kernel - Adjust device D_MPSAFE_* flags
* Replace all device D_MPSAFE_* flags with just D_MPSAFE
- Mark CAM's "da" and "cd" devices D_MPSAFE
- Mark dm (device mapper) D_MPSAFE
- Mark memio MPSAFE
- Mark the disk subsystem D_MPSAFE
- Mark the crypto device D_MPSAFE
* Devices marked D_MPSAFE now call their strategy functions without the
mp lock.
* Do a pass on devfs and mark it MNTK_ALL_MPSAFE. devfs was essentially
already MPSAFE but the D_MPSAFE checks have been moved out of devfs
and into the dev_d*() API wrappers.

kernel - dm - Reorganize the crypt code and implement B_HASBOGUS
* Implement B_HASBOGUS data copying for read decryption. When a buffer
contains bogus pages we may or may not be able to safely decrypt data
in-place, add some code to deal with it.
* Reorganize the crypt code. Separate the read and write paths and
organize the procedures in the same order as the execution stages.
Also move some of the buffer manipulation around a little to make
it more clear.
Submitted-by: alexh (B_HASBOGUS handling)

kernel - dm - Add support for BUF_CMD_FLUSH
* Change the nestiobuf_*() code to count the number of sub-bios issued
instead of counting the resid. This allows the nestiobuf_*() API to
be used to BUF_CMD_FLUSH.
* Change the nestiobuf_*() API. The nestiobuf_start() command is now
nestiobuf_add(). Add a nestiobuf_init(mbio) and nestiobuf_start(mbio)
wrapper around the adds.
* Explicitly check for allowed BUF_CMD_* commands in device-mapper.c
* Add a bypass to device-mapper.c to cause certain commands to be sent
to all tbl's (BUF_CMD_FLUSH).
* Add explicit suppor for BUF_CMD_FLUSH to dm_target_stripe.c
* Change b_resid loading semantics to load upon completion of the
I/O.

lvm/dm - clean up debug, fix open bug
* Clean up debug code and change it to log_verbose, mostly. Also remove
some of the older, now irrelevant, comments.
* For dm, add a sysctl and tunable to enable debugging (debug.dm_debug)
* in the dragonfly filter, open the device early enough, and definitely
before closing it ;)
