This used the be the primary header file for Capsicum, but we switched 
to the somewhat-more-portable sys/capsicum.h awhile ago. The current 
sys/capability.h includes the new header while emitting a warning in 
order to encourage people to switch to capsicum.h without breaking 
anything (yet). This is a transitional step, and I think the plan is to 
remove sys/capability.h after... maybe the 12-STABLE branch?
