Remove OLDCARD shims

Eliminate unused argument in PCMCIA_CARD macro.

Provide a backwards compatible way to have the extra macro by defining
PCCARD_API_LEVEL 5 before including pccarddevs for driver writers that
want/need to have the same driver on 5 and 6 with pccard attachments.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

Start each of the license/copyright comments with /*-, minor shuffle of lines

Fix disordering of pccarddevs.h noticed by bde. Also remove a few
redundant includes and fix some of the include disordering.

Submitted by: bde

Move to generating pccarddevs.h on the fly, both for the kernel and
the modules.

Also generate usbdevs.h automatically now, but a non-kernel file is
stopping that at the moment.

Move the non-MD machine/dvcfg.h and machine/physio_proc.h to a common
MI area before they proliferate more.

Use __FBSDID().
Also some minor style cleanups.

Make sure that pp_name is non-null before setting the device
description. This allows us to rely entirely on the CIS entries if
necessary...

- Add PCI support (Adaptec AHA-2920/A,Future Domain TMC-18XX/3260).

Remove PAO3 dependent part.
This will not affect either -current nor -stable.

We should not pass the size of the memory to bus_alloc_resource().
We should use 1 to request default iomem.

Catch up with NetBSD/pc98.
o Much cleanly separate NetBSD(XS) / FreeBSD(CAM) codes.
o Improve tagged queing support (full QTAG).
o Improve quirk support.
o Improve parity error retry.
o Impliment wide negotheation.
o Cmd link support.
o Add copyright of CAM part.
o Change for CAM_NEW_TRAN_CODE.
o Work around for buggy KME UJDCD450.

o stg: add disconnet condition.
o nsp: use suspend I/O.
and more. I thank Honda-san.

Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

o Check the size of I/O window handed by parent bus.

- Move stg_card_intr()'s prototype and definition inside appropriate
#ifdef's as it is is only used on older versions of FreeBSD.
- #ifdef a local variable only used on older versions of FreeBSD.

Zap some cut-paste code that isn't used. It #included "apm.h" and
an apm include file but had no other apm references.

select() DKI is now in <sys/selinfo.h>.

Remove unnecessary printf().

Add PC-Card/ISA SCSI host adpater drivers from NetBSD/pc98
(a NetBSD port for NEC PC-98x1 machines). They are ncv for NCR 53C500,
nsp for Workbit Ninja SCSI-3, and stg for TMC 18C30 and 18C50.

I thank NetBSD/pc98 and bsd-nomads people.
