  Log:
  HAMMER 3/many - more core infrastructure.
  
  * Add an in-memory B-Tree node abstraction
  * Add an in-memory record abstraction.
  * Put the B-Tree cursor code in its own source file.
  * Fill in more of the VOP code.
  
  * Do a major clean-up of all in-memory structures and some on-disk
    structures.  All the major in-memory structures now use similarly
    named functions.
  
  * Move inter-cluster link from a B-Tree leaf node to a B-Tree internal
    node, giving us a left and right boundary to play with.  This simplifies
    the algorithms by quite a bit.
  * Allow the B-Tree to be unbalanced by moving the sub-type from the B-Tree
    node header to the B-Tree element structure.
  
  * Revamp the I/O infrastructure, in particular allow B-Tree nodes to be
    held passively.
  * Implement a flexible B-Tree node cache.  References into the B-Tree can
    be cached by inodes.  If the related buffer is flushed by the system, the
    related cache pointers will be cleared.
