sync: fix broadcast bugs (#2135)
Make sure the tail mutex is acquired when `condvar` is notified,
otherwise the wakeup may be lost and the sender could be left waiting.
Use `notify_all()` instead of `notify_one()` to ensure that the correct
sender is woken. Finally, only do any of this when there are no more
readers left.
Additionally, calling `send()` is buggy and may cause a panic when
the slot has another pending send.
