Introduce support for Mandatory Access Control and extensible kernel access control. Extensions to libc to provide basic MAC label manipulation facilities for userland. These interface will be replaced in the next month or two with more flexible interfaces, but provide sufficient support to allow use of the Biba and MLS policies for user applications. libc_r wrappers to follow.
