    dm - Modularize it fully
    
    * Move each of the targets (except error and zero) into a subdirectory
      in targets/.
    
    * Change the macro DM_TARGET_MODULE to also let the module depend on dm.
    
    * Add a new macro DM_TARGET_BUILTIN, which must be used instead of
      DM_TARGET_MODULE for targets that are compiled into the main dm.ko
      instead of a separate module. Not doing this will prevent dm.ko from
      unloading.
    
    * Enable automatic loading of target modules if they aren't builtin or
      loaded yet. Automatically loaded modules can be unloaded via kldunload
      safely via a little hack (see source).
    
    * NOTE: automatic loading doesn't always work. /boot must be mounted
      already, so if you are planning on encrypting your swap or similar
      stuff, you need to *EXPLICITLY* load dm_target_crypt.ko via the
      loader.
    
    * NOTE: PLEASE NOTE THE NOTE ABOVE!
    
    * Fix a little issue with dm_target_crypt that would print "unloaded"
      even if it wouldn't unload.
    
    * Change the name of dm_target_stripe to dm_target_striped, since the
      target is actually called "striped".
    
    * Move dm.h to sys/sys/dm.h
    
    * Get rid of files.dm, a leftover from the import
