Code Issues Releases Activity

Re-do r255853. Along with adding back the API/ABI changes from the

Browse Source 
original, this hides the contents of cam_compat.h from ktrace/kdump/truss,
avoiding problems there.  There are no user-servicable parts in there, so
no need for those tools to be groping around in there.
