hammer2 - per-node sync threads
* Change the per-pfs sync threads into per-node sync threads. Each sync
thread is responsible for synchronizing its particular node to the
pfs-based cluster when its particular node is out-of-sync.
* Significant work to the cluster iteration code to fix numerous deadlocks.
* Call vclrisdirty() conditionally at end of flush.
* Do not call vclrisdirty() unconditionally in hammer2_vop_fsync().
* Misc cleanups.
