hammer2 - Change from splay -> red-black tree
* Even though splay trees are faster they are not lookup-safe under a
shared lock. In order to consolidate the chain locks with the cache
coherency state we need to make lookups shared-safe.
* This will allow me to move chain locks from exclusive to shared/exclusive
with only modest surgery.
