Cause the buffer to reset it's lifetime
the standard custom layer context pointer
the id of the buffer to receive the signal
non-zero on success, when the buffer exists, zero otherwise
When a buffer's end signal is sent, it's managed scope is cleared, as if it had been destroyed and recreated, and the buffer end hook is run on the buffer. The upshot of this is that it is as if the buffer were closed and re-opened except that it still has the same id.
