  Log:
  Sync CAM with FreeBSD using lockmgr locks instead of mutexes.
  Note:  This is mostly a code sync with FreeBSD which improves stability
  in addition to the items listed below.  This provides a framework for
  releasing the mplock, but for now it's still there.
  
  Add an xpt_print function to reduce most of the xpt_print_path/printf
  pairs. Convert the core code to use it.
  
  Initial cut at Basic Domain Validation.
  
  Make cam_xpt's pronouncements match camcontrol (Tagged -> Command) Queueing.
  
  Pay attention to return value from xpt_bus_register in xpt_init.
  
  Add an xpt_rescan function and a thread that will field rescan requests.
  The purpose of this is to allow a SIM (or other entities) to request a bus
  rescan and have it then fielded in a different (process) context from the
  caller.
  
  Check the return value from cam_periph_acquire.
  
  Drop the periph/sim lock when calling disk_destroy().
  
  Drop the topology lock before calling the periph oninvalidate and dtor
  vectors.
  
  For the XPT_SASYNC_CB operation, only decouple the broadcast to the bus
  and device lists instead of decoupling the whole operation.  This avoids
  problems with SIMs going away.
  
  Split the camisr into per-SIM done queues.  This optimizes the locking a
  little bit and allows for direct dispatch of the doneq from certain
  contexts that would otherwise face recursive locking problems.
  
  Zero the CCBs when mallocing them.
  
  Only schedule the xpt_finishconfig_task once.
  
  Eliminate the use of M_TEMP.
  
  Add a helper function for registering async callbacks.
  
  Release the bus reference that is acquired when doing a CAMIOCOMMAND ioctl.
  
  Zero scsi_readcapacity allocations so we can really tell if there has
  been data returned.
  
  Remove duplicate includes and fix typos.
  
  Add a bunch of definitions and structures to support newer drivers.
  
  When probing a newly found device, don't automatically assume that the
  device supports retrieving a serial number.  Instead, first query the
  list of VPD pages it does support, and only query the serial number if
  it's supported, else silently move on.  This eliminates a lot of noise
  during verbose booting, and will likely eliminate the need for most
  NOSERIAL quirks.
  
  Reduce diffs from FreeBSD.
