Move setting of scsi_verbose_loaded flag into the module's init routine.
This ensures that the flag is set even if the module was manually loaded
by the user rather than just auto-loaded.

Update scsiverbose module to use module_autoload() rather than module_load().
Load the module right before each attempt to use its features, and let the
module subsystem handle unloading.

Extract SCSIVERBOSE into a kernel module. The module can be builtin
by defining 'options SCSIVERBOSE' in the kernel config file (no change
from current behavior), or it can be loaded at boot time on those
architectures that support the boot loader's "load" command.

The module is built for all architectures, whether or not SCSI or
atapi support exists.

Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.

Backing out changes to clean up scsipi. I was pointed out there were
problems i hadn't seen. To prevent lossage i'd decided to back off all
changes and let them be reviewed on tech-kern.

As part of cleaning up sys/scsipi, replace all u_char by uint8_t and
replace all `short' with int16_t.

Use ANSI function decls and make use of static.

use bounded string ops

sprintf -> snprintf

cbd -> cdb
Command Block Descriptor -> Command Descriptor Block
Pointed out by Allen Briggs.

Extract the code printing the CBD from scsipi_print_sense(), so that it's
usable in other context.
Use the new scsipi_print_cbd() to dump the command in case of timeout
in siop/esiop.

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.
