Shuffle some SCSIDEBUG code to simplify code, tersify the
emitted verbiage, and show INQUIRY header & vendor info early so
humans can more easily determine what scsi_probe_link() will
do.

No functional change outside SCSIDEBUG.

Refactor scsi_show_flags() to allow 32-bit flags. Display unnamed flags as one
hex value after named flags. Make flag name arrays NULL terminated rathar than
fixed size.

SC_DEBUGN is not spelled SCSI_DEBUGN.

Restore SC_DEBUGN() as it was used outside sys/scsi. Some things are
not compiled on amd64!

Introduce SC_DEBUG_SENSE() and simplify code by eliminating a bunch
of three line SCSIDEBUG chunks.

Continue SCSIDEBUG cleanup by nuking pointles SC_DEBUGN() #define.

Tweak some whitespace to make autoindenter happy. Use consistent naming idiom for
the debug functions.

Use consistent idiom/naming convention for the the #include
guards. Spelunkers using grep are easily confused.

Add/tweak #endif comments to make spelunking via grep more rewarding.

Shuffle and consolidate SCSIDEBUG declarations into fewer sections in
more intuitive locations.

Fix a broken compilation when using SCSIDEBUG options(4).

Diff from Carlos Cardenas, thanks!

Standardize on calling local scsi_link variables 'link' instead of
'sc_link'. 'sc_link' is a field in the various device *_softc
structures, where the sc_ prefix was for 'softc'. Reduces potential
mental confusion. Newer code from down under was already using
'link'.

No functional change.

Prompted by bluhm@'s adventures in scsi. ok dlg@ jmatthew@

More damned eye searing whitespace.

scsi_link's scsibus field is redundant with bus->sc_dev.dv_unit, so
remove two of the remaining three uses of it. (softraid(4) still uses
it at the moment, so the field and its assignment in scsibusattach()
stay for now...)

ok krw@; feedback and "tenteiramen rejid"(!?) miod@

clean namespace a fair bit; wrap kernel-use-only structures and gunk in
#ifdef _KERNEL

Allow restriction of SCSIDEBUG output to particular scsi buses in
addition to device targets and luns.

ok deraadt@.

branches: 1.7.12;
Add SCSITERSE option which omits the (large) ASC/ASCQ table.
Old scsi error printing code is now gone.

Add more detailed SCSI error printing by Matthew Jacob. Enabled by
default. Use "option SCSIVERBOSE=0" to turn off (only added 8Kb to my kernel).
From the NetBSD commit message:
Add in more detailed SCSI error printing, based off of final SCSI-2 spec.
This will also print out things like progress indicator errors, and will
also dump out additional sense bytes that haven't been decoded.

Merge in various pieces of current NetBSD scsi code, including but not limited
to:

* New changer driver.
* Better optical support.
* Different `done' semantics.
* New quirks for SCSI QIC tape driver, SCSI floppy drives.
* Better support for SCSI-I devices.

Everybody needs to test this.

Make SCSI debugging more dynamic, more targets and luns can be
debugged simultaneously and which ones, as well as the verbosity, can be
determined at runtime.

$OpenBSD RCSIDs + comment fix in sd.c

Several changes:
* Implemented NetBSD PR#2529, adding ZIP 100.
* Added MTIOCTOP support to acd, cd, and sd.
* Implemented eject on close for acd, cd, and sd.

`mt -f /dev/rcd0d offline' now ejects a mounted {acd|cd|sd} when it is
unmounted.
