Commit Message

Add hash flooding protection, tests, and fix optimization

A random hash seed is used per instance so that an attacker cannot
construct an attack that causes the cache to become ineffective (the
admission policy would retain the existing entries).

The additional unit tests (to fix lack of coverage) showed that the
reset optimization to round down odd counters was over eager. It was
designed for items mapped to a single counter, not multiple like in a
CMS. As a larger sample period is beneficial, we divide the odd count
by four so the size never goes negative.
