  Avoid dealing with buffers in bdwrite() that are from other side of
  snaplock divisor in the lock order then the buffer being written. Add
  new BOP, bop_bdwrite(), to do dirty buffer flushing for same vnode in
  the bdwrite(). Default implementation, bufbdflush(), refactors the code
  from bdwrite(). For ffs device buffers, specialized implementation is
  used.
  
  This commit changes KPI/KBI, thus recompilation of out of tree kernel
  modules is required.
