  Log:
  Implement SYSREF - structural reference counting, allocation, and sysid
  management subsystem.
  
  * Structural reference count management, including creation and termination
    sequencing (e.g. where the structure might be temporarily referenced
    during termination).
  
  * Allocation.  It uses an objcache backend for optimal allocation,
    deallocation, and memory recovery.
  
  * Sysid assignment and red-black tree indexing.  It does this in the
    objcache CTOR and DTOR so it costs us absolutely nothing in the
    resource allocation / deallocation critical path.  sysids will be
    reused unless they are externally accessed.
