Alexander Motin d057807ede Switch refcount tracking from lists to AVL-trees. ...

With large number of tracked references list searches under the lock
become too expensive, creating enormous lock contention.

On my tests with ZFS_DEBUG enabled this increases write throughput
with 32KB blocks from ~1.2GB/s to ~7.5GB/s.
