maxv 0bf8272f89 Introduce POOL_QUARANTINE, a feature that creates a window during which a 
freed buffer cannot be reallocated. This greatly helps detecting
use-after-frees, because they are not short-lived anymore.

We maintain a per-pool fifo of 128 buffers. On each pool_put, we do a real
free of the oldest buffer, and insert the new buffer. Before insertion, we
mark the buffer as invalid with KASAN. On each pool_cache_put, we destruct
the object, so it lands in pool_put, and the quarantine is handled there.

POOL_QUARANTINE can be used in conjunction with KASAN to detect more
use-after-free bugs.
