Check a status code and return proper errno in sdstrategy().

Suggested by gcc 4.8 -Wunused-but-set-variable warning to use the variable.

Misc KNF and cosmetics.

Reorgenize boot device configuration.  The idea is taken from OpenBSD/luna88k.

- remove kernel-like autoconfiguration to probe bootable devices
- initialize SCSI and Ethernet controllers statically instead
- reorganize device softc structures per autoconf removal
- probe and print all SCSI disks (but don't assign unit numbers)
- make sdopen() to recheck the device and allocate softc dynamically
- use controller number and SCSI target ID (ctlr * 10 + id) to specify
  the boot disk on the "boot" command arg
- bump version to denote changes

Now bootloader works as the following:

Pull more cleanups from OpenBSD/luna88k:

- remove unused declarations
- rename struct scsi_fmt_cdb to scsi_generic_cdb

Misc cleanup from OpenBSD/luna88k.

- remove unused code
- use proper prefix for structure members for readability

Remove unused code (from OpenBSD/luna88k). Some KNF.

Whitespace cleanup.

Slightly modify sd attach message, as kernel does.

Fix drivers to make secondary SPC SCSI on LUNA-II work properly.
Also bump version.

Now we can load a NetBSD kernel from external SCSI disks on LUNA-II.
(and netboot on LUNA-II also works)

Remove unused function members from struct driver.
This makes adding other drivers easier.

First cut at NetBSD/luna68k native bootloader.

Based on 4.4BSD-Lite2/luna68k "Stinger" loader revision "Phase-31"
 http://svnweb.freebsd.org/csrg/sys/luna68k/stand/
and MI libsa glue stuff are taken from hp300 etc.

Tested on LUNA-I and old DK315C SCSI disk drive.

LUNA's monitor PROM can load only an a.out binary in 4.3BSD FFS partition
(i.e. created by "newfs -O 0") on disks with OMRON's UniOS disklabel,
but now we can load an ELF kernel in root partition via this bootloader.
(See luna68k/disksubr.c for details of UniOS label)

TODO:
 - LUNA-II support (check 68040 to adjust cpuspeed for DELAY())
 - secondary SCSI support for LUNA-II
 - netboot via le(4) (should be trivial)
 - support boot options on bootloader prompt
 - bootinfo (passing info about booted device and kernel symbols)
 - support "press return to boot now, any other key for boot menu" method
   like x86 bootloader (needs cnscan() like functions)
 - tapeboot (anyone wants it?)
