X680x0 IOCS library.

Specify default SCSI inquiry size (36 bytes) on IOCS_S_INQUIRY() command.

X680x0 SCSI IOCS stalls if SCSI device doesn't return inquiry data
of specified allocation length size on the INQUIRY command,
and it causes hangup on the XM6 based emulators that return only
upto 36 byte inquiry data on SCSI disk emulation.

Many real SCSI-2 hard drives seem to support >100 byte inquiry data,
but at least there is a harddisk that returns only supported inquiry
data size and quits transfer.

The bootloader checks only the device type and there is no reason
to read 100 bytes that includes vender specific data.

Analyzed and reported by GIMONS, a developer of XM6 TypeG emulator,
which also can run NetBSD/x68k.

Due to the way these files are used, ref. libdos/makedoscalls.awk and
libiocs/makeiocscalls.awk, we need a space between the function name
and the parameter list in the declaration.

X680x0 IOCS library.

Overhaul xxboot. And merge floppy boot, taken from boot_ustar.
- Rewrite boot.S completely.
boot.S now supports boot from SCSI HD/CD and floppy.
- Use IOCS call to identify the floppy format, instead of chkfmt.s which
accesses hardware directly.
- Import print_hex() debug function from boot_ufs.
- Import a feature that displays initial registers (for debug) from boot_ufs,
and restore it (this in boot_ufs has been broken).
- Add size optimized alternatives for some libkern routines.
- Stop linking libsa to prevent to link unexpected objects.
- Bump version to 2.0.

Initialize the screen in all primary bootloaders.
- Some IPL (or boot selector) don't do it, but current secondary bootloader
expects the screen to be initialized to display logo.
To keep messages (like version signature) displayed by primary bootloader,
this initialization should be done early in all primary bootloaders.
- For boot_ustar.S, relocates some registers to save bootinfo (%d0).
- Bumps version.

Confirmed on X68030+060turbo and my X68030. This problem was found on
X68030+060turbo at NetBSD booth in OSC 2011 Hiroshima (8+ years ago).
