the CAM_NEW_TRAN_CODE that has been in the tree for some years now.
This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).
After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.
This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

module-specific malloc types. These should help us to pinpoint the
possible memory leakage in the future.
- Implementing xpt_alloc_ccb_nowait() and replacing all malloc/free based
CCB memory management with xpt_alloc_ccb[_nowait]/xpt_free_ccb. Hopefully
this would be helpful if someday we move the CCB allocator to use UMA
instead of malloc().

Devices below may experience a change in geometry.
* Due to a bug, aic(4) never used extended geometry. Changes all drives
>1G to now use extended translation.
* sbp(4) drives exactly 1 GB in size now no longer use extended geometry.
* umass(4) drives exactly 1 GB in size now no longer use extended geometry.
For all other controllers in this commit, this should be a no-op.

in geom_disk.c.
As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.
o Much cleanly separate NetBSD(XS) / FreeBSD(CAM) codes.
o Improve tagged queing support (full QTAG).
o Improve quirk support.
o Improve parity error retry.
o Impliment wide negotheation.
o Cmd link support.
o Add copyright of CAM part.
o Change for CAM_NEW_TRAN_CODE.
o Work around for buggy KME UJDCD450.
o stg: add disconnet condition.
o nsp: use suspend I/O.

o Offset and period in synch messages and width negotiation should be
done for per target not per lun. Move these from *lun_info to
*targ_info.
o Change in handling XPT_RESET_DEV and XPT_GET_TRAN_SETTINGS .
o Change CAM_* xpt_done return values.
o Busy loop did not timeout. Change this to timeout as original NetBSD/pc98.
