-------------------------------------

I've split the Memory change out into CASSANDRA-8726, and will upload a version omitting it
and the BF change shortly.

> There are still a few bugs with resource management, especially around SSTableReader

"simplify" the logic in SSTableReader to not track the replacement chain, only to take a new
reference to each of the underlying resources.
