Changes the count of a barrier.
barrier-change-count barrier new-count => result
A positive fixnum, or
barrier-change-count changes the count of the barrier barrier to new-count.
If the barrier is enabled and the arriver count is less than new-count, this just sets the count of the barrier to the new-count and returns
t. Otherwise, it calls
(barrier-unblock barrier :reset-count new-count)
