  Log:
  This patch removes the VOP_BWRITE() vector.
  
  VOP_BWRITE() was a hack which made it possible for NFS client
  side to use struct buf with non-bio backing.
  
  This patch takes a more general approach and adds a bp->b_op
  vector where more methods can be added.
  
  The success of this patch depends on bp->b_op being initialized
  all relevant places for some value of "relevant" which is not
  easy to determine.  For now the buffers have grown a b_magic
  element which will make such issues a tiny bit easier to debug.
