Diff to previous 1.74 (colored)

Merge from ad-namecache:

- Have a stab at clustering the members of vnode_t and vnode_impl_t in a
  more cache-conscious way.  With that done, go back to adjusting v_usecount
  with atomics and keep vi_lock directly in vnode_impl_t (saves KVA).

- Allow VOP_LOCK(LK_NONE) for the benefit of VFS_VGET() and VFS_ROOT().
  Make sure LK_UPGRADE always comes with LK_NOWAIT.

- Make cwdinfo use mostly lockless.
