Log Message:
Bring in changes from FreeBSD...
* Allocate commands on-demand.
* Update a bunch of constants and some structures.
* Use __attribute__ ((__packed__)) instead of __packed to be consistent.
* Support more commands for devices that can apparently handle them.
* Support a "new comm. interface" present in more recent Adaptec
  firmware.  This reduces the amount of PCI bus traffic in handling
  commands.
* Support larger commands going to the adapter--if the adapter can
  support them.
* Support 64-bit commands for archs where sizeof(bus_addr_t) > 4 and
  for adapters that advertise SGMAP64.
* Handle the WINDOW4G option and NO4GB quirk by excluding 2G-4G window
  unless we have the WINDOW4G capability without the NO4GB quirk.
* Ask the adapter more about its capabilities and try to use those if
  they seem sane.
* Do our bus_dmamap_sync() inside dequeue_fib instead of following,
  since we have the information that we need there.
* Provide access functions for some adapters that I haven't seen yet
  (MIPS-based "Rocket" adapters).  Not yet used.
