kernel - Fix bug in x86-64 version of bzeront()
* The x86-64 bzeront code was subtracting the wrong value from the count
when looping. Note that prior to this commit the code was not being
used anyway.
* Rearrange the way movnti support is detected and enable for x86-64.

dm - undo my pointless moving of dm.h
* There was no need to move dm.h, we can just use <dev/disk/dm/dm.h>.
* And since we can do the above, we can also get rid of the strange
Makefile CFLAGS magic I added.
* Also undo the removal on upgrade of /usr/include/dev/disk/dm/dm.h and
instead remove sys/dm.h

Add a hexdump(9) manual page (taken from FreeBSD).

kernel - Fix mbuf header exhaustion w/ degenerate unix domain socket case
* Increase the number of mbuf headers to accomodate a degenerate
fd-passing case with chains of unix domain sockets, one fd per
socket.
* This does not address other mbuf exhaustion issues which can crop
up in a user ddos attack due to the default number of fds a user
is allowed to own.

kernel - Fix deep stack recursion in unix domain socket garbage collection
* A chain of unix domain sockets with the previous fd passed into the
next one can cause a kernel stack overflow.
* Flatten the portion of the gc which would otherwise recurse by placing
the fp on a list instead of calling a nested closef(), then running
the closes at the top level.

installer - encrypted root fix for new modules
* With the new modularized dm, dm_target_crypt will have to be loaded
explicitly if the module_path is not reachable in the moment the crypt
target is needed.
* Simply write dm_target_crypt_load="YES" to the installed loader.conf
so that there are no nasty surprises.

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
