Improve deferred function calls

1) Check vs. number of allowable deferred function calls is made at
link time.

2) Added a check for whether hook_call_deferred() has been made after
the start of calculating the time when the hook task should wake.  If
it has, go back and recalculate the wake time.  This works around a
race condition.
