CAM_NEW_TRAN

[mjacob at freebsd.org]

There a number of SIMs that need changes for the CAM_NEW_TRAN code- I 
can't test them all, but it's a pretty straightforward exercise to 
do this.

My plan is to add all of the changes so that LINT+CAM_NEW_TRAN_CODE 
compiles and otherwise test what I have h/w for and check that in.

Once that's done, I'll send an announcement out about a cutover date in 
-current to the CAM_NEW_TRAN_CODE which is going to be the only way to 
actually get this in place and actually tested, and either remove the 
non-CAM_NEW_TRAN_CODE or change the definition so we have 
CAM_OLD_TRAN_CODE.

Questions:

a) If anyone wants reviews of the changes, please say so now. I'll try 
and send diffs to all and sundry as I go along, but I may forget. Again, 
the changes are expected relatively small

b) Should I retain the old code? I would think not. I mean, this stuff 
has been around for years and it just clutters up the screen for the old 
stuff.
