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.
and more. I thank Honda-san.
conf/options.pc98: add CT_USE_RELOCATE_OFFSET and CT_BUS_WEIGHT
dev/{ct,ncv,nsp,stg}/*_{pccard,isa}.c: add splcam() before calling
attach/detach functions.
