6810ad6f2a Overhaul driver/subsystem api's:
o make all crypto drivers have a device_t; pseudo drivers like the s/w
  crypto driver synthesize one
o change the api between the crypto subsystem and drivers to use kobj;
  cryptodev_if.m defines this api
o use the fact that all crypto drivers now have a device_t to add support
  for specifying which of several potential devices to use when doing
  crypto operations
o add new ioctls that allow user apps to select a specific crypto device
  to use (previous ioctls maintained for compatibility)
o overhaul crypto subsystem code to eliminate lots of cruft and hide
  implementation details from drivers
o bring in numerous fixes from Michale Richardson/hifn; mostly for
  795x parts
o add an optional mechanism for mmap'ing the hifn 795x public key h/w
  to user space for use by openssl (not enabled by default)
o update crypto test tools to use new ioctl's and add cmd line options
  to specify a device to use for tests

These changes will also enable much future work on improving the core
crypto subsystem; including proper load balancing and interposing code
between the core and drivers to dispatch small operations to the s/w
driver as appropriate.

These changes were instigated by the work of Michael Richardson.

082a4bab02 - Remove HMAC_BLOCK_LEN, it serves no purpose.
- Use defines of used algorithm instead of HMAC_BLOCK_LEN.

9a2f606177 Add support for the CRD_F_KEY_EXPLICIT flag for both encryption and
authentication operations.

Unfortunately I've no hardware, so I only compiled-tested it.

HMAC. crp_mac is going to be removed.

d2b677bb1a Use BUS_PROBE_DEFAULT in preference to 0 and BUS_PROBE_LOW_PRIORITY in
preference to some random negative number to allow other drivers a
bite at the apple.

c06eb4e293 Change instances of callout_init that specify MPSAFE behaviour to
use CALLOUT_MPSAFE instead of "1" for the second parameter.  This
does not change the behaviour; it just makes the intent more clear.

900017e84b o add missing {}'s that to safe_dmamap_uniform that caused extraneous copies
for partly-aligned operations through /dev/crypto (unlikely)
o add missing case in iov code that never showed up because of the above bug
