QMP module doesn't need some functions to run independently on the
remote processes. However, these functions are necessary for
compilation. Therefore, these functions are stub'ed out. The
stub functions raise an assert if QEMU is built in debug mode
(--enable-debug).
