    hammer2 - small-embedded-data fixes, syncer fixes
    * Add a bit of a hack to try to fix an issue where the embedded data
      would sometimes not get synchronized.  Add the DIRTYEMBED flag
      and test for it in various places.
    * Remove an improper call to hammer2_chain_modify() on the inode
      (the previous handling of embedded data, which was broken).
    * Detect and dispose of unlinked files from vop_inactive.
    * Fix some inefficiencies in the flush code.  When modifying a chain
      in order to update its blockref array hammer2_chain_modify() was
      recursively setting SUBMODIFIED upward, messing up the flush code's
      sequencing and causing it to not completely flush the topology.
    * Remove some debugging.
