Introduce support for Mandatory Access Control and extensible

kernel access control.

Provide a library to manage user file system firewall-like rules
supported by the mac_bsdextended.ko security model.  The kernel
module exports the current rule set using sysctl, and this
library provides a front end that includes support for retrieving
and setting rules, as well as printing and parsing them.

Note: as with other userland components, this is a WIP.  However,
when used in combination with the soon-to-be-committed ugidfw,
it can actually be quite useful in multi-user environments to
allow the administrator to limit inter-user file operations without
resorting to heavier weight labeled security policies.
