There are cases that users do not want the event wait object to be allocated automatically in the stack as a temporary varialbe in nxevent_tickwait, since multiple threads will access the varialbe, they want to allocate the object as a global variable for safety control or easy debug. To solve this problem, this patch add a new function nxevent_tickwait_wait implementation to give user the chance to pass the global wait object to it.
