this patch added full context switch support for scheduling, it make sure each VCPU has its own stack, and added host_sp field in struct sched_object to record host stack pointer for each switch out object. Arch related function arch_switch_to is added for context switch. To benefit debugging, a name[] field is also added into struct sched_object.
