schedule: add full context switch support

Browse Source 
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.
