Botond Dénes 11105cbb78 reader_concurrency_semaphore: make inactive read handles unique across semaphores ...

Currently inactive read handles are only unique within the same
semaphore, allowing for an unregister against another semaphore to
potentially succeed. This can lead to disasters ranging from crashes to
data corruption. While a handle should never be used with another
semaphore in the first place, we have recently seen a bug (#6613)
causing exactly that, so in this patch we prevent such unregister
operations from ever succeeding by making handles unique across all
semaphores. This is achieved by adding a pointer to the semaphore to the
handle.
