    kernel - Add kqueue and fix chflags handling for tmpfs
    
    * Implement kqueue ops for tmpfs so things like tail -f work properly.
    
    * Redo all the chflags handling and checks to use the helper functions,
      also getting ridding of the horribly broken FREAD/FWRITE tests on
      node->tn_flags (which is the chflags flags, not the open flags).
    
      This fixes chflags handling for tmpfs.  Previously doing something
      like 'make installkernel ... DESTDIR=<sometmpfs_target>' would fail
      on re-install due to chflags not working properly.
    
    * Fix a lost node unlock in tmpfs_chflags()
