f6d4af7c72 Define 'struct label' in _label.h rather than mac.h, which will permit
us to reduce namespace pollution by doing a nested include of _label.h
rather than mac.h.  mac.h contains lots of baggage, whereas _label.h
contains much less.  A follow-up sweep to change nested inclusion will
follow.  The problem regarding exporting 'struct label' to userland
due to excessive exporting of kernel structures to userland still
needs to be resolved.

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)

ddcdf2650b 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.

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.
