Add new stats expired_unfetched, evicted_unfetched

The two stats represent items which expired and memory was reused, and valid
items which were evicted, but never touched by get/incr/append/etc
operations in the meantime.

Useful for seeing how many wasted items are being set and then rolling out
through the bottom of the LRU's.
