System private functions

actually, I think this is a bad idea — or at least needs significantly more thought!

System-private functions are functions private to the system, which no normal user is entitled to access; these functions normally have an access control value of NIL.

(sys-access-control arg)

System private. Takes one argument. Returns the access control list of its argument.

(sys-readable arg user)

System private. Takes two arguments. Returns TRUE if the first argument is readable by the reader represented by the second argument; else NIL.
