fredette 23aa52421d No longer assume that !DDB implies that Debugger() isn't defined.
Now only define Debugger() if it isn't defined already.

bouyer 937a7a3ed9 Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.
