Heads up: s/u_intXX_t/uintXX_t/ in sys/cam

I plan on finally biting the bullet and moving to the standard uintXX_t.

I plan on doing this next week, before we branch 14.

I also plan on  MFC'ing these changes (or rather running the same script
and tagging that commit as a MFC).

This has been talked about forever, and now seems like we have a good lull
in things to do it.

Comments?
