dm bufio: add LRU abstraction
A CLOCK algorithm is used in this LRU abstraction. This avoids
relinking list nodes, which would require a write lock protecting it.
None of the LRU methods are threadsafe; locking must be done at a
higher level.
Code that uses this new LRU will be introduced in the next 2 commits.
As such, this commit will cause "defined but not used" compiler warnings
that will be resolved by the next 2 commits.
