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
