- Remove deprecated SCSI_IOCTL_SEND_COMMAND interface.
- Remove deprecated /proc/scsi/3w-xxxx interface.
- Convert entire driver to pci_driver format.
- Remove all mdelays, replace w/msleep to fix possible watchdog
  timer issues.
- Make all register accesses macros.
- Remove all prototypes from header file, reorder functions to
  eliminate all prototypes but one.
- Add sysfs 'queue_depth' setting attribute.
- Add sysfs 'stats' attribute.
- Fix spinlocks everywhere, remove tw_lock spinlock.
- Remove all bitfields, add bitmask access macros.

  support aborting invididual IO's, scsi_eh_reset sufficient.
