  HAMMER 12/many - buffer cache sync, buffer cache interactions, misc fixes.
  
  As of this commit all vnops work, the filesystem remains consistent across
  umount/remount, and the 'cpdup / /mnt/root' test succeeds.  There is still
  a ton of work to do but this is a major milestone.
  
  * Get sync and umount working properly.  Properly sync out in-memory records
    and inode updates, and properly release buffer cache buffers so the
    kernel can throw them away.
  
  * Modifications to buffers backed by the buffer cache ensure that any
    asynchronous writes complete to avoid a modify-write race.
  
  * Fix miscellanious reference counting bugs.
  
  * Fix two insertion bugs for internal B-Tree nodes that were causing the
    code to blow up.
