4b826b4cfc Change macop_t to const, use macop_t in MAC policy entry point definition
structure.  This prevents a boatload of warnings in the MAC modules,
so we can hook them up to the build.

9453a033ff Reduce the memory footprint of MAC in the base system by halving
the number of policy slots to 4.

(Having run a quick errand, time to start on phase 2 of the MAC
integration)

95fab37ea8 Begin committing support for Mandatory Access Control and extensible
kernel access control.  The MAC framework permits loadable kernel
modules to link to the kernel at compile-time, boot-time, or run-time,
and augment the system security policy.  This commit includes the
initial kernel implementation, although the interface with the userland
components of the oeprating system is still under work, and not all
kernel subsystems are supported.  Later in this commit sequence,
documentation of which kernel subsystems will not work correctly with
a kernel compiled with MAC support will be added.

kern_mac.c contains the body of the MAC framework.  Kernel and
user APIs defined in mac.h are implemented here, providing a front end
to loaded security modules.  This code implements a module registration
service, state (label) management, security configuration and policy
composition.

Include files to declare MAC userland interface (mac.h), MAC subsystem
entry points (mac.h), and MAC policy entry points (mac_policy.h).  These
files define the interface between the kernel and the MAC framework,
and between the MAC framework and each registered policy module.  These
APIs and ABIs may not be assumed to be stable until following FreeBSD
5.1-RELEASE.

7bc8250003 Stubs for the TrustedBSD MAC system calls to permit TrustedBSD MAC
userland code to operate on kernel's from the main tree.  Not much
