RenamingWhen them with prefix 'cr_cansee' causes confusion because they only returnse functions were renamed 7 years ago, their man pages were not. Rename
whether a specific policy denies access, so a return value of 0 does notthe latter in accordance and fix the names inside them. Fix references to them
actually indicate that some subject is authorized to access another subject or
object in a particular situation.
So remove the 'can' part to closely match the sysctl names (after the
'security.bsd' node), which has the side-effect of renaming back the oldest of
them and making the names of their manual pages actual agains well.
