Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their
queuecommand functions. Those fields are internal storage for the
midlayer only and are used to restore the original payload after
request_buffer and request_bufflen have been overwritten for EH. Using
the buffer and bufflen fields means they do very broken things in error
handling.

Use schedule_timeout_uninterruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.

Wrap a highly common idiom. Makes the code easier to read, helps pave
the way for sdev->{id,channel} removal, and adds a token that can easily
by grepped-for in the future.
There are a couple sdev_id() and scmd_printk() updates thrown in as well.

Fix 12 undefined preprocessor identifier warnings (4 each in 3 driver builds):

NDEBUG and NDEBUG_ABORT are almost always used as integers in NCR5380; added
define to 0 if they are not defined, switched lone ifdef NDEBUG into if.

Drivers need not implement a hook that returns FAILED, and does nothing
else, since the SCSI midlayer code will do that for us.

We have the scsi_print_* functions in the proper namespace for a long
time now and there weren't a lot users left.

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!
