CONFIGRET CONFIGMG_Call_At_Appy_Time(CMCALLBACKHANDLER Handler, ULONG ulRefData, ULONG ulFlags)
CONFIGMG will call back the handler at appy time.
This function is functionally equivalent to SHELL_CallAtAppyTime, but allow CONFIGMG to know that it is appy time.
This function is asynchronous (that is, callable at interrupt time), reentrant, and fast.
