  Log:
  HAMMER 53D/Many: Stabilization
  
  * Fix an overwrite bug with direct write which could result in file
    corruption.
  
  * Reserve just-freed big blocks for two flush cycles to prevent HAMMER from
    overwriting destroyed data so it does not become corrupt if the system
    crashes.  This is needed because the recover code does not record UNDOs
    for data (nor do we want it to).
  
  * More I/O subsystem work.  There may still be an ellusive panic related
    to calls to regetblk().
