SVN rev 205231 on 2010-03-16 22:17:21Z by kmacy
- reduce contention by breaking up ARC state locks in to 16 for data
and 16 for metadata
- export L2ARC tunables as sysctls
- add several kstats to track L2ARC state more precisely
- avoid holding a contended lock when atomically incrementing a
contended counter (no lock protection needed for atomics)
