  Log:
  HAMMER 4/many - more core infrastructure
  
  * Add reserved areas for a boot area and a memory log.
  
  * Add merged scan operations which are the core procedures used to execute
    most filesystem operations.  These functions will access both the
    in-memory tree of unsynchronized information and the on-disk topology
    to generate a 'merged' result.
  
    Amoung other things this allows the filesystem to hold operations in a
    memory cache without actually having to mess with the HAMMER topology
    on-disk.  The on-disk topology is then updated in a deferred manner.
    Disk I/O is entirely avoided for self contained operations which create,
    write, and delete related files quickly enough.
  
  * Add unmount sequencing, make mount and df work again.
  
  * Test the reference counting and flushing system on most primary
    structures.
  
  * Test basic buffer cache interactions, reading, writing, and lazy
    synchronization.
  
  * Start tying VNOPS into the infrastructure.  open/close/read/write works
    now via the in-memory cache (none of it is synched to the disk topology
    yet!).  readdir doesn't yet work... the 32 bit cookies are not large
    enough.
