scsi: print single-character strings with seq_putc

Using seq_putc to print a single character saves at least a strlen()
call and a memory access, and may also give a small .text reduction.

scsi: replace seq_printf with seq_puts

Using seq_printf to print a simple string is a lot more expensive than
it needs to be, since seq_puts exists. Replace seq_printf with
seq_puts when possible.

scsi: use 64-bit LUNs

The SCSI standard defines 64-bit values for LUNs, and large arrays
employing large or hierarchical LUN numbers become more and more
common.

So update the linux SCSI stack to use 64-bit LUN numbers.

[SCSI] aic7xxx: Remove OS utility wrappers

This patch removes malloc(), free(), and printf() wrappers from the aic7xxx
SCSI driver. I didn't use pr_debug for printf because of some 'clever' uses of
printf don't compile with the pr_debug. I didn't fix the overeager uses of
GFP_ATOMIC either because I wanted to keep this patch as simple as possible.

[SCSI] aic7xxx: Remove slave_destroy

This is a cross-port from aic79xx; we still hit the occasional
BUG_ON in slave_destroy. And again we don't really need the
slave_destroy callback nor the ahc_linux_target structure
at all.

[SCSI] aic7xxx: remove aiclib.c

#include of C files and macro tricks to rename symbols are evil and just

go away soon enough anyway.

[SCSI] aic7xxx: remove separate target and device allocations

Since the aic driver is now taught to speak in terms of the generic
linux devices, we can now also dispense with the transport class get
routines (since we update the parameters when the driver sees they
change) and also plumb it into the spi transport transfer agreement
reporting infrastructure.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
