The #defines in sun3_scsi.h are intended to influence subsequent #includes
in sun3_scsi.c. IMHO, that's too convoluted.
Move sun3_scsi.h macro definitions to sun3_scsi.c, consistent with other
NCR5380 drivers.
Omit the unused NCR5380_local_declare() and NCR5380_setup() macros.

The *_RELEASE macros don't tell me anything. In some cases the version in
the macro contradicts the version in the comments. Anyway, the Linux kernel
version is sufficient information. Remove these macros to improve readability.

Compile-time override of scsi host defaults is pointless for drivers that
provide module parameters and __setup options for that. Too many macros make
the code hard to read so remove them.

If the host->info() method is not set, then host->name is used by default.
For atari_scsi, that is exactly the same text. So remove the redundant
info() method. Keep sun3_scsi.c in line with atari_scsi.
Some NCR5380 drivers return an empty string from the info() method
(arm/cumana_1.c arm/oak.c mac_scsi.c) while other drivers use the default
(dmx3191d dtc.c g_NCR5380.c pas16.c t128.c).
Implement a common info() method to replace a lot of duplicated code which
the various drivers use to announce the same information.
This replaces most of the (deprecated) show_info() output and all of the
NCR5380_print_info() output. This also eliminates a bunch of code in
g_NCR5380 which just duplicates functionality in the core driver.

Move the #include "NCR5380.h" out of the sun3_scsi.h header file and into
the driver .c files, like all the other NCR5380 drivers in the tree.
This improves uniformity and reduces the depth of nested includes. The
sequence of #include's, #define's and #if's no longer does my head in.

Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.
The patch below presents a simple SCSI host lock push-down as an
equivalent transformation. No locking or other behavior should change
with this patch. All existing bugs and locking orders are preserved.
Additionally, add one parameter to queuecommand,
struct Scsi_Host *
and remove one parameter from queuecommand,
void (*done)(struct scsi_cmnd *)
Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.
Minimal code disturbance was attempted with this change. Most drivers
needed only two one-line modifications for their host lock push-down.

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!
