There are cases that user do not want the event wait object to be allocated
automatically
in the stack as a temporary variable in nxevent_tickwait, since multiple
threads will
access the variable, they want to allocate the object as a global variable
for safety
control or easy debug. To solve this problem, this patch updated the
nvevent_tickwait
implementaion to give user the chance to pass the global wait object to it.
sched/event/event_wait.c:
add one more nxevent_wait_t *wait param to nvevent_tickwait.
nxevent_trywait create a temprary wait variable and then pass it to
nxevent_wait_t.
nxevent_wait create a temprary wait variable and then pass it to
nxevent_wait_t.
