Serapheim Dimitropoulos abd0b59e48 Livelist logic should handle dedup blkptrs
Update the logic to handle the dedup-case of consecutive
FREEs in the livelist code. The logic still ensures that
all the FREE entries are matched up with a respective
ALLOC by keeping a refcount for each FREE blkptr that we
encounter and ensuring that this refcount gets to zero
by the time we are done processing the livelist.

zdb -y no longer panics when encountering double frees
