struct device * -> device_t, no functional changes intended.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Don't use esp_pcmcia_enable() before attaching chip driver (ncr53c9x),
since it touches storage allocated by the chip attach function.
The chip driver properly calls scsipi_adapter_addref() /
scsipi_adapter_delref(), and just deleting the esp_pcmcia_enable() call
and the relevant code should be OK.

Rather than the silly state machine, set whatever higher-level reference
count there is (for SCSI, adapt_refcnt) to 1 and call the appropriate
"delref" function afterwards to disable the controller. This is a bit
simpler.

In a couple of cases, just remove the state machine, because it wasn't
really necessary.

Constify.

Now that all the silly string printing is gone, move the location where we
print a newline so it doesn't have to be done in every driver.

Enhance pcmcia_product_lookup():
* Remove the "expected function" value. This was just causing problems with
multifunction cards. Differentiating the functions is better done by
checking the function type (which we now do in ep and sm).
* Add support for matching CIS strings. This necessitated changing the calling
pattern a little too.

Use this enhanced version rather than driver-specific versions that do the
same thing.

Also, remove the last vestiges of PCMCIA_STR_*.

More careful about cleaning up pointers.

Print diagnostics in only one place if intr_establish() or function_enable()
fails.

Also, be a little more careful about passing up error values, and consistently
clear our interrupt handler pointer.

Update to the new world order.

XXX Note: This eliminates some register writes that were done in the "init"
routine during attach. If these are necessary, they need to do done somewhere
else, quite possibly the enable routine.

Remove the "offset" and "size" arguments to pcmcia_io_map(). In the singular
case (ne@pcmcia) where we were using these to create a subregion, it is better
handled by calling bus_space_subregion().

Now there is a 1:1 mapping between I/O spaces in the config table and windows
mapped in the function. Rework the multifunction mapping code to take
advantage of this by using both I/O base addresses if necessary.

Add support for RATOC REX-9530.
Not fully tested, though.

SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

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.

Well, this is esp_pcmcia, not esp_pci.

Oops, struct scsipi_adapter was changed recently.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Oops; fix a slight biff in the PIO input routine.

Cosmetics. ( 0x80 -> NCRSTAT_INT )

Interrupts work now. Woohoo.

Add esp_pcmcia. For the moment it's polled, since interrupts don't seem to be
working.
