Now the hookid of a return type event(addevent.*.return)
should be an even number and its value should be the
corresponding entry event hookid +1.
The hookid of a non-return type event should be an odd
number.
Add the hookid of HOOKID_REGEVTDESC
* register_event.stp:
add register_evt_desc() to register the description of an event.
Change the register_sys_event() to add the an argument

representing the event description string, which could help
facilitate the error debugging.
